PRESIDENT'S COMMENTS

One of the great tasks facing all professionals is "keeping up." Art Greenof Exxon Production Research Co. recently estimated that since only 1980, thegeological literature has nearly doubled. The cumulative number of books andarticles published since 1785 increased from 677,000 in 1980 to 1,202,000 in1988. Currently, the literature is growing at more than 67,000 items per year.With such voluminous publication, it is obvious that all of us face a difficult taskkeeping up...not only technically but businesswise as well. We don't keep upmerely to demonstrate that we recently read a journal or a book. We must do itin order to produce products that sell.

Traditionally, we jump on a high learning curve after school and master thebasics of our business. After a few years, the learning slows down and wespend more time practicing our profession and doing more things by"experience." That's fine...but today experience means less and less becausetechnoiogy is expanding at a rate never seen before.

Obviously this explosion of understanding and of new ways to dotraditional activities radically alters not only traditions but more importantly,career paths and ways to keep current. When we were in school, ourprofessors largely performed the task of selecting the best reading. But eventhey are having a hard time today. Similarly, the practicing geologist finds thatas the career evolves, professional, social, and familial responsibilities increasethereby leaving little time for "keeping up." Employers don't always help mucheither because the popular management philosophies are so goal oriented.They work wonders at organizing teams to accomplish complex technicaltasks, but they don't include much time for "keeping up." Yet we try.

Each of us finds favorite ways to battle creeping obsolescence. Like manyof you, I enjoy the meetings; usually I learn as much from the table discussionsas from the formal talks. In addition, I usually meet some folks of kindred spiritand, of course, see several "regulars." The latter have discovered that listeningto others is a very efficient means to learn the important things. Seems thatconversations produce a filtering mechanism and one is almost certain to hearthe significant news. Granted, it's not focused but it is effective: remember howfast word of any recent discovery gets around? I explain to my boss (who's notan HGS member), that even though my daily activities rarely change as theresult of a meeting, the cumulative effect of hearing the technical discussionsand meeting new business people over the course of the year is quitesignificant. It is a great feeling to call people you met recently and ask fortheir insight; you benefit and they appreciate it. Over the course of a few yearsyou can expect to meet many leaders of both business and science...and you'llboth be the better for the acquaintance.

******

Now we must turn to something that is going to be a lot of work for all ofus: registration of geologists in Texas. Most of you probably feel thatregistration is inevitable...and that may well be the case. Nonetheless, the typeof legislation is not inevitable. A quote from H. L. Mencken perhapssummarizes our current circumstances: "Injustice is relatively easy tobear...what stings is justice." If the Legislature passes a lousy bill, surely it willsting all of us.

I have the impression that most geologists, the younger members andinterstate companies in particular, have not thought much about registration.Apparently, the attitude is that the 'grandfater clause' willnot cause us anyimmediate personal or corporate -inconvenience. This is unfortunate becausewe practicing professionals and our employers are responsible for both ourfuture and the legacy we leave to those entering the profession.

The HGS has no "official" position on the bill but we are trying tocommunicate with our members and to provide a means to communicate tothe Texas Legislature. We are especiaIly fortunate that Past HGS President

J

Dan Smith, who is the AAPG-DPA area representative, also has agreed to be the HGS "point man." This means that Dan will keep abreast of the bill's progress and write updates for the Bulletin (such as those written by Dan Smith this month). In addition, Dan will offer his insight on the quality of the bill, the role of other organizations (such as AAPG and AIPG) and how you might try to amend it if appropriate. This may be a very taxing service and we all owe Dan a hearty 'thanks.'

* * * * *

Don't forget that our evening speaker this month is Jim Lewis, President of AAPG and a Houston independent. This is a great chance to receive a broader view on registration and for you to ask him about AAPG's role/responsibilities.

See you at the meetings and enjoy a happy Thanksgiving.

DICK BISHOP

HOUSTON GEOLOGICAL AUXILIARY The first HGA Board Meeting was held at the home of

our President, Myrtis Trowbridge, on September 22. After the business meeting, a delicious luncheon was enjoyed by all.

The fall season began on Wednesday, September 27, with "Luncheon at River Oaks Country Club." Our speaker was Jan Carson, TV Channel 2 Anchor Woman. A special "thank you" goes to Laurie McDonnough, Suzanne Womack and their committee for a lovely party.

The 1989-90 yearbooks were distributed to all that attended the luncheon and those unable to attend received their copy by mail. A "thank YOU" to Co-Chairmen Marilyn Harrison and Fran Hennington and their committee for a job well done.

Don't forget to mark your calendar for our next party on Tuesday, December 5 which will be held at the Hyatt Regency West.

LADIES, it's not too late to join the Auxiliary. Our membership application is included in this bulletin.

HGS LUNCHEON MEETING-NOVEMBER 29, 1989

A CASE HISTORY OF VELOCITY PROBLEMSIN THE SHADOW OF A LARGE GROWTH FAULT IN

THE FRIO FORMATION, TEXAS GULF COASTFalse structure can appear on seismic data in the

shadow of normal growth faults, with the up thrown timestructure appearing to roll into the fault where no such rollexists in depth. This phenomenon was encountered in aprospect in the Frio formation of the Texas Gulf Coast,where a large growth fault expanded a thick, low-velocityshale above the Frio. Two check-shot velocity surveys, oneat either end of the seismiccontrol, demonstrated a severeaverage velocity gradient across the prospect at the level ofthe objective geologic formation.

Assuming first one and then the other velocity surveywas validover the entire area forconversionof welldata totime produced a drastic difference in the structural inter-pretations of the seismic data. The more obvious interpre-tation required a down-to-the-northwestfaultwitha down-thrown rollover anticline at the objective formation. Thisinterpretation had been previously tested with a dry hole onthe crest of the time structure. This interpretation alsocontradicted a dipmeter in this "crestal" well.

Usinga modelderivedfromintervalvelocitiesfromthenearby check-shot surveys, we were able to demonstratethat over 200 ms of apparent seismic dip in the shadow ofthe growthfaultwasfalse.Whenweused stackingvelocitiesto perform a depth conversion of the seismictime section,

both the apparent dip direction of the formation andinterpreted throw direction of the fault were reversed.Based on these results, awell wasdrilledwhichdemonstrat-ed the qualitativesuccess ofour model.We alsodiscoveredthat minor buried faulting mapped behind the major faultwas a false effect caused by velocity contrasts across thegrowth fault.

This case history proves that the recognition andproper use of velocity gradients can be extremely importantin the Gulf Coast.

ANNUAL CONVENTION SOUTHWEST SECTION AAPG

The Technical Program Committee for the 1991 Annual Southwest Section-AAPG Convention to be held in Abilene, Texas, February 9-12,1991, asks your assistance in preparing a program of high quality papers for our meeting. If you have a person who has done research, written a paper or done a thesis on a geological or technical development that would be of interest to geologists of the SWS-AAPG, we extend an invitation to them to present a paper at our annual meeting.

The committee wishes to compile a program that will present the latest in scientific thinking and technical developments - ideas which can be put to immediate and practical use. The committee will consider papers of outstanding merit in all subject areas, especially those directly applicable to the geological provinces and adjacent basins of the Southwest Section - AAPG.

If you know of someone who is engaged in such appropriate studies, and who would be interested in presenting those studies a s a paper at the 1991 SWS - AAPG Convention meeting, please have them contact me for further information.

Theodore C. Bartlingreceived his B.S. from OhioState University.

Mr. Bartling was em-ployed by Pittsburgh PlateGlass Co. from 1947 to1949, and by W. C.McBride from 1949to 1955.From 1955 to 1968 he wasSenior Vice-President incharge of exploration andproduction for ApacheCorporation, and presi-dent of Ada Oil Explorationfrom 1968 to 1971. From

1971 to the present he has been president of his owncompany, Bartling and Associates.

He has presented papers to many professional societies.PETROLEUM EXPLORATION AND GEOLOGY

OF THE AEGEANThe present day Aegean Sea covers several graben

and/ or half-graben basins that are filledwith over 12,000feetof sedimentary rocks. The normal faulting that is observedon seismic record sections indicates a tensional tectonicregime. There is a marked coincidence of modern basinsand bathymetric highs with paleo basins and highs. Astratigraphic section of marine clastics of Eocene throughMia-Pliocene age have been encountered in the sevenwildcat wells that have been drilled.

Cretaceous age rocks must be considered basement forpetroleum exploration because, except for an area in theEastern Aegean, Cretaceous and older rocks were meta-morphosed during the Alpine orogenies. The Eocene is atransgressive clastic sequence. The Oligocene is conform-able with the underlying Eocene. The Miocene is pre-dominantly a regressive clastic sequence. This series endedwith evaporitic conditions. The Messinian evaporite is anexcellent seismic marker, and is the seal for the oneproducing field in the Aegean Sea. Source rocks andreservoir rocks are found in both the Eocene and theMiocene.

Four of the seven wildcats that have been drilled haveencountered shows of hydrocarbons. Prinos Field, dis-covered in 1974, was put on production in 1981, and iscurrently producing at design capacity of 25,000 to 28,000barrels of oil per day. Cumulative production is approxi-mately 50 million barrels. Prinos field is only seven milesdistant from metamorphic basement outcrop, yet field wellshave penetrated over 10,000feet of Tertiary marine clastics.

An electric log cross section and a series of paleogeo-graphic maps will be used to demonstrate the geologichistory. Several seismic record sections and seismic timemaps will be shown to illustrate the type of stratigraphicand structural features that make up the subsurface of theAegean Sea.

GEOLOGISTS

Notes From The Chair This column will be shorter than those written for past

issues due to the open letter which follows. The letter was originally written for and included in the brochure for the AIPG Texas Section Annual Convention this past Septem- ber. It has also been submitted for publication in the AIPG national publication("The Professional Geologist") and the AIPG Texas Section newsletter ("Certified Professional Geologist").

This month is a fairly busy one for environmental related activities. On November 8th, of course, is the Environmental/Engineering Geology Committee business meeting. The speaker for this meeting has not been confirmed as of this writing. (You must remember that this column is submitted six weeks prior to the month of publication.) Join us on the 8th to find out who the mystery speaker will be. Plan also to stay for the business portion of the meeting. This second half is the heart and soul of the Committee. We have many activities in development and are always in need of energetic individuals willing to share their time and talents.

November 10th is the Texas Hazardous Waste Management conference on "Corporate and Personal Environmental Liability and Its Effect on Industry". An announcement is printed elsewhere in the Bulletin with details (see page 8). November 11th is the HGS Environ- mental Committee's field trip entitled "ENVIRON- MENTAUENGINEERING GEOLOGY OF THE TEXAS COAST: Colorado River Delta to Brazos River Delta" (formerly called the Coastal Environmental Problems Field Trip). An announcement and application form are also printed elsewhere in the Bulletin (see page 18). November 15th through the 17th is the National Water Well Association (NWWA) conference titled "Petroleum Hydrocarbons and Organic Chemicals in Ground Water: Prevention, Detection and Restoration". All members of the NWWA already know about this conference and have probably registered months ago. My comments here are directed to non-NWWA members. All activity takes place at the Westin Galleria starting with on-site registration from 2-5:00 on the 14th, all day on the 15th, as well a s during parts of the 16th and 17th. The exhibit hall opens at 8:00 a.m. on the 15th, and the first paper is presented at 1:30 on the 15th. Anyone interested in the environmental business should attend this conference if possible, if for no other reason than to review the job postings usually placed near the registration booth.

The Environmental/Engineering Geology Committee's dinner meeting, normally held on the 4th Tuesday of the month, has been moved to December 4th, in order to avoid any possible conflicts with the Thanksgiving holiday. This December 4th meeting, co-sponsored with the AIPG Texas Section, will be held at the Piccadilly Cafeteria at the Memorial City Shopping Center on Interstate-10 at Gessner. (The cafeteria is located in the shopping center near the north mall entrance to Sears.) Our guest speakers, Robert Ringholz and Bill Elsbury, both with McClelland Engineers, will discuss "The Long Point Fault and the

I-lO/Sam Houston Tollway Interchange". This should prove to be an interesting presentation. After the talk the Environmental/Engineering Geology Committee will hold a brief business meeting.

Dear Environmental Employers,

With the environmental regulations in Texas expected to tighten, and with the definition of what is "clean" expected to reach lower thresholds, more sites will be classified as contaminated, and old sites once thought to be closed will require additional work to bring them in line with the new standards. This will mean more job openings, especially at the project manager (entry-level and near entry-level) and technician positions. More positions will need to be filled than there are graduates with hydrogeology or engineering geology degrees to fill them.

There are quality geologists/engineers eager and willing to do whatever is necessary to earn the opportunity to apply their skills to a new "environment". They have experience in technologies being applied by some environmental companies (that is, wireline logging and geophysical techniques). They have writing skills, some have computer modeling experience, and all are very much aware of the importance of finishing a job on time and onlunder budget. They are field tried and tested, mature and responsible. They have families to feed and bills that demand payment. Here lies a resource of talent and eagerness which has largely been overlooked.

How does one find these individuals without being swamped by resumes and phone calls? Contact the Houston Geological Society (HGS) Environmental Committee ('The Committee'). The Committee has formed a subcommittee dedicated to actively assist the former petroleum geologist/engineer to make the transition from the petroleum industry to the environmental industry; to assist in their retraining by providing low cost, field oriented seminars covering such topics as groundwater sampling, truck mounted rotary rig drilling using hollow stem augers, real estate transfer site assessments, and UST (gas station) hydrogeologic assessments to name a few. The list is open ended. If you as an employer hesitate to hire applicants because they lack a particular skill or skills, let The Committee know. Perhaps we can work out a program with you to satisfy your needs.

You can reach The Committee through Robert Rieser, Chairman:

by phone: 713-463-6151 home, till 10 PM (leave a message on my recorder and I will return your call if I am not immediately available)

by mail: 5423 Cairnleigh Dr., Houston, TX 77084 or 1213 West Loop North, Suite 100, Houston, TX 77055.

CONFERENCE DESCRIPTION Petroleum hydrocarbons pose a significant threat to

ound water supplies. The U.S. EPA estimates that there e more than 2 million underground storage tanks in the nited States and that 20 percent of them leak. Fortun- ely, technological breakthroughs have led to greater .evention and early detection of tank leaks.

Furthermore, environmental investigations have pro- 3ed useful information concerning the occurrence of ldrocarbons in the subsurface. Many of the mysteries lated to detection and remediation of petroleum hydro- rbons in ground water have beensolved. Still, there i sa lot learn.

This annual meeting focuses o n innovative research -ejects and field studies t o provide insight into petroleum ldrocarbons and other organic chemicals in ground water. 1e 1989 program will feature more than 40 high-caliber ipers covering the following topics: prevention of contami- itions, hydrocarbon measurement, searching for lost ~drocarbons . bioreclamation, establishing cleanup levels, ansport and fate (hydrocarbon migration), organics in ds, liquids recovery and treatment, soils cleanup, and mtaminant migration.

The Association of Ground Water Scientists and ~g inee r s (division of NWWA)and the American Petroleum stitute encourage all persons interested in learning more )out hydrocarbons in the subsurface to at tend the meet- g. More than 800 professionals will b e on-hand.

FEATURED PRESENTATIONS Lee Thomas, C E O and chairman of the board of Law

ivironmental, Kinnesaw, Georgia, will be the keynote ~ e a k e r . Before joining Law, Thomas was the Administrator the U.S. EPA. He has titled his presentation, "Future

irections for Ground Water Protection." Other presenters clude Jay Lehr, executive director of the National Water 'ell Association and Bob Hockman from Amoco Corp. ?presenting API).

EXPOSlTlON The conference is complemented by an exposition.

Leading companies will showcase a variety of equipment and services for preventing, detecting and remediating ground water contaminated by petroleum hydrocarbons and other organic chemicals.

WHO SHOULD ATTEND Ground water professionals from the public and private

sectors will expand their knowledge of monitoring and cleanup techniques. Persons involved in the petroleum industry will find the papers equally a s interesting and informative. Professionals responsible for environmental investigations will learn new methodologies for dealing with hydrocarbons in the subsurface.

Environmental Review

HYDRAULIC CONDUCTIVITY

EDITOR'S NOTE: The following article is taken from Ralph C. Heath, 1987, "Basic Ground-water Hydrology", USGS Water-supply Paper 2220, p12-13.

A Q U I F E R

-- --- -p

(sketch 1 ) Un81 p r r r m o f o g u . l e r

Aquifers transmit water from recharge areas t o dis. charge areas and thus function a s porous conduits. T h e factors controlling ground-water movement were first expressed in the form of an equation by Henry Darcy, a French engineer, in 1856. Darcy's law is

where Q is the quantity of water per unit of time; K is the hydraulic conductivity and depends on the size and arrange- ment of pores and fractures and on the dynamic characteristics of the fluid (water) such a s kinematic viscosity, density, and the strength of the gravitational field; A is the cross- sectional area, at a right angle to the flow direction, through which the flow occurs; and dh/dlis the hydraulic gradient.'

Because the quantity of water (Q) is directly proportional to the hydraulic gradient (dh/dl), we say that groundwater flow is laminar-that is, water particles tend to follow discrete streamlines and not to mix with particles in adjacent streamlines (1).

If we rearrange equation 1 to solve for K, we obtain

Qdl - (M3d-')(m) - m K = - - - - Adh (m2)(m) d

Thus , the units of hydraulic conductivity a re those of velocity ( o r distance divided by time). It is important to note from equation 2, however, that the factors involved in the definition of hydraulic conductivity include the volume of water (Q) that will move in a unit of time (commonly, a day) under a unit hydraulic gradient (such a s a meter per meter) through a unit area (such a s a square meter). These factors are illustrated in sketch 1. Expressing hydraulic conductivity in terms of a unit gradient, rather than of a n actual

gradient at some place in an aquifer, permits ready com- parison of values of hydraulic conductivity for different rocks.

Hydraulic conductivity replaces the term "field coeffic- ient of permeability" and should be used in referring to the water-transmitting characteristic of material in quantitative terms. I t is still common practice t o refer in qualitative terms to "permeable" and "impermeable" material.

T h e hydraulic conductivity of rocks ranges through 12 orders of magnitude (2) . There are few physical parameters whose values range s o widely. Hydraulic conductivity is not only different in different types of rocks but may also be different from place to place in the same rock. If the hydraulic conductivity is essentially the same in any area. the aquifer in that area is said t o be homogeneous. I f , on the other hand, the hydraulic cond~~ct iv i ty differs from one part of the area t o another, the aquifer is said to be hetero- geneous.

Hydraulic conductivity may also be different in different directions at any place in an aquifer. If the hydraulic conductivity is essentially the same in all directions. the aquifer is said t o be isotropic. If it is different in different directions, the aquifer is said to be anisotropic.

Although it is convenient in many mathematical analyses of ground-water flow to assume that aquifers are both homogeneous and isotropic, such aquifers a re rare, i f they exist at all. T h e condition most commonly encountered is for hydraulic conductivity in most rocks and especially in unconsolidated deposits and in flat-lying consolidated sedimentary rocks to be larger in the horizontal direction than it is in the vertical direction

ENVIRONMENTAL UPDATE SEISMIC SHEAR WAVES FOR DISCRIMINATING LITHOLOGY

FROM SATURATION CHANGES by T. L. DOBECKI

INTRODUCTION Generally, mapping the water table in a n unconfined

acluifer is a n ideal and s i m ~ l e task for standard seismic refraction surveying. Typically, the compressional wave velocity variation is less than 500 m/s for the unsaturated medium above the water table to nearlv 1550 m/s at and below the water table, assuming similar &anular media. The refraction method depends upon a n increase in velocity with depth and is most dependable when this increase is significant; refraction would appear to be a "can't miss" method. Unfortunately, a water well may encounter anything from dry, dense till to weathered granite where water was predicted. Thus the notion of a foolproof seismic detection method has some basic flaws.

Saturation versus lithology. The assumption that "a layer having a P (compressional) wave velocity of -1550 m/s is a n indication of the water table may be erroneous." For example, saturated alluvial f i l l has a P wave velocity of 1500-1900 mjs. Unfortunately, weathered sandstone, clay- stone, weathered volcanics, and a host of other materials have the same P wave velocity but d o not represent a water table situation - a n embarassing geophysical dilemma if you were hired to locate a water well.

The preceeding is not intended to serve a s a condem- nation of P wave refraction surveys a s applied to groundwater search. Rather, it is intended to providea rationale for the additional consideration of employing shear waves when dictated by the subsurface stratigraphic situation.

A RATIONALE FOR USING SHEAR WAVES When one merely saturates a granular medium, the P

wave velocity (V,) may increase nearly 500%. Saturation of this same m e d i h has nearlv zero effect on the shear (S) . . wave velocity (V,), however. Shear waves don't care if air or water is occupying the pore space a s long as the skeletal framework of the soil has not been altered. Some even might argue that the S wave velocity would decrease upon full saturation. In either circumstance (zero or negative velocity change with depth), the transition would not be detected by S wave refraction. O n the other hand, a 500% velocity increase between a water-saturated sand and a cemented sandstone may be valid for both shear and compressional waves. This is reflected in the fact that Poisson's ratio for a rock might vary from 0.25 - 0.33 while Poisson's ration for a soil might vary from 0.25 - 0.49 depending upon saturation - a much wider range. As Poisson's ration, a, may be defined in terms of velocity ratio:

where R = (VpjVS), the velocity ratio will be more sensitive to saturation changes than it is to lithologic changes. Therefore, if the problem is discriminating a saturation change from a lithologic change, measuring both Vs and Vp would be a useful diagnostic. Shear wave refraction is the suggested means for finding Vs.

GENERATING AND RECORDING SHEAR WAVES The principal reason S wavesare not used a s frequently

a s P waves in seismics is that they a re not a s easy to create. Generating and recording P waves is, in fact, very easy. Almost any energy source (including shear wave dominant sources) will produce a large amount of P wave energy. Thus explosives, hammers, weight drops, e tc . have all found popularity a s P wave sources. Vertical axis geophones o r even hydrophones in shallow, water-filled boreholes have served well a s sensors to detect the passage of P waves. True, the S wave will be found within these same records, but it is exceedingly difficult to single it out and determine accurate timing of its onset. Two characteristics are found in all so-called S wave recording systems which enable both detection andaccurate timing- 1) they take advantage of the fact that the S wave oscillates in a plane shifted 90" from the plane of P wave oscillation and 2) they try to minimize the influence of the ever-present P waves. The most common means of generating S waves fo r shallow surveys is using a mechanical impact source. This is superior in some respects to explosives in that they d o not produce a large amount of P wave energy along the recording line. For example, Figure 1 (after Schuyler-Rossie, 1987) shows a steel cylinder placed in a shallow ramp which is perpendicular to the seismic line. The geophones are horizontal and their axes a re also oriented perpendicular to the line. Striking the end of the cylinder produces significant S wave energy which travels down the line and produces almost no P wave energy in this direction. The P wave energy travels out laterally away from the line. By then turning the cylinder around and striking in the opposite direction, a n S wave of opposite polarity is

generated. As the minimal P wave polarity should not change, subtracting these two records (one from a blow t o the right; the other from a blow to the left) willcreate an even greater reduction in the P wave while enhancing the S wave. Figure 2 shows one such enhanced S wave recording wherein the P wave is almost absent and the S wave is very distinct. In the shear wave case histories described in the following section, this impact method was employed.

Other meansof generating shear waves include a series of explosive shots; horizontal vibrators, which are used in petroleum exploration; torsional, flywheel powered hammers; and using guns and even mortars shot at an angle to the ground surface. These have sometimes been used for shallow surveys, but the vibrators are too large and expensive t o operate, the flywheel source tends t o self- destruct, and the guns have some safety problems associ- a ted with their use in this manner.

EXAMPLE SURVEY RESULTS During the Summer of 1985, refraction experiments

were conducted at the Colorado School of Mines (CSM) geophysical field camp in southern Colorado in two separate locations. The initial area was well within the San Luis Valley in which several hundred t o several thousand meters of glacial/alluvial fi l l have been deposited by the Rio Grande. This is a classical, ground water table aquifer situation which should be well described by standard P wave refraction. The second, contrasting area was outside of the valley up in the San Juan mountains (volcanics). While shooting P wave refraction data to support a deep seismic reflection crew in this area, the refraction crew periodically noted the presence of a 1500-2500 m/s layer and automatically assumed this was saturated fill resting o n volcanic bedrock. T o verify/dispute these interpretations, combined P and S wave refraction surveys were done in both areas. Figure2, again, shows the shear wave shot record obtained at the alluvial site. P wave records were also generated in these areas using both vertical impacts of a sledgehammer and small explosive charges. Both P wave and S wave data se t s were inverted (interpreted) to produce a layered subsurface model - each layer was given a distinct P and S wave velocity. In some

cases, a layer would show in the P section but not in the S section, a s would be expected if that layer was due to a saturation change.

T o best present the resultsof the survey at the alluvium site, the layered section, based upon the P wave interpretation, is given (Figure 3). Each layer also is assigned a Vp/Vs ratio based upon the analyses of each data set.

FIG. 3 Interpreted cross-section, refraction survey Area 1. Layer parameters are a s follow:

Layer 1: Vp = 303 m/s, Vs = 199 mjs, VpIVs = 1.53 Layer 2: Vp = 712 m/s, Vs = 431 mis , Vp/Vs = 1.65 Layer 3: Vp = 981 m/s, Vs = 715 m/s, Vp/Vs = 1.37 Layer 4: Vp = 1601 m/s, Vs = 715 mjs, VpjVs = 2.24

As shown in Figure 3, several layers are detected. The deepest layer (Layer 4) has the classical saturated alluvium P wave velocity (1601 m/s) but no corresponding jump in the S wave velocity a t that level. The shallower layers, all having a P wave velocity of unsaturated materials, show increases in S wave velocity accompanying their P velocity increases. These upper layers reflect changes in lithology, compaction, o r both. The deepest layer, with no corresponding jump in Vs, must be the true water table. The Vp/Vs ration remains quite consistent at 1.37-1.65 to the base of layer 3 at which point itsvalue increases sharply to 2.24. In this area of thick, unconsolidated materials, the dramatic jump in Vp/Vs indicates the water table.

At the other site, a multilayered subsurface was also encountered (Figure 4) with P wave velocity of the third layer being about what would be expected for completely saturated f i l l (1545 m/s). Is Layer 3 the water table? This layer, however, also is shown to have a change in S wave velocity. The Vp/Vs ratio for the entire stack of layering shows a fairly consistent value (from 1.71-2.00) down to the point a t which obvious bedrock is encountered where the ratio is 1.85. At no point d o we find values appraching the Vp/Vs ratio of 2.24 found for the water table a t the first test a rea . It is judged that the third layer, even though its P wave velocity is that of a classical water table layer, is not a water table but represents highly weathered volcanics.

Layer 1: Vp = 219 m/s, Vs = 109 m/s, Vp/Vs = 2.0 Layer 2: Vp = 718 m/s, Vs = 419 m/s, Vp/Vs = 1.71 Layer 3: Vp = 1545 m/s, Vs = 894 m/s, Vp/Vs = 1.73 Layer 4: Vp = 2963 m/s, Vs = 1597 m/s, Vp/Vs = 1.85

CONCLUSIONS AND A LOOK TO THE FUTURE The addition of shear wave data to seismic refraction

surveys is of significant utility in detecting a water table aquifer and differentiating between water table and weathered bedrock. In addition, as seismic reflection becomes more and more routine for shallow surveys, perhaps shear wave reflection should also be considered in this area. (While the water table is a bad shear wave refractor it is an excellent shear wave reflector.)

Looking beyond this, we must consider other aquifers, for example, fractured bedrock. In thissituation a geophysical sensor which is sensitive to the presence and orientation of fractures is required. Again, it appears that shear waves, now in the reflection mode, will come to the fore. Recent research developments in petroleum literature (Martin and Davis, 1987) have shown how fractured reservoirs impress a shear wave "birefringence" upon waves traveling through such a medium. That is, the shear wave is split into "fast" and "slow" components, which travel through the medium at different velocities, return at different times, and move the geophones in different directions when they are recorded. Recording of shear wave reflections using three- component detectors enables segregation of these various shear waves. This offers potential for determining the distribution and orientation of fractures using surface reflection data. This methodology is at present an expensive and perhaps far-fetched notion for application to ground water exploration, but rapid improvement in acquisition hardware and personal computing power will make such surveys commonplace in the near future.

Regal Rose (Laurentian Rose)

The Texas Commerce Tower is the world's tallestgranite clad building (75 stories). There is enough granite onthe tower to cover eleven football fields (Marsh, unpub-lished). The dark gray stone is called Barre Gray Granite;the pink building stone is Regal Rose.

The Barre Gray building stone is technically a grano-diorite. (The stone industry calls almost allcrystalline rocks"granite.") Barre Gray was quarried in Graniteville,Vermont, from the Barre granite. This building stone isdistinguished by its remarkably homogeneous texture anduniform color.

Regal Rose is a true granite. This building stone wasquarried in Guenette, Quebec, Canada.

The Barre granite is generally considered to be ofigneous origin (Murthy, 1957). The Barre granite wasintruded into schists (Westmore formation) in northeasternVermont. This magma emplacement was associated withmelting of deeply buried sediments during the Acadianorogeny in the mid to late Devonian (Baldwin, 1982; Marsh,unpublished; Murthy, 1957). Later erosion removed theoverburden and glaciation exposed the Barre granite(Baldwin, 1982; Mar$h, unpublished).

Barre Gray building stone is a medium-gray, even-textured rock. The major minerals are quartz, feldspar andmica. The clear to smoky-colored grains are quartz. Thefeldspars, both oligoclase (plagioclase) and microcline(potash feldspar), are white. Biotite is a dark brown mica.Muscovite is the lighter colored mica. Accessory mineralsare epidote, apatite, sphene, and less commonly calcite,magnetite, tourmaline and zircon (March, unpublished;Murthy, 1957).

In the 1800's, Barre granite was quarried for millstones,fence posts and property markers. The extreme hardness,fine to medium interlocking crystals, and uniform color makethe Barre granite a favorite for today's statuary, markers,memorials, monuments and precision surfaces. The hard-ness, beauty and insulating properties make it ideal forbuilding (March, unpublished). .

The Texas Commerce Tower is the tallest buildingoutside of Chicago and New York City. Four of the fivesides of the tower are clad with both granite and glass. Thefifth side is an eighty-five foot span of glass. In addition to theground floor loby, there is the Sky Lobby sixty stories abovethe plaza level.

The sculpture on the Texas Commerce plaza is calledPersonage & Birds by Joan Miro. It is a colorful 55-footbronze and steel structure. The. sculpture is intended toprovide a scene of fun and festivity, in an effort to dispel theall-business atmosphere of downtown Houston (HoustonChronicle, April 1979).

In 1981, inch-and-a-half and three-inch-thick slabs ofsoapstone were trucked some 1500 miles from Schuyler,Virginia to Houston, where they were used as flooring inside

the First City Tower and outside on its extensive plaza. TheTower, a 49-story building with a parallelogram shape,covers the block bounded by McKinney, Lamar, Fannin andSan Jacinto. S. I. Morris of the architectural firm whichdesigned the building says the stone was chosen because ofits warm, dark gray color to contrast with the white,"fluoropon"-coated aluminum walls of the building. BillWaddell, Vice President of uroc. Management Inc., andmanager of the building, is very pleased with the soapstone,noting among other things its ability to take polish well. Hisonly negative comment was that the outside stone canbecome quite slippery to plastic high heels when wet.

Soapstone in the Schuyler area is found in Precambrianrocks of the Lynchburg Formation. According to Greenbergand Milici(1965), the Lynchburg is composed of phyllite andmetamorphosed g'raywacke which contains metamor-phosed mafic igneous rocks. These in turn contain thesoapstone, which has a thickness varying from about 200 to900 feet, and is described as a chlorite-tremolite rock withtalc-chlorite inclusions. The outcrop of the Lynchburgstrikes NNE-SSW parallelling the Blue Ridge Mountains,and soapstone has been quarried in several places along theoutcrop, primarily from Schuyler northward (Greenbergand Milici, 1965). (Soapstone is a massive impure variety oftalc [Mg2Si40100H2]).

This soapstone is known as "Alberene Stone," acontraction of the name of James Serene and AlbermarleCounty. Serene emigrated to Virginia from New England inthe 1880's to begin commercial production from the quarry.

Soapstone has three significant qualities: it 1) is veryresistant to chemicals; 2) is easily cut or machined; and 3)has an unusual ability to take on heat rapidly and to release itslowly. But many people are surprised that soapstone canbe used as flooring, assuming it is too soft or too brittle.However, the stone grades from a soft talc-like rock to aharder chlorite-tremolite rock. The primary minerals fromthe Schuyler soapstone are magnesite and dolomite.Tremolite, magnesite, and dolomite all have a resistance toabrasion or scratching approximating that of a knife bladeor window glass.

Soapstone has had other interesting uses through time.For instance, in the woods around Schuyler one can stillfindshards of bowls carved from soapstone by the Indians foruse in preparing and eating food. When the Europeancolonists moved in, soapstone was quarried for use in theirhomes as fireplace linings, hearthstones, and door andwindow sills. More currently, the stone has been used incounter tops, laboratory sinks, toilet partitions, stair treads,and building facings. (We had a soapstone griddle once, acircular piece of stone about an inch thick with a handle onit!) Because it carves easily, it is also an excellent sculptor'sstone.

The exterior of the First International Bank at InterfirstPlaza (1100 Louisiana) is clad with 7800 tons of polishedSpanish granite (Rosa Porrino) and the sidewalk is unpolish-ed granite. To complement the pink granite, 200,000 squarefeet of rose-tinted glass was used on the 55 story building.When it opened in May 1980, it was the tallest building inHouston (748 feet; Houston Chronicle, 1980). Its uniquelobby is a pyramid of levels rising 7 stories. The interior ofthe building is covered with Roman travertine. The plazafacing Louisiana Street features a colorful fiberglass sculp-ture by Jean Dubuffet. The "Monument to the Phantom" isan abstract townscape with: the Mast, Church, Tree,Phantom, Chimney, Dog, and Hedge (Shriver, 1989).

Rosa Porrino (Spanish Pink) granite is found near Porrino, Spain, about 20 km southeast of the Atlantic coast city of Vigo. This hilly region of northwest Spain is called Galicia and has many granitic and metamorphic rocks that were formed throughout the Paleozoic. Near Vigo, there are two-mica granites, orthogneisses, and two different calcalkaline granites. Rosa Porrino is a calcalkaline granite that has very little fracturing, making it suitable for quarrying into very long faces and large blocks. Its distinct pink color is due to the abundance of coarse-to medium-grained microcline (a potassium feldspar). Other primary minerals are quartz (clear), plagioclase (white, sodium feldspar) and biotite (black flecks). Minor alterations of biotite to chlorite and plagioclase to sericite have been found. Accessory minerals include zircon, fluorite, and apatite (Rey, 1989; see photograph).

The Rosa Porrino formed by anatexis (crustal melting) at the end of the Hercynian orogeny about 300 million years ago (Late Carboniferous). The deep crustal source was Lower Paleozoic sedimentary sequences that were derived from an eroded European Precambrian shield. This and older granites formed as a result of plate movements and intrusion along north-south trending zones of weakness during the Paleozoic. (Priem and den Tex, 1984).

The buff to white Romano Travertine inside the building was quarried east of Rome near Tivoli, Italy. The word "travertine" is derived from "Tibur", the ancient name for Tivoli. This travertine has been used in buildings for over 2000 years, including the Colosseum in Rome (Slagle, 1982). It is a dense rock with abundant cavities, some of which are several inches across.

Romano Travertine deposits are up to 100 meters thick and are being precipitated today. Acidic sulfurous hot springs dissolve carbonate rocks (limestone) around Tivoli and precipitate calcium carbonate (CaC03) as travertine at the surface. It accumulates around tiny bacterial clumps forming laminated mats and bacterial "bioherms," or as ordinary, mud-textured sediment (Folk, 1980).

Other local buildings that utilize this travertine are: Exxon (downtown), MCorp Plaza (Allen Center), One Shell Plaza, Two Shell Plaza, and Jones Hall. (For more information about Romano Travertine, see page 21 of the HGS Bulletin, V. 30, No. 10, June 1988.)

Travertine Romano Spanish Alicante

The exterior walls of the Lyric Office Center a re clad in Travertine Romano Classico, a limestone from Italy. The 26-story building is covered with 130,000 square feet of travertine, clad (or cast) t o a pre-cast concrete backing. Travertine is formed by precipitation of C a C 0 3 from hot spring water. This rock contains numerouscavities o r vugs. Travertine Romano Classico is considered to be Oligocene age. A particular beige color range was specified for use in the construction of the Lyric Office Building. The foyer floor is travertine with the vugs filled to produce a smooth surface. An inlaid, three-inch wide band of Spanish Alicante borders the walls. Spanish Alicante is a pink marble with irregular white calcite veins.

The interior walls a re clad in Verdi Issorie. This is a dark green serpentinized marble. It was quarried in the Vald 'Aosta region of Italy. T h e stone is a metamorphic rock considered to be Jurassic to Cre taceous in age. Verdi Issorie has a coarse-textured brecciated appearance with irregular banded fragmentsin a fine-blocky matrix, separated by thin, irregular, clear to white calcite veins.

The plaza is paved with a flame-finished, grey-green granite; Verde Fountain. This is actually a granodiorite with gray plagioclase feldspar, quartz and patches of green-black ferromagnesian minerals. The granite and travertine are also used in benches around the shrubbery.

Apart from its architectural style, the Lyric Office Center is set off by a unique outside sculpture, Virtuoso, created by a n internationally respected Houston artist, David Adickes. Thirty-six feet tall, it is a representation of a cellist performing and has its own integrated sound system.

HGS GOLF TOURNAMENT A BIG HIT! A good time was had by all at this year's H G S golf tournament! Under perfect skies, a record 420 golfers convened for a day of fun golf, great food, and a multitude of prizes. The

consensus among the participants was overwhelmingly in favor of this year's scramble format, along with the increased number of closest to the pin and longest drive contests, the new putting contest format, and the many door prizes (55). The golfers also seemed to truly appreciate the refreshment cart drivers, not only for their ability to serve drinks, but also for the many golfing hints they freely gave to the players!

The H G S congratulates the more than 180 golfers who captured prizes this year worth over $10,000. Thanks once again t o Kingwood Country Club for hosting this year's tournament and also providing a full course

bar-b-que afterwards. A special thanks also to all volunteers that came out to help. Thanks also to Charlie Gurrola, J r . at Gurrola Reprographics for his time and effort in handling all the art work and

COMMITTEE NEWS FIELD TRIP COMMITTEE Chairman's Column:

With the holidays fast approaching, we find ourselves well into another H G S year. Before you commit your weekends to the joy of Christmas shopping, we would like to offer you a diversion, o r at the very least an excuse to avoid the mall crowds. This month, two excellent field trip opportunities are available. Dr. Robert Grayson of Baylor University is scheduled to lead a trip the weekend of November 10th through 12th, entitled "Carboniferous Geology of the Northern Margin of Llano Uplift, Southern Fort Worth Basin, and ConchoPlatform". This exciting field trip will examine facies and facies relationships, and structural history of Mississippian and Pennsylvannian strata exposed along the northern Margin of the Llano Uplift and in the Colorado River drainage basin. This field trip was originally run by the Fort Worth Geological Society two years ago and received excellent reviews. Although the majority of H G S members work the Cenozoic section of the Gulf Coast , this field trip is highly recommended. The concepts to be studied on this trip should certainly have an application in the younger sediments we explore every day at the office. At $145.00, including most everything, the cost is certainly a bargain and Central Texas in the fall is extremely pleasant a s well as beautiful. For more details, see the detailed advertisement in the September H G S Bulletin, or give me a call.

O n the same weekend, the environmental committee is also offering an interesting trip entitled "Coastal Environ- mental Processes" which will study the Freeport to Galves- ton Island coastal area. For more details see the separate advertisement elsewhere in the Bulletin. See you on the outcrop, MARTIN J . OLDANI Field Trip Committee Chairman

SPECIAL FEATURE

HOUSTON MUSEUM OF NATURAL SCIENCE

WORTHAM I M A X THEATRE OPENS $9 Million Facility Includes Theatre, Restaurant, and Huge Entry Foyer

The newest addition to the Museum, the Wortham IMAXTheatre, named for the principal donor, will open to the public on Monday, September 11. The theatre, located on the west side of the Museum, is a multi-media 402 seat auditorium featuring an IMAX projection system with the world's largest motion picture image.

The Lillie and Roy Cullen Grand Entry Hall will connect the Museum. IMAX Theatre and Burke Baker Planetarium enlarging the Museum complex to approximately 162,000 square feet. There will be a restaurant offering deli sand- wiches, salads and soups and the Museum Gift Shop will be enlarged to include a book room. Museum grounds will be landscaped with walkways, a water feature in the shape of the Texas gulf coast and a giant sundial by which visitorscan tell time. The design team of Hoover & Furr, a 3D/lnter- national Company, designed the theatre and entry addition; Spaw~Glass Builders was the general contractor.

The IMAX film and projection system isa'the cinema of the future" because the size, scope and quality surpasses conventional cinemagraphic methods. The IMAX super 70mm film projection system, focuses on a giant screen 80 feet wide and six stories high-ten times the size of a normal movie screen. I t will be the largest theatre screen within a 500 mile radius o f Houston. The purchase of the projection

system was made possible by a generous grant from the Brown Foundation.

For the movie goer, the attraction of the ]MAX experience lies in its ability to make the viewer feel he is part of the action on screen. ]MAX viewers can almost feel the sensation of weightlessness inside a spacecraft ("The Dream is Alive"), soar over the majestic panorama of the Grand Canyon ("Grand Canyon"), or know the exhilarating experience of rushing 70 miles per hour downhill skiing ("To the Limit").

In addition, IMAX sound has a six-track wrap around stereo system featuring four screen channels and two surround channels. The sound of a rocket blast-off becomes extremely realistic a s the intense sound tapers off when the rocket soars upward. The theatre will be capable of handling live presentations, performances and concerts.

The first feature is "The Dream is Alive," which was filmed by fourteen astronauts on three different shuttle missions. "Dream" boasts unprecedented views of earth from space, dramatic scenes of space walks and their every day activities, from eating to sleeping, in the Space Shuttle. Over 20 million viewers have seen "The Dream is Alive" in fifty-eight IMAX theatres world wide. I t is the most popular of the over 60 IMAX films.

DINAMATION Ill! They're Back ... Again!!

S e e Tyrannosaurus rex snap his toothy jaws and roar! Watch Pieranodon flap his 16 foot long wings and squack! Hear Dimetrodon s tamp his heavy feet! Yes, those lifelike robotic dinosaurs known as Dinamation will again invade the Museum October 19 through February 28. This year there will b e thirteen creatures taking up temporary residence in Brown Auditorium and Jones Gallery. This has been unquestionably the Museum's most popular temporary exhibition attracting a total of 573,000 visitors in the first two live appearances.

T h e dinosaur robots are life-sized creatures that move and growl realistically thanks to computerized pneumatic innards and a foam latex exterior. Set in a eerie, mist-filled swamp, the noisy monsters take you back in time to the mesozoic era-between 65 and 225 million years ago- before man even existed. It's history, science and fun rolled into one!

There will b e a special charge for this exhibit in addition to regular Museum admission: $2.50 for non-member adults ($2.00 members) & $1.00 ($.50 members for non-member children 11 & under.

"DEATH OF THE DINOSAURS"

About 65 million years ago, dinosaurs suddenly vanish- e d from the face of the Earth. Their existence was hidden from man until a chance discovery of a large fossil in Great Britain in the middle of the 19th century. Since then, man has discovered over 250 types of dinosaurs. However, the more man learns about dinosaurs, the more mysterious their existence becomes. The greatest dinosaur mystery of all is why they all died off suddenly.

T h e Planetarium is presenting "Death of the Dinosaurs" a special program devoted to exploring the causes of this mass extinction. The program focuses on changes in the Earth that could have been responsible for the "Death of the Dinosaurs."

"Death of the Dinosaurs" will run from October 6-February 25, but will not b e shown November 24- December 3 1.

Book Review T H E FEELING OF F I N D I N G OIL

by Jay E. Valusek

A review of Oil Notes, by Rick Bass (1989). 172 p. Published by Houghton Mifflin/Seymour Lawrence, Two Park Street , Boston, Mass. 02108. Price, $16.95.

O n e blast-furnace day when 1 was ten, I f reed a Mississippian crinoid from a dusty Kansas outcrop with my own rock hammer and chisel. Dripping sweat in the dirt, oblivious to the sounds of other children chinking around me. I sa t transfixed by my discovery. All I could think was: 300 million years ... That sense of awe in the presence of the earth never left me, which is why 1 eventually became a geologist.

Oil Notes, my latest geologic discovery, is filled with awe. Rick Bass, petroleum geologist and writer, has captured that feeling-of being a geologist; in particular, of finding oil. I judge that he has done the profession great gobs of good. In the 70's, the public learned to view petroleum geologists with suspicion; in the go's, with pity (at least here in Houston). Now Bass offers a different perspective. A fresher, more personal one .

"1 know how to find oil," he writes. And he wants to tell u s what it feels like t o know where oil is in the ground, but (he claims) he's not su re how to d o it. Believe me, he's lying. He admits a s much o n page 165: "They're not alike at all, really: writing and geology. There's a deceit in writing ... Basically, ~t 's building a lie and then swinging the lie's nlassiveness into the path of the reader and hiding behind ~t ." Only, in thiscase, the lie hits the payzone. You read this massive little book, and you know what it feels like. T o find oil.

How does he d o it? If you ever a te catfish at a roadside inn, o r loved a girl

named Elizabeth, you know. Written a s a journal in odd, impressionistic bits ("little scratch notes", he calls them) at well sites, in the office, o n his farm, Oil Notes turns ordinary things into geological metaphors. His relationship with Elizabeth, for example, mirrors the uncertainty and joy of the quest for oil. O r perhaps I've misunderstood, and geology is the metaphor for Elizabeth. You decide.

In case you haven't heard of Rick Bass, you ought t o know that not long ago his book of short stories, The Watch, received favorable reviews in high places, including the New York Times. In Oil Notes, Bass maps the boundaries o f hislife a s an independent petroleum geologist with the same literary deftness, proving art and geology flow from a common reservoir. T h e son of an oilman, Bass has i t in his blood. Red Smith once said, "There's nothing to writing. All you d o is sit down at a typewriter and open a vein." When Bass bleeds, he produces oil.

Take a look a t some sample cuttings from this discovery: Besides catfish, Cokes , baseball, bullies, abandoned dogs, and of course, Elizabeth, Oil Notes explores the Black Warrior Basin, the meaning of wildcat wells, development geology ("Forgive my ego, but I like it better than the job of exploration geologist [the other kind]"), directional drilling (you can reach oil under O n e Shell Plaza from the nearest vacant lot), the carbon cycle, "big-company" geologists, environmental pollution ("I hate coal"), well logging ("I love to log wells ... No one has ever before seen what I am seeing"), leases and mineral rights, coring, frosted

sample jars ("It is great to hold the oil that you have found in the field in your hand"), the oil glut, geologic time, skin damage (not his; a well's), dry holes, dreams ("Someday I am going to drill my own wells"), and selling prospects ("Look: you can't ever sell me o n a prospect if you g o and use a word like 'scenario' ... The word implies a condition, and 'if'. 'Let's assume the following scenario'? Sheee-yit. Let's don't ... Tell me where oil is. And why. Then if we're wrong, we lose").

In a leisurely 360-degree camera sweep of his office, every oil finder will recognize familiar terrain ("Directly behind my desk, the drafting table, the battlefield ... Some- times the maps are layered on my desk, like the rock formations beneath the ground"). But remarkably, Bass isn't writing for us, for geologists. He's writing-wisely-for a much larger audience: folks who enjoy a good read. It's immensely satisfying that someone should render ou r profession in such palatable terms. 1 cannot help but think of J o h n McPhee, staff writer for The New Yorker.

Like McPhee, Bass writes from inside the geologist's skin. Unlike McPhee, the skin is his own. Also unlike McPhee-whose three books o n geology and geologists a re typically stocked ( i f anywhere) under "M" in the Literature section of bookstores, s o you have to be looking; you're unlikely t o stumble on them-Bass's book is stocked under Science (at least at The Bookstop). Probably because it has a n oil rig on the cover.

But don't get lazy. Buy a copy now, before they realize their mistake, and file it under Literature. Who knows what might happen to it over there.

About the Reviewer: Jay E. Valusek is a geologist/writer with Landmark

Graphics Corporation. He has published numerousarticles o n computer-aided exploration (CAEX) applications and trends in the oil industry. He holds an M.S. in geology from Colorado School of Mines, and previously worked as a development geologist for Pennzoil Co .

PERSPECTIVE

STATUS OF TEXAS REGISTRATION DPA President Issues Call for Participation In Model Bill

by DAN SMITH and THOM TUCKER The original Texas registration bill was sponsored by

the Association of Engineering Geologists and was intro- duced in the 1988-89 Legislature. There is a definite need for registration of Engineering, Hydro, and Environmental Geologists. However, the need for state registration of Petroleum Geologists is very questionable. While the latest bill to register geologists has been pulled, it will b e back! If we are to exempt petroleum geologists from anything but voluntary registration, we must be involved in the legislative process. According to Pat Gratton, newly installed Presi- dent of the Division of Professional Affairs (DPA) for the AAPG, the policy of resisting all registration efforts no longer works. Mr. Gratton made these and other remarks to Houston DPA members at a luncheon on 25 August 1989.

Clearly, registration is a multi-state issue in which Texas will play a leading role. Late in August, Lyle Harvey of the New Orleans Geological Society reported that a draft bill for the registration of geologists existed in Louisiana. Dan Titerle's article in the August 1989 EXPLORER, while reviewing the status of registration efforts in the several states in which such bills are being considered, served to focus attention on Texas. Using slides, Mr. Gratton illustrated that currently 15% of AAPG members live in states which have some sort of registration. However, with Texas included. this would increase to over 50% of domestic AAPG members (see Fig. I ) .

AAPG Members Subject to State Registration (Illustrating Effect of Texas)

Figure 1.

With such a large percentage of members potentially affected, the DPA must get involved, Mr. Gratton said. We have the option of influencing legislation, but not stopping it. "Most of the time where the DPA has simply opposed any sort of registration bill, we've lost. Our wins have been temporary; our losses have been permanent." Organiza- tions such as the Association of Engineering Geologists are

committed to introducing bills for the registration of engineering geologists in every state where there is none, and to strengthening those bills which already exist. These bills always get altered by legislatures to include all geologists. The AAPG through the DPA "needs something to run with" that is designed to minimize the impact on the petroleum geology profession. Representatives of other societies have indicated their willingness to co-operate.

In the Fall of 1988, the DPA Advisory Council adopted the policy of working to develop, in liaison with other professional geological societies, a "model bill" for the registration of geologists which exempted petroleum and minerals from mandatory involvement. At the luncheon, Mr. Gratton presented a list of key elements which the DPA Executive Committee concluded were essential i f a model bill were to be acceptable to petroleum geologists:

1. Grandfather clause with a reasonable time limit. 2. A reasonable test. 3. Voluntary exemption of Petroleum and Minerals

Geologists from Mandatory Registration. 4. Minimum Experience and Education Require-

ments. 5. Ethics and Morals Clause(s). 6. Reasonable Fees. 7. Comity (reciprocity between states). 8. Fair Board Composition (proportional representa-

tion on the board). 9. Specialty Recognition.

10. Reasonable Penalties. Mr. Gratton has arranged to bring together the senior

officers and state registration committee chairs from each of the concerned professional societies for a November meeting in Dallas. The goal would be to establish guidelines acceptable to the membership of each organization.

Ultimately, a model bill needs to be drawn up and presented to the Executive Committees of the concerned societies for endorsement. Remember, other state legislatures are in session all year! Skip Hobbs and the AAPG Committee on State Registration (Dan Titerle is the Texas and SW region representative) are working with Pat Gratton to accomplish this objective before the June 1990 AAPG Convention in San Francisco. Comments and suggestions are being sought. Your ideas and offers of assistance may be addressed to:

PERSPECTIVE

GALVESTON BAY AS A SEAFOOD FACTORY

by ROBERT W. McFARLANE, Ph.D.

Galveston Bay is many things to many people. To the mariner, it is a place to float your boat, be it dinghy or ocean-going tanker. To the fisherman, it is a seafood factory where you tow a shrimp trawl or cast baited hook. This seafood factory is dependent on the input of raw materials and a hospitable habitat to produce its products, both shellfishes and finfishes.

In this era of lite-bread and lite-beer, the'bay contains "lite-water", containing less salt than seawater from the Gulf of Mexico. An estuary is, by definition, an embayment where freshwater from the land dilutes seawater. Both horizontal and vertical salinity gradients exist. Upper Trinity Bay may be 0-5 ppt (parts per thousand) salinity on the surface but 5-10 ppt on the bottom, even in only 3-4 feet of water. The center of the bay may be 15-20 ppt, and 25-30 ppt at the bay entrance, or even a short distance into the gulf, which is normally 34-35 ppt. In deeper bay water, and the ship channel, the vertical differential may be 15-20 ppt between surface and bottom.

The horizontal and vertical salinity gradients are highly dynamic, affected by freshwater inflow and winds. In natural and man-made channels, currents may flow in opposite directions, as freshwater moves seaward at the surface and denser seawater creeps upstream on the bottom of the channel. The dynamic equilibrium can be upset by either a reduction in freshwater inflow or an increase in saltwater intrusion. Galveston Bay is threatened with both calamities.

Many principal commercial and recreational species actually reproduce in the open Gulf of Mexico. Their larval and juvenile forms are passively transported into the coastal estuaries by near-shore currents and tidal exchange. Once in the bay, these young creatures prosper in the nutrient- rich brackish water available in and near peripheral wetlands. The vital freshwater inflow performs three functions. It provides freshwater whichdilutes the seawater. It transports the dissolved and particulate nutirents which nourish the organisms. It transports the sediments which maintain the delta marshes that provide sheltering habitat for the biota. Thus the critical raw materials needed by the seafood factory are freshwater, nutrients, and sediment from land and marine organisms from the sea.

The plan to enlarge the 40 ft deep by 400 ft wide Houston Ship Channel to 50x600 ft will double its cross- sectional area when the 2.5: 1 sideslope area and additional 5 ft of "advanced maintenance" depth (to 55 ft) are considered. Thus the saltwater wedge pushing upstream will increase substantially. Although the Corps of Engineers predicts that salinity increase will be less than 1 ppt, its predictive model is 2-dimensional, uses one-square-mile cells, and fails to accurately portray existing conditions.

Furthermore, it appears that no one has ever measured the fine-grained, cross-sectional, salinity gradient of the existing channel. How deep is the salt water wedge? How far does saltwater from the channel spread laterally, up the slope and across the bay bottom? What is the effect of large ship propellers, which visibly raise bottom sediment to the surface, on mixing and dispersing the denser salt water? Since the channel crosses the heart of the best oyster reefs, bottom salinities are critical. Oysters do best in 10-20 ppt water. Lower salinities reduce their fecundity; higher ,salinities give their predators and parasites the competitive edge, reducing oyster survival.

Dredging operations will resuspend toxic substances attached to sediment particles, especially clays. Open-bay spoil disposal will cover thousands of acres of productive bay-bottom habitat. Wind, wave, and tidal action will disperse spoil beyond its designated boundaries. Toxicants will be subject to transport, transformation, bioaccumula- tion, biomagnification and synergistic activity in the food web, which includes man.

When the freshwater needs of Galveston Bay are considered, the chosen site of the Wallisville Dam, at River Mile 4, is the worst possible place to construct an impoundment, for there is no additional watershed downstream of the damsite. Proponents of the Wallisville Dam have assumed that the 5,600 acre reservoir, topping out at 4 ft above sea level, would barely influence river discharge a

reaching Trinity Bay. Lake Livingston, at River Mile 129, and Wallisville Lake

were designed to operate as a system. An assessment of potential environmental impact must consider the combined impact of the Livingston-Wallisville system. The greatest impact will not occur under conditions of high flow or even average flow. The impact will be maximum under conditions of low regional precipitation, when river discharge is low and both the estuary and residents of Houston most need the water.

Annual Trinity River discharge, as measured by the U.S. Geological Service gage at Romayor, ranges from 917,300 to 12,280,000acre feet (Fig. 1A). It is subject to rapid change; for example, the record low of 1956 was followed by the 2nd highest flow in 1957. The flow is seasonally unbalanced (Fig. lB), with summer, from July to October being the period of greatest environmental "crunch". Single precipitation events, accompanying tropical depressions, storms, and hurricanes, significantly skew average monthly discharges toward high values. The geometric mean averages 40 percent less than the arithmetic mean monthly discharge but closely approximates the median value (Fig. lC), indicating that less water reaches the bay than previously believed.

At some point in the future, water right holders will simultaneously withdraw their full allotments, since water allotments already exceed average discharge of the river. When the authorized water rights of the City of Houston, Trinity River Authority, and 3 irrigation systems downstream from Lake Livingston, are compared to various historic low flow levels, the potential impact of the Livingston-Wallisville impoundment system is revealed.

i Houston Geolog~cal Soc~ety Bulletin, November 1989 38

The median, 1st quartile, and 1st decile flows represent the discharge historically experienced during the lowest 50%, 25%, and lo%, respectively, of years since 1925. Net flow is determined by subtracting the seasonally adjusted, maximum authorized withdrawal from monthly median, quartile and decile values. Figure 2A shows that zero flow may occur from July to October, with low flow in November, every other year. Low flow in June, and zero flow from July to December, may occur once every four years (Fig. 2B). In

one year of every ten, zero discharge will prevail all year, except for a low flow during May (Fig. 2C). This amounts to virtually turning off the Trinity River tap, and half of the bay's freshwater supply comes from that single source.

Galveston Bay is thus threatened with a devastating one-two punch. Complete utilization of the already authorized water yields of Lake Livingston, Wallisville Lake, and three irrigation systems on the lower Trinity River will severely impinge freshwater inflow to Galveston Bay. River flow may cease for four to twelve months a year. Enlarge- ment of the Houston Ship Channel may double salt water intrusion into the bay, further increasing salinity levels. As a result, salinity in the bay may reach levels detrimental to estuarine finfish and shellfish productivity. The seafood factory may even experience a layoff of commercial and recreational fishery workers, extending our analogy one further step. In Galveston Bay, as elsewhere, everything is indeed connected to everything else. It remains impossible to do one thing.

Fracture Identification and Geomorphic StructuresApplied to Hazardous Waste Disposal and

Other Environmental Projects.

SANTIAGO M. REYNOLDS-Biographical Sketch

Santiago is presidentof Sanco & AssociatesInc., a consulting firmspecializing in the con-struction and applicationsof Geomorphic StructuralInterpretations and Frac-ture Identification Mapsfor Oil, Environmental,and Construction in-dustries. He has mappedmany areas in the UnitedStates and overseas.

Santiago is a 1959graduate of MidwesternUniversity in Wichita Falls,

TX. He worked many years for Pemex and later for Gulf andAminoil before Keplinger and Associates brought him toHouston in 1978. Since 1982 he has consulted as Sanco &Associates Inc. in many drilling projects using the fractureidentification on geomorphic structural maps as tools inorder to have a better understanding of geologic features.

He is a Certified Professional Geologist #4890, aCertified Petroleum Geologist #2075, and a member of theAAPG, AIPG, and HGS where he has served since 1983onthe Awards Committee.

APPLICA TIONSThe identification and effective application of fracture

patterns has been proven in the oil industry, in terms offracture porosity or fracture permeability. They are amedium through which -hydrocarbons, or any other fluid,can easily migrate. It is critical to recognize the fractureconcept as responsible for the development of otheranalytical techniques, such as soil geochemical analysis,micromagnetics, and radiometrics. Other tools and tech-niques also depend on fracture patterns in order to collectand register their signals.

Experience obtained in the oil industry through theidentification of fracture patterns in conjunction with thegeomorphic structural interpretation has resulted in practi-cal applications with beneficial effects. The concept is nowapplied more precisely in other industries, where its usedeals with geologic features more closely related to surfaceforms. Our main concern here is environmental projects,but other projects that can utilize fracture pattern identifi-cation study include Disposable Waste Sites on the surfaceor subsurface and their remedial problems, WaterManagement, and Construction of Atomic or IndustrialPlants.

VERTICAL MIGRATIONRain water and/or other surface fluids percolate

through soils, clays, shales or any other supposedly imper-meable layers (leaky confining beds) through fractures.


l

Deep-sourced fluids found on the surface have traveledthrough fractures. Surface fluids also can percolate downthrough impermeableor confiningbeds.Both directions ofvertical migration may be a function of hydrostatic andlithostatic confining pressure.

During the last 20 years considerable efforts have beenmade toward reaching an understanding of vertical migra-tion through fractures, and their influence, patterns, be-havior and practical applications for the petroleum industry,environmental, industrial and urban development.

TECHNIQUESAfter we accept fracture influences in our projects, we

next face the problem of how best to identify and map themin the field. Different techniques have been used: Surfacegeology, geophysics, coring and remote sensing. Photo-geology and satellite imagery are the most cost and time-effective methods. Once mapped, surface verification in thefield is advised.

A good first step at locating fractures at the surface is touse remote sensing tools. After this, we select stereo highaltitude photographs for much greater detail. As an ex-ample, on a typical evaluation of 100 square miles, Landsathas been used at a scale of 1:100,000. Sixteen fracturetraces were recognised through the specific area. WithLandsat at 1:50,000, 33 fractures were recognised. Usingthe stereo pair photographs as a final stage, over 300fractures were mapped. The two Landsat images showregional fractures, some over 30 miles long, while the aerialphotographs provide excellent resolution needed for localfracture mapping.

COMPLICATIONSVertical migration of fluids is discussed above, but

there is another type of fluid movement: horizontal migra-tion through dipping fractures. This migration is controlledby the dip of the bedding in a structure relative to theattitude of fractures in those beds. A topographic map givesan idea of the general drainage direction in an area. Ageomorphic structural map, interpreted from a topographicmap, with fractures identified, will provide detailed infor-mation on possible horizontal and vertical fluid migrationpaths. These may be different from the surfiice runoffdirection.

Combining fracture identification with geomorphicstructural mapping, hydrology, and subsurface geologyleads to good subsurface models to help in the selection ofstorage sites, and should prove useful in executing remedialwaste cleanups.

Let's contemplate the risk of spreading contaminantsfrom an old hazardous waste dump, very close to an urbandevelopment (Fig. 1). This hypothetical example showssome "hidden possibilities" for contaminants to migratehorizontally and/or vertically through fractures. In thisparticular example we postulate that all conditions werehighly favorable for the migrating hazardous waste to moverapidly to the urban area. A fracture identification map

40

indicates the existence of abundant local and regional fracture patterns, dissecting the site in different directions (Fig. 2). The geomorphic structural map shows this site is located in the middle of a small, oval, anticlinal structure. A topographically flat surface is assumed.

INTERESTED EMPLOYERS, PLEASE CONTACT BULLETIN EDITOR

If we look carefully we notice that ~ r ev ious corina and u

soil samples have been collected through the last 15 years without encountering any serious contaminant horizontal migration (Fig. 1). The monitoring procedure was correct before local and regional fracturing patterns, and the anticlinal structure, were known. Soil samples and cores along the fracture traces might show that the fracture zones were invaded vertically and/or horizontally by the contaminants. In addition, it would be possible to show whether the contamination is advancing horizontally along the fractures, opposite to surface runoff, already invading the nearby urban development (Fig. 2).

If a strongly contaminated horizontal-vertical fluid migration is in fact taking place, the fluids may be traveling downdip in the near subsurface, along the fractured zones toward the structural lows represented by the geomorphic closure that delineates the masked anticline. The pattern of migration is likely to be radial. A contaminated site with regional and local fractures on top of a structural nose or anticline increases the risk of spreading such contaminants outside the site area and deeper into the structure. Migration patterns, width and depth of open fractures, timing and migration rate of fluids are all erratic, and analogous examples are rarely valid. Every fracture pattern should be treated as an individual case, and fluid behavior should be studied at every site. The remedial procedures are easier to implement if we know the possible fracture zones and their geologic and geographic arrangements.

Texas Gulf Coast Yucca Oil will drill a 6500' Wilcox test 1-314 miles east

of Edwards and Wilcox production at Henry Field in McMullen County. The #1-B Lester-Powers Ranch is2000' southwest of the operator's #1 which penetrated the entire Wilcox section before abandonment at TD 6510'. Wilcox structure here is irregular southeast regional dip with some small scale faulting present in the area.

Farther north, in the southeastern corner of Medina County, Shafer Oil has staked a 6000' Sligo test 3 miles northwest of San Miguel and Anacacho production at Benton City South Field (Atasosa County). The #1 Morales Unit is 3 miles northeast of a 5000' Sligo dry hole (Hughes & Hughes #1 Plachy) which took numerous cores between 4377' and 5000' but recorded no hydrocarbon shows. About 3000' southwest, the Shafer #1 Blatz was just completed as an Anacacho discovery, flowing 167 MCFGPD from 1876- 1905'. Structure at the Edwards "A" horizon is regional southeast dip with local nosing.

A 5500' Edwards test will be drilled by United Oil & Mineral 1-1/2 miles northwest of Austin Chalk, Buda and Georgetown oil production at Stockdale East Field in Wilson County. The #1 Abigail is also 1-1/2 miles west of Anacachooil production at Kelly Lynne Field. Stockdale NE Field, 3-1/2 miles northeast, has an Edwards pay at 5166'. Structure at the base Austin Chalk is moderate southeast regional dip.

R. H. Engelke will drill a 9400' Frio test 1-1/3 miles southeast of Frio production at La Ward North Field in Jackson County. The #1 Clemens, et al will evaluate deep Frio sands and possibly thin stringer type Vicksburg sands near TD. At the Textularia mississippiensis horizon the wildcat appears to be located on a broad structural anomaly probably related to the La Ward shale ridge.

Farther north, in Colorado County, North Central Oil has staked a 7450' wildcat 1-314 miles southeast of Mohat Field (Wilcox production) and 2-314 miles west of Chester- ville North Field (Miocene and Yegua).

production at West Starks Field in northwestern Calcasieu Parish. Initial production at the Prairie #1 Hankamer, last year's discovery well for West Starks Field, was 8,865 MCFGPD and 1,059 BOPD. At the Hayes horizon the wildcat spots on southeast dip and downthrown to a local down-to-the-south fault.

Also in Calcasieu Parish, Triad Energy has staked a 9999' Hackberry wildcat 2-1/2 miles northwest of basal Hackberry production at the old Edgerly Field. The #1 Baggett is about 3000' southeast of a 12,110' dry hole (Exxon #1 LaBokay) drilled in 1986. A't the Hayes horizon the new test spots on irregular south dip, separated from Edgerly Dome by a broad saddle.

Farther east, in southwestern St. Martin Parish, Quintana Petroleum will drill a 13,000' Discorbis (lower Miocene) test 1-1/2 miles east of Marg tex (Frio) production at Cade Field. The #1 Yeargain is also 3-1/2 miles north of Quintana's Coteau Field discovery (#1 Dore), completed last year from the Alliance sand (upper Oligocene) for 2,211 MCFGPD and 16 BCPD. At the Camerina 'A'horizon the wildcat spots on moderate southwest dip, immediately downthrown to a down-to-the-basin fault.

A 15,000' lower Tuscaloosa wildcat, the #1 Kinchen Estate, has been staked by the Baruch-Foster Corporation 5 miles northeast of Wilcox production at Steward Branch Field in Livingston Parish. Lower Tuscaloosa structure here is southwest regional dip with broad, subtle nosing.

MESOZOIC TREND East Texas

Lasmo Energy will drill a 10,200' Glen Rose test in southwestern Houston County 4 miles northeast of Glen Rose production at Alabama Ferry Field (Leon County). The #1 Edwards is about 1-1/2 miles southeast of a 10,100' dry hole (Cambridge #1 Potter) which recovered salt water from the Woodbine and a slight show of oil and gas from the Glen Rose "B". Structure at the top Glen Rose "B" is regional southeast dip.

In far western Navarro County, Wadsworth Oil will drill a 3300' Rodessa wildcat 14 miles northeast of nearest production (Woodbine) at Hubbard Field. The #1 Cora Moore, e t a1 is about 4300' northwest of a 2774' Rodessa dry hole (Wadley #1 Cook) which reported no cores or tests. Structure at the base Massive Anhydrite is regional east dip.

Murphy Oil USA has staked a 6500' Paleozoic test in western Bowie County, 9 miles northeast of Smackover production at Megan Field in Red River County.

In southwestern Covington County, Alabama, BHP Petroleum (Americas) has staked a 13,500' Norphlet test 2 miles northeast of the town of Bradley (in Escambia County). The #1 BHP/Edge-Henley is about 1-1/2 miles southwest of the Cox #1 Paramount-Jeffers, completed earlier this year from the Haynesville, flowing 478 BOPD and 26 MCFGPD from 13,011-056'. Closest previous Haynesville production is 50 miles northwest in Frisco City Field, Monroe County. At the top Smackover horizon the wildcat spots on local west dip, which could be masking a small basement structure.

INTERNATIONAL HIGHLIGHTS EUROPE Germany (Onshore)

ITAG announced a gas discovery at the Paepsen Z-1, a wildcat located in the Staffhorst permit in the Lower S a x o n y basin, northern Germany. The Permian Stassfurt carbonates yielded 5,085 MCFD of sour gas with a high water-cut on test.

Norway (Offshore) Norsk Hydro has successfully tested the 3519-1 wildcat

north of Troll Field.. The oil zone flowed 5,680 BOPD (42" API) and 9,060 MCFGPD, while the better of two testsin the gas zone yielded 32,243 MCFGPD and 1,124 BCPD, all tests being in the Middle Jurassic. Norsk Hydro plans a 3-D seismic survey on the structure before drilling an appraisal well scheduled for next year

United Kingdom (Offshore) The Ultramar 29/5B-6 appraisal well, located in the

newly-named Franklin Field, reached a new record depth for northwestern Europe offshore areas at 19,010'. The well tested up to 29,000 MCFGPD and 3,510 BCPD from the main zone; with three other zones yielding a combined 23,000MCFGPD and3,180 BCPD. All tests were conducted below 17,000',

NEAR EAST Oman (Onshore)

PDO reported two oil discoveries in June. In central Oman, not far from the Qarat al Milh 2 discovery of 1987, the Hadlyah 1 wildcat encountered an oil zone prior to reaching its 3165 m (10,384') TD. In southern Oman, PDO has an oil discovery at the Gharibah 1 wildcat located 10 km (6.2 miles) WSW of the 1981 Mukhaizna S 1 oil discovery. TD was 1300 m (4265') in the Paleozoic.

AFRICA Angola (Offshore)

Cabinda Gulf has another oil discovery in the offshore Cabinda concession (Lower Congo basin) at their 104-1X wildcat which yielded an undisclosed amount of oil, possibly from a sandy section in the Albian Pinda formation, before being suspended at TD 4535 m (14,879'). Location is about 9 km (5.6 miles) NNW of the N'Dola structure, apparently along the same trend.

LATIN AMERICA Brazil (Onshore)

Petrobras completed the 1-CUP-1-AM (Cupiuba) as a

gas/condensate discovery in the Upper Amazon basin. Flow rate was 5,100 MCFGPD and 200 BCPD from 2475-80 m (8120-37'), possibly in the Upper Carboniferous Monte Alegre formation.

Ecuador (Onshore) The Danta 1 wildcat, drilled by British Gas in Block 12,

tested 1,015 BOPD (19" API) from the Lower Napo "T" sands, and 919 BOPD (17.2" API) from the Cretaceous Napo Lower "U" sands. This is the third of four commit- ment wells and follows two disappointing wildcats, Tigrillo 1 and Mantal 1. both abandoned with shows.

Peru (Onshore) Petroperu has completed the Chambira Este 123 as an

oil well, flowing an aggregate of 5,680 BOPD from two zones in the Cretaceous Chonta formation. The well is located in the western portion of the block and east of an area which was explored by Getty in 1974.

FAR EAST India (Onshore)

ONGC's Andada-1 wildcat, located in the Cambay basin in western Gujarat, tested an aggregate of 1,250 BOPD and 124 MCFGPD from two pay zones in the Eocene Kalol formation. Further testing is in progress.

ONGC's Adlyakkamangalan (ADK)-1, located 260 km (161 miles) SSW of Madras in the Cauvery basin, flowed 615 BOPD (40.9" API) and 3.5 MMCFGPD from two horizons between 2011 and 2381 m (6598-7812') on initial tests. Production testing is now in progress.

Malaysia (Onshore) The Japanese firm Baram Oil Development Co. made a

significant oil discovery at its second wildcat in Block SK 14, onshore Sarawak. The Asam Paya 1 flowed an aggregate 5,450 BOPD (37"-44" API) from eight zones between 1500 and 2100 m (4921-6890'). The well is located in northeastern Sarawar, near the Brunei border.

Pakistan (Onshore) OGDC announced that their Pasahkl 1 wildcat in the

Sanghar PL tested 2,600 BOPD (43" API) and 790 MCFGPD from a 19 m (62') section of the Lower Goru formation. Location is 17 km (10.6 miles) north of OGDC's Thora Field in the Indus basin.

Occidental announced a new oil and gas discovery at its Soan block in the Bannu-Potwar basin. The Bhangali 1 flowed 3,110 BOPD (32" API) and 7,200 MCFGPD from perfs at 3665-3761 m (12,025-12340') in the Eocene Sakasar formation. The well is located 13 km (8.1 miles) north of P.PL's Adhi Field and 52 km (32.3 miles) east of Occidental's Dhurnal Field.

I Get rapid quantitative identification of

I minerals, including clays, with Mineralog

Rapid, cost-effective, and accurate Core Laboratories' MineralogTM, a quantitative identification service using Fourier transform infrared spectrometry, is faster and less expensive than traditional methods of identifying minerals. It is accurate to +5 weight percent.

Data you need when you need them most Mineral data are critical, influencing everything from log calibration, to the selection of drilling and production fluids, to control of formation damage. Mineralog analysis can be performed in a well-completion time frame and is suitable for conventional core, sidewall core, and drill cuttings. These measurements

not only provide quantitative data for cali- brating wireline logs, they provide a thorough mineral characterization of the well selection.

"The best thing to happen to sidewall core analysis in the last fifteen years" That's what an exploration geologist with a leading major called Mineralog. We call it The Interpretive Edge". Let us give you the Edge on your next well.
