Reservoir rock properties pdf

This presentation gives a basic overview of the basis of reservoir rock properties. It contains a detailed analysis of reservoir rock properties. Reservoir Rock Properties.

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.

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. The principal reservoir rocks are sandstone and carbonate formations. Typically, the physical properties and the composition of the sandstone and carbonate reservoir rocks are varying Cecil The scale of investigation used in reservoir studies is microscopic geological thin section , macroscopic wireline log, core plug , megascopic reservoir mod- elling grid cell , and gigascopic well test. In this section, the focus will be on microscopic and megascopic scales to characterise the reservoir. By studying a core sample of any reservoir rock under telescopic equipments, to determine the reser- voir rock and the reservoir textures either solid or brittle. From the shape and size of the connected apertures in a reservoir, the estimation of the ability of the reservoir rock to store and transfer the fluids can be evaluated. Hence, the reservoir rock physical properties are very reliant on the composition and the rock texture. The following are the main important characteristics of oil reservoir properties that control the overall reservoir performance and production potential:.

Gain calibration must be refreshed from time to time to fit the probe response drift with aging.

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 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.

Electrical Conductivity of Fluid-Saturated Rocks Porous rocks comprise an aggregate of minerals, rock fragments, and void space. Thus, Ro. Next slide the pin to lock the lid until the ball thrust is engaged. Connect the air to the air inlet. The volume of crushed sample is then determined by either pycnometer or immersing in a suitable liquid. This effect will be compensated with a correction factor f. The samples also must have sufficient mechanical strength to withstand the stress imposed by centrifuging. Engineering Environmental Engineering Mechanical Engineering. Hence, the aim of this is to get familiar with of the main rock properties parameters, the way they can be measured and the sources of errors in the results obtained from the laboratory measurements. Align the first core with the groove each side of the belt. If this name does not exist yet, this file will be created as a copy of the master GammaLogger. Non-hydrocarbon gas injection followed by steam—gas co-injection for heavy oil recovery enhancement from fractured carbonate reservoirs. Cornell, D.

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.

Various materials including fritted glass, porcelain, and cellophane have been used successfully as diaphragms. Pressure Release o Before relieving the radial or the axial pressure, be sure to open the build-in valve of the manual pump. Saturation is defined as that fraction, or percent, of the pore volume occupied by a particular fluid oil, gas, or water. The book is enriched with numerous examples from a wide variety of applications, to help readers understand the topics. Academic Documents. The shape factor is a function of the core diameter and the size of the gasket opening. One draw back of this machine is its noise. The only dif- ference in the two systems is the manner of expressing the length over which the pressure drop occurs. The curve labeled Suite 1 No. Formations of varying lithology and, hence, grain density limit applicability of this method.
