Coal Density

Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being …

The Stress‐Memory Effect of Fracture Stiffness During ...

2021-9-30 · The roughness exponent was determined using the power spectral density approach as explained in Section 2.3.3. Assuming that the tensile fracturing in sandstones was exclusively intergranular, the higher frequencies reflect the surface roughness of the grains (Boffa et al., 1998). Those frequencies led to deviations in the power spectrum.
