..., eight characteristic parameters reflecting petrology, reservoir structure, reservoir physical property, interlayer, fluid property and heterogeneity were selected from 18 typical low permeability carbonate reservoirs in the Middle East, and the data matrix was constructed. The covariance matrix...

... heterogeneity experiment Acetone shale sample Wettability is an important property of shales, yet its determination is quite challenging. There is no consensus as to the most appropriate method of assessing shale wettability. The air-liquid-rock and liquid-liquid-rock contact angles (Sessile/Captive...

.... However, the local deformation behavior reflects a strong heterogeneity at the scale of the minerals that are present. The nanoindentation and SEM-EDS images provide strong evidence that both cracking and plastic deformation always occur around indentation imprints even at high in-situ stress condition...

... compressible two-phase flow in coal, accounting for gas desorption, matrix shrinkage, heterogeneous permeability distribution, and cross-flow. Fractured porous medium is modelled by a dual-porosity radial model. Stress-dependent permeability and matrix shrinkage effects are modelled using the Palmer-Mansoori...
