Typical Core Analysis of Different Formations

Chapter 27 Typical Core Analysis of Different Formations R.E. Jenkins. cw Lahoracorie\ ~nc.’

Introduction The early-day analysis of cores was largely an art, a qualitative matter of odors and tastes, sucking on the rock, and visual examination. The science of core analysis has evolved from such early beginnings, using developments in instrumental methods of chemical and physical analy- ses as they became available. Electron microscopy, mass spectrometry, gas chromatography, high-frequency phase analysis, acoustic wave train analysis, and nuclear mag- netic relaxation analysis are among the tools being used in the more sophisticated core testing today.

Many other techniques are available now to assist the geologist and petroleum engineer in the completion of wells and the evaluation and operation of oil and gas reservoirs, but core analysis still remains the basic tool for obtaining reliable information on the rock material pen- etrated. Study of representative core samples of an oil- or gas-bearing formation provides the only means for direct measurement of many important properties of the formation.

The minimum basic measurements made on cores generally comprise determination of porosity at no confining pressure, permeability at low confining pressure, and residual fluid saturations. Various supplementary rou- tine tests such as chloride, oil gravity, directional permeability, grain density, and grain size frequently are made as an aid in interpretation and evaluation. These data are the subject of this chapter.

Porosity Porosity is a measure of the void space or storage capac- ity of a reservoir material. Normally it is expressed as a percentage of bulk volume (%BV). Porosity may be determined by measurement of any two of the three quantities-grain volume, void volume, and bulk volume. Various generally acceptable methods and techniques for determining porosity are used by different laboratories. The void volume may be determined on a previously cleaned and dried sample by extraction or gas or air con-

tent, by saturation with a liquid, or by calculation from Boyle’s law upon compression or expansion of gas in the pore spaces of the sample. The other widely used method involves the separate determination of the gas, oil, and water contents of the sample, and the summation of these three values to obtain PV.

Most of the porosity data reported in the tables here were determined by the summation-of-fluids method. Comparison of porosity values obtained on samples from several thousand feet of core where measurements were made by both the summation-of-j&ids method and by a Boyle’s law method showed agreements, in general, of 0.1 to 0.5% porosity. Extensive checks of porosity values by resaturation with brine have shown values slightly lower than by the other procedures, indicating approximately 98 to 99% resaturation.

Permeability The permeability of a formation sample is a measure of its ability to transmit fluid. The permeability determination involves measurement of the rate of flow of a fluid of known viscosity through a shaped sample under a measured pressure differential. Air is the fluid normally used because of its convenience, availability, and relative in- ertness toward the core material. For many years, air- permeability measurements were corrected to an “equivalent” liquid permeability by use of the well-known Klinkenberg corrections. The permeability values reported in Tables 27.1 through 27.11 have been corrected to the “equivalent” liquid-permeability values, except as not- ed in the next paragraph.

In the whole-core orfill-diameter core analysis procedures, permeability is frequently measured in two horizon- tal directions. One measurement is made in the direction of the major fracture planes and is reported as k. This value indicates the effectiveness of the fractures as flow channels. The core sample is then rotated 90” and the second measurement is made in a direction of flow perpen- dicular to the direction of the first measurement. This

second value is normally reported as kw , and it is usually representative of the matrix permeability. Values for kw are reported in the following tables for formations that are normally subjected to the whole-core or full-diameter core analysis procedures. These values are not corrected to “equivalent” liquid-permeability values.

Liquid Saturations In the coring process, the core is exposed to the drilling fluid at a pressure greater than formation pressure. If the core contains oil or gas, some portion of this is flushed out and replaced by the drilling-fluid filtrate. As the core is brought to the surface and the external pressure is re- duced, the expansion of free gas or dissolved gas expels both oil and water from the core. As a result, the pore spaces of the cores recovered at the surface contain free gas, water, and oil if oil is present in situ. The oil and water contents normally are called “residual liquids.”

The residual oil and water contents of core samples normally are determined by retorting, vacuum distillation, or solvent extraction and distillation. The oil and water contents are converted to oil and water saturations as per- centages of PV. The oil and water saturation values reported in these tables represent data obtained by the retorting or the vacuum distillation procedures.

The water content of the core as recovered is generally called ’ ‘tofal wafer, ’ ’ and it may include some drilling- fluid filtrate or invasion water. The water saturation ac- tually existing at a given interval in a reservoir may be spoken of as the connate water or interstitial water. This interstitial-water saturation value, as reported in the ta-

bles, was determined in some cases by an empirical cor- relation factor applied to the total water value and in some cases by the use of capillary-pressure data for the specific reservoirs.

The API oil gravity values reported normally were measured on the oil recovered in the retorting or vacuum- distillation procedures. Comparison of gravity values obtained in oil recovered from cores with values obtained on produced or drillstem test (DST) oil indicates general agreement to within f2” API.

The liquid saturation data presented in the tables are from formations interpreted to be hydrocarbon-productive to some degree. In some cases, it was feasible to make a distinction between gas-, condensate-, and oil-productive zone characteristics. Table 27.9 shows core analysis data for zones identified as “transition” zones. These represent intervals or zones where an appreciable water cut is encountered during the life of a field. Such transition zones are present in many other areas and fields, but the available data did not permit a similar breakdown. It should be pointed out that the relative average depths reported for the gas-condensate, oil, and transition zones do not contradict the basic premises that gas overlies oil and that oil overlies water. The condensate-producing zones in the major formations in the U.S. gulf coast area, as presented in Tables 27.6 and 27.7, frequently are found at greater depths than are the oil-producing zones of the same formations. In a similar manner, the gas, oil, and transition zones shown in Table 27.9 for the extensive geologic groups and formations in the Oklahoma-Kansas area are found at different subsurface depths in different parts of the area.


Percussion Sidewall Core Data Percussion sidewall sampling is used extensively in the U.S. gulf coast area, and in other areas where productive intervals are encountered in relatively soft formations and where this type of coring has been found satisfacto- ry. The limited size of the individual samples has made it necessary to develop special procedures for handling

limitation of sampling 1 I the walls of the wellbore frequently result in questions of the degree to which sidewall core analysis data compare with data obtained on conventional wireline or diamond cores. Ta- ble 27.8 summarizes a study of core analysis results from more than 5,300 samples where approximately half were obtained by percussion-type sidewall sampling and the other half were obtained by conventional coring procedures.

Data From U.S. Areas Data from areas in the U.S. including Alaska, are presented in Tables 27.1 through 27.12. The formation and zone

names were selected in an effort to represent generally recognized nomenclature over large areas rather than local terminology. Some important producing formations are not included because of the lack of sufficient data at this time or because of their proprietary nature.

Data From Non-U.S. Areas The data from non-U.S. areas generally are lacking in pore liquid saturation values because of the formaTion evaluation practices in general use. The small quantity of data reported is a result of the problems of data being released. Data from Australia are presented in Table 27.13. Most of the Canadian data (Table 27.14) were provided by the Energy Resources Conservation Board of Alberta. The Middle East data are presented in Table 27.15. The North Sea data (Table 27.16) were published in the European Continental Shelf Guide. ’ Venezuela data presented in Table 27.17 were provided by Petrole- um de Venezuela S.A.
