Properties of Reservoir Rocks Daniel M. Bass Jr. These properties constitute a set of fundamental parameters by which the rock may be described quantitatively. Typical core-analysis data are presented to illustrate the description of porous media by these fundamental properties. Porosity Porosity is defined as the ratio of the void space in a rock to the bulk volume BV of that rock, multiplied by to express in percent. Porosity may be classified accord- ing to the mode of origin as primary and secondary.

To obtain realistic values of fluid saturation, it is necessary to choose the proper drilling fluid or to use in- direct methods of saturation determination.

This book explains the basic technologies, concepts, approaches, and terms used in relation to reservoir rocks. Accessible to engineers in varying roles, it provides the tools necessary for building reservoir characterization and simulation models that improve resource definition and recovery, even in complex depositional environments.

The most prominent features of reservoir rock are porosity, permeability, and fluid saturations. These properties related to the pore media system and its fluid distribution and flow forms. By carrying out laboratory analyses, using core samples, reservoir rock properties can be investigated. This is a preview of subscription content, log in via an institution.

The principal goal of reservoir characterization is to construct three-dimensional images of petrophysical properties. The purpose of this chapter is to review basic definitions and laboratory measurements of the petrophysical properties porosity, permeability, relative permeability, capillarity, and saturation. Pore-size distribution is presented as the common link between these properties. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves. This is a preview of subscription content, log in via an institution. Unable to display preview.

Stratigraphic reservoir characterization for petroleum geologists, geophysicists, and engineers. The fluid displaced by a sample may be observed either volumetrically or gravimetrically. To convert to 9-m from O-cm, divide the resistivity in Q-cm by All these devices are mounted on a frame rack Fig. The data reported by Newman were for samples that were not stress cycled. The reduction of pressure permits the expansion of the entrapped water, ail, and gas. The disadvantage here is that it is not suitable for poorly consolidated samples or chalky limestones. Porosity is a measure of storage capacity of a reservoir. Dead volume measurements for gas-liquid experiments are similar except that gas is injected instead of brine. You can adjust the time interval to your needs. Search inside document. S Waves Calculating the time of flight of S waves is far more difficult than the one of P waves. Jagar A. The basic rock particle-size distribution of the framework fraction, the material is usually finely crystalline and is called the matrix. The wettability of the rock is determined by indirect contact angle measurement using Rise in Core technique.

Two methods are used to evaluate the permeability of cores. Oil and gas are nonconductors. Well logging. A reservoir rock may contain liquid, gas, or both, and the vertical occurrence of. It is highly recommended that before any process the air probably contained within the core holder and the pumps are removed. What is Scribd? Close the confining valve HV This load the cylinder with the test liquid. Rock Compressibility. Belt travel is synchronized with the gamma-ray data by the software. To get an accurate measurement of those correction factors it is possible to measure the time of flight of the waves in a calibration plug. The principle of the method is that the size of the drop falling from a capillary tube depends on the surface tension of the liquid Fig.
