Pressure Relaxation in a Hole Surrounded by a Porous and Permeable Rock

Combustion, Explosion and Shock Waves, 2002
The problem of explosion in a hole surrounded by a porous medium is considered. Integral equations describing pressure relaxation in the hole due to gas filtration into the surrounding porous space are obtained within the framework of plane one-dimensional, radial, and spherical formulations.

A new fracture permeability model: Influence of surrounding rocks and matrix pressure

Journal of Petroleum Science and Engineering, 2020
Abstract An appropriate fracture permeability model needs to include terms that characterize the effects of surrounding rocks and varying matrix pore pressure. This paper describes the use of Eshelby's inhomogeneity theory to derive equations that can be used to predict fracture permeability behavior for different shapes of reservoirs whose elastic ...
