..., as a proxy for shale porosity, is well constrained, the pore pressure prediction may be in error because of the lithological variation in shale composition. Presence of solid organic matter in excess amounts in shale formations that have never been exposed to the pressure-temperature conditions in the oil...

... stress-density, and pore pressure-neutron porosity have been used to establish the overpressure mechanism. Wells are correlated on a regional scale to ascertain the variation of lithofacies corresponding to the onset of overpressure. Variation of geothermal gradients is also studied for Panna...

... by 5.6% compared to silica flour. The Young's modulus of granite waste was smaller than the Young's modulus of silica flour by 3%. Additionally, the porosity of granite waste was also smaller than the porosity of silica flour by 18%. 1. Introduction In the Petroleum industry, while drilling...

... of pressure drop, porosity and pore structure on fluid flow and heat transfer in porous media. The detailed distribution of velocity and temperature in complex pore space was obtained and presented visually. The results show that the increase of pressure drop will enhance the fluid transmission rate and heat...

..., well logs will provide that certainty. However, without the knowledge of rock strength, porosity, permeability, and Poisson's Ratio, the completion design may be lacking or underperforming. Although these reservoir properties can be fundamentally computed, porosity from sonic, density, or neutron logs...

... physics procedure to estimate porosity and absolute permeability and compare the pore-scale heterogeneities in different core samples. From the analyses that is evident that permeability can vary in even short distances of sampling in an unconventional play, such as the Bakken Fm. Therefore, assuming...

... and buildings. These rocks can be naturally or anthropically exposed to high temperatures. Consequently, relating their physical properties to temperature induced damage becomes extremely important. Key physical and mechanical properties, such as porosity, seismic wave velocities, electrical resistivity...

..., due to low porosity, low permeability, and well-developed natural fractures, tight sandstone reservoirs have strong stress-dependent damage caused by the decreases of formation pressure in the later stage of reservoir stimulation, which can reduce the reservoir permeability and then oil and gas...

The aim of this study is to investigate the effect of material elasticity, porosity, and tensile strength on the crack initiation stress level based on the results of over 3,000 experiments collected from the literature...

... nitrogen (LN2) into Eagle Ford core samples were conducted at the reservoir temperature (82 °C) and three treatment-pressures (1.38, 2.76, 4.14 MPa). Before and after each treatment-cycle, porosity, permeability, and ultrasonic velocities were measured. Porosity, permeability, and ultrasonic velocity...

Core A plugs are composed of calcite and show a wide range of pore types (e.g., vuggy, mouldic, micropores). Samples have been grouped as ‘micro-', ‘meso-', or ‘macroporous' based on pore type and size...
