2020-8-31 An Interval velocity profile is usually used to predict pore pressure especially where existing calibration well data are scarce (Fig. 1) . However, using seismic velocity to predict pore pressure in a proposed well location is not the only decisive answer. The velocity changes in the shale (i.e., low-permeability beds) are result of compaction disequilibrium and additional
The geological reserves obtained with the commonly used flowing material balance (FMB) method are significantly impacted by the accuracy of the pore compressibility. Therefore, a new form of the FMB method is proposed in this study which can determine the pore compressibility and geological

For hydrocarbon explorationists, porosity (especially effective porosity) and permeability are probably the most important properties of any rock. Pores, therefore, are discussed throughout this book, and this relatively short chapter will serve mainly to give examples of the range of pore
Other articles where Pore is discussed: coal: Porosity: part by the presence of pores that persist throughout coalification. Measurement of pore sizes and pore distribution is difficult; however, there appear to be three size ranges of pores: (1) macropores (diameter greater than 50 nanometres), (2) mesopores (diameter 2 to 50 nanometres), and (3) micropores (diameter less than 2

Geological factors that control the deposition of turbidite systems, sequence stratigraphy, major faults, unconformities, and salt also affect pore pressure. In complexly faulted structures, formation pressures may be compartmentalized and may vary between different sands.
Keywords: pore geometry, pore structure, sandstone, Kozeny’s equation, J-Function, microscopic geological features 1. Introduction The main issues in rock typing of a sandstone is to link the geological processes forming the sandstone pore architecture - pore geometry and pore structure - with petrophysical properties.
