In general, naturally occurring rocks are saturated with fluids, water, oil, or gas Amyx et al. Any formation rock can produce oil, gas, and water which are considered as reservoir rock. A reservoir rock is a rock has an adequate perme- ability and porosity to permit fluids flow, to accumulate and to extract in viable volumes Daniel and Lapedes Normally, hydrocarbons exist in sandstones, carbonate, and shales formations and also are present in metamorphic and igneous rocks basement rock.

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. An original porosity is developed during the deposition of the material, and later compaction and cementation reduce it to the primary porosity. Secondary porosity is that developed by some geologic process subsequent to deposition of the rock. Primary porosity is typified by the intergranular porosity of sandstones and the inter- crystalline and oolitic porosity of some limestones. Secondary porosity is typified by fracture development as found in some shales and limestones and the vugs or solution cavities commonly found in limestones. Rocks having primary porosity are more uniform in their Thts author also Wrote the orlglnal chapter on this topic m the edition with coauthor James W. Amyx deceased] D. For direct quantitative measurement of porosity, reliance must be placed on formation samples obtained by coring. Unit cells of two systematic packings of uniform spheres are shown in Fig. The porosity for cubical packing the least compact arrangement is

Pressure applied to the assembly is increased by small increments.

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.

The set mode on oil pump is delta pressure and the test begins by setting a small delta pressure. If no bubble comes after the first minute elapsed, stop the process and fix the leak. The details of modifying this equa- tion are omitted because they are essentially the same as the ones used in the horizontal rectilinear flow systems. Start circulating cold water in the condenser. Also, corrections may be applied for the change in permeability because of the reduction in confining pressure on the sample. This can be done through the panel available in the software. It consists of one or more subsurface lithological units of either sedimentary or carbonate origin. Set the flexible tubing into the calibration brine contained in a beaker.

Select the "Info" sheet. Adjust them if necessary. Oil peak. Porosity measurement on core plugs: The porosity of reservoir rock may be determined by using core analysis, well logging technique or well testing. It is an important control on the amount of recovery. Several methods of determining effective porosity are compared in Table World Oil March and April The energy level X value is displayed and the total counts Y value is refreshed continuously. Air commonly is used as the fluid in permeability measurements. A permeameter designed for the determination of the permeability of rocks with either gas or liquid is il- lustrated in Fig. Figure below shows the core slabbing machine Fig. The solvents selected must not react with the minerals in the core. These variations were considered to be due to slippage, a phenomenon well known with respect to gas flow in capillary tubes. Reservoir rock.
