The new exploration impetus pro-vided by market-oriented reforms in Bra-zil has had a dramatic impact on newseismic data acquisition over the last yearor so. This new acquisition phase hasextended out into the deepwater off-shore regions. In the Gulf of Mexico,the shelf region has been extensivelycovered by 2D and 3D data. In recent

years this coverage has also extendedoff the shelf and into the deepwater.

In Brazil and the Gulf of Mexico,state-of-the-art seismic data acquisitionand processing, both onshore and off-shore, is dramatically improving dataquality and reducing turnaround times.Extremely long streamers, up to 10 kmlong, large acquisition footprints and pre-stack time migration with higher-ordernormal moveout are now being increas-ingly employed.

This study compares five deepwaterfields, Mars and Diana in the Gulf ofMexico and Roncador, Marlim andAlbacora Leste in the deepwater Cam-pos Basin, offshore Brazil. From largeregional recently acquired 2D and 3Ddatasets the regional structural frame-work can be compared between thesetwo regions as well as the seismic ex-pression of the reservoirs themselves.

The main reservoirs of the offshoreBrazil deepwater examples are in shelfderived turbiditic sands with mound ge-ometry. This stratigraphic trappingmechanism is structurally augmented by

large listric faults, which can fault boundthe reservoirs, and also by salt with-drawal. The Gulf of Mexico deepwaterexamples occur in generally youngerlowstand reservoirs of Plio-Miocene agein combined structural/stratigraphictraps involving pinchouts against salt-bounded minibasin flanks. In addition,the confining nature of these salt-bounded minibasins can allow significantreservoir stacking.

In all of the offshore Brazil fieldexamples stacked turbidite sands withhigh porosity and permeability are acommon characteristic of the reservoirs.Oil-bearing sands are encountered in theUpper Cretaceous, Eocene, Oligoceneand Miocene sections. In many instancesthe oil and gas lowstand reservoirs pro-duce high amplitude hummocky reflec-tors. In addition, bright spots, flat spotsand AVO effects have also been identi-fied seismically. In the Gulf of Mexicofield examples relatively well resolvedseismic images showing good seismic

delineation of channel levee complexesand basin floor fans can often be seenin the minibasins containing these fields.Seismic sections across the Mars andRoncador fields are shown.

Salt plays an important role in thepetroleum system of both regions. Inthe Santos and Campos Basins autoch-thonous salt generally thickensbasinward. In the Gulf of Mexico salthas reacted to the sediment overburdendifferently in that extensive detachmentof salt from its original stratigraphic po-sition occurred forming a huge mosaicof amalgamated allochthonous canopiesand associated minibasins.

There also seems to be differencesin the nature of the migration pathways.The Brazil field examples are all associ-

ated with large listric or planar faults thatbreach the autochthonous salt in ‘win-dows’ between massive salt, i.e. in re-gions of primary welds. Migration canoccur up these faults and into the over-lying reservoirs. Hydrodynamic migra-tion directly from the syn-rift to the res-ervoir is possible in areas where thereare no salt structures.

GEOPHYSICAL METHODS FORENGINEERING AND ENVIRON-MENTAL SITE CHARACTERIZA-TION

Mustafa Saribudak, Ph.D.Principal Geophysicist

The primary factor affecting theaccuracy of any site characterization ef-fort is the limited number sampleborings, resulting in insufficient spatialsampling to adequately characterize thesite. This is the primary reason for theapplication of surface geophysical meth-ods.

There are a number of geophysicalmethods that are commonly applied todetailed shallow depth investigations.These methods are described as follows:electrical, electromagnetic, magnetic,gravity, seismic reflection and refraction,borehole logging, ground penetratingradar. Each geophysical method is use-ful for measuring the vertical and/or lat-eral distribution of subsurface bodieshaving differing geophysical properties.

The success of any surface geo-physical survey is dependent upon manyfactors. One of most important is thecompetency of the person(s) responsiblefor carrying out the survey and interpretsthe data. An understanding of thetheory, field procedures and methods forinterpretation of data along with an un-derstanding of the site geology is neces-sary to successfully complete a geophysi-cal survey. Properly planned, con-ducted, interpreted and reported, a geo-physical survey can provide a wealth ofsubsurface information that could not beobtained otherwise.

The other most important issue isthe client-geophysicist relationship. Theclient should provide all the informationrelated to site conditions and geologicaldata prior to the geophysical survey.Both sides should identify the problemclearly, and know the expectations fromthe geophysical survey. The success of

the geophysical survey is strongly depen-dent upon the two-way communicationsof the client and the geophysicist.

This presentation is a review of thecapabilities and limitations of basic geo-physical methods currently being em-ployed in the engineering and environ-mental industries. In this presentation,several case studies from refineries, gasstations, old oil and gas platforms, andshopping centers will be included. Thepresentation will cover magnetic, grav-ity, conductivity, time-domain sounding,resistivity, borehole logging, and groundpenetrating radar, seismic reflectionmethods.

Abstract 1: Travel time computa-tion on the SEG/EAGE 3D saltmodel for prestack depth migrationby Mo Le Wei

In data processing prestack depthimaging, Kirchhoff integral migration isthe prevailing method. In this method,travel time computation which governsthe correct lateral/depth positioning andfocusing of reflection events, is the mostcritical component in determining thequality of the migration images.

The controlled data set, SEG/EAGE3D salt model, simulating environmentof the Gulf of Mexico has been widelyused by many people for research andhas been used in the industry to bench-mark data processing softwares. We usethis data set to elaborate our method oftravel time computation so as to improvethe quality of Kirchhoff migration im-ages. Practice shows that applicationof the travel time of the most energeticarrivals in Kirchhoff migration producesbetter focused and more continuousimages with higher signal to noise ratio.We will present analysis to design a fast,accurate and stable method of ray trac-ing to compute traveltime. We analyzethe energy decay mechanism of seismicwaves to design a ray selection criterionof minimum velocity contrast (MVC) toselect the most energetic arrival. A com-plete suite of data examples show thatour procedure successfully obtains ac-curate and stable travel time of the most

D o u g l a sGordon Lang ,74 of Bellaire,Texas diedpeacefully onthe 25th ofJuly at the M.D. AndersenH o s p i t a l ,Houston.

Mr. Lang, “Peter” to a multitudeof friends and colleagues, was bornand lived in the city of Leeds, En-gland. In 1941 at the age of 15 heenlisted in the in the British MerchantNavy as a Radio Cadet, rising toShips Radar Officer and seeing ser-vice world wide during and immedi-ately after World War II.

In 1949 he departed the servicesin search of a wider education at Cityof London Colleges while workingfor Decca Radar as an engineer/de-signer. During this time he compiled

the book “Marine Radar” which waspublished by Pitman and became a stan-dard Navy/ AirForce service manual.

His last company move was in 1956when he was recruited by Ray Geophysi-cal Co. as an instrument supervisor andspent the next ten years covering all fivecontinents and all known instrumenta-tion.

By 1965, he had become Managerof Technical Training and Houston washis de-facto home. He became anAmerican citizen and acquired a homewhich he immediately filled with the ar-tifacts of his primary hobby - antiquenavigation equipment - upon which hewas a recognized authority.

After the merger of Ray and Pettyto form Geosource in 1972 he servedthe new company in many operationaland corporate positions before return-ing to his preferred discipline as man-ager of all training for Geosource, a po-sition he held until his retirement from

Halliburton Exploration Division in1990.

During this time his perfection-ist imprint covered every manual,specification and curriculum put outby the company on any subject. Hisvideo based training course ontheoretical geophysics was interna-tionally renowned in the early eight-ies

energetic arrival at both the near-fieldand far-field from the source in this com-plex and yet realistic geological model.Data processing prestack depth migra-tions show that our procedure producesmore coherent sedimentary, salt top/base and subsalt images than the oldmethods.

Abstract 2: Fast and accurate fi-nite-difference solutions of the 3Deikonal equation parametrized incelerityby Antonio Pica.

One major problem with 3D PSDMprocessing resides in the travel time com-putation step. Not only this travel timehave to be accurate, but the speed ofcomputation has to be high otherwisein certain cases there is a bottleneck inthe overall processing turn around time.The algorithm proposed here for solv-ing the 3D eikonal equation overcomesthese two difficulties. A high speed of

computation is obtained by using acoarse sampling, but the accuracy of thesolutions is ensured by parameterizingthe differential equation, not in time, butin celerity, which designes the averagevelocity appearing in the Dix hyperbolicequation. The computations are madeon a Cartesian system of coordinates,but the wave-front curvatures are never-theless implicitly taken into account.Usually, eikonal solutions represent thefirst arrival travel times. In the schemepresented here, the upgoing head-wavesare naturally cancelled, as this methodproceeds by extrapolating the traveltimes downward. As an option for someparticular cases, the undesireddowngoing refracted waves can be can-celled by imposing some geometricalconstrains to the wave-front paths. Thebehavior of this kind of technique istested and analyzed with the 2DMarmousi dataset example.

OctoberSeismic Fundamentalsby Don MacphersonOctober 17-18, Dallas, TX

Application and Interpretation ofConverted Wavesby Rob Stewart & Jim Gaiser,October 23-24, Houston, TX

OctoberSeismic Fundamentalsby Don MacphersonOctober 17-18, Dallas, TX

This course is intended to be a thor-ough review of all the key geophysicalconcepts relevant to the interpretationof seismic data. It also contains a de-tailed description of technologies thathave recently become “hot topics” in ourindustry such as 4-D seismic data. Addi-tionally, the course attempts to providethe attendee with a clear understandingof technologies that have a significantimpact on the economics of a projectsuch as depth migration or AVO pro-cessing.

The course material is offered in avery graphic manner and therefore re-quires no prerequisite knowledge of con-cepts such as seismic migration. Al-though concepts such as seismic migra-tion are discussed in detail, the total fo-cus is on what the interpreter needs toknow about these processes. The coursecontains very little mathematics. Thereare however several key equations (forexample in the section on seismic ve-

locities) that are relevant to seismic in-terpretation and are included becauseseismic interpreters should be comfort-able with them.

Concepts such as wavelet tuning areillustrated with numerous PC programsthat are free to participants. Several ofthese are extremely useful to the seis-mic interpreter such as the program forhandling seismic velocities with the Dixequation.

Course Outline• The nature of seismic data, what’s

propagating• Seismic data acquisition, land and

marine data• Reflections at an interface, the reflec-

tion coefficient• Wavelets in the seismic data• Tuning and the thin bed response• Overview of seismic data processing• Seismic velocities, stacking velocities,

interval velocities, converting todepth

• Overpressure and its effect on stack-ing velocities

• The imaging process, why we DMOand migrate the data

• 3-D migration• Prestack migration in time and depth• 3-D data and the concept of bin gath-

ering• Direct hydrocarbon indicators and

AVO with a little rock physics• 4-D seismic data

Who Should AttendGeologists, Geophysicists, ReservoirEngineers, or anyone needing a thor-ough understanding of seismic data.

GEOPRESSURESA WORKSHOP

Date: October 12, 2000Time: 7:30 AM to 5:00 PM

Venue: Shell Auditorium, One Shell Plaza, 910 Louisiana, Houston.

This is an all-day workshop for geoscientists and engineers dealing with geopressures. It is an opportunity to understand and reviewsome of the fundamental aspects of geopressure phenomena at different scales and their possible solutions. The topics coveredinclude the following:

• Geopressures as drilling hazards as well as valuable clues for exploration.• Dominant causes• Special considerations for deepwater exploration.• Geophysical methods, rock physics, and underlying assumptions and models, which are used

analyze geopressures before, during, and after drilling, at basinal to prospect scales.• Case histories.

IAGC/IPAAS ConferenceThe International Association of Geophysical Contractors (IAGC) and Independent Petroleum Association of America

(IPAA) will hold the second in a series of day-long conferences on non-exclusive geophysical data at the HESS Building(5430 Westheimer) in Houston, Texas on Tuesday, October 31st.

The conference is especially appropriate and beneficial for independent oil company people - owners, explorationmanagers, geologists, geophysicists, landmen, attorneys and others - who wish to learn about how to gain the greatestbenefit from this low-cost but powerful oil and gas finding too.

The dramatic growth of the “spec” data business has greatly enhanced wildcat drilling success rates and allowed largenumbers of oil companies affordable access to 3-D seismic technology, which is changing dramatically due to sweepingchanges created by the internet.

More information on the conference, including registration material is available from IAGC at [email protected] or bycalling 713-957-8080. The registration deadline is October 10, 2000.
