... are used to simulate initial and long-term permeability accounting for reservoir depletion (i.e., increased net effective stress, matrix shrinkage). A previously validated case study is used to describe the post-embedment benefits of GPI based on the porosity model and history-matched reservoir properties...

... of fracture deformation comes from gas desorption-induced matrix shrinkage. Due to the matrix-fracture permeability difference, pressure changes faster in fractures. There is a matrix-fracture pressure equilibrium time lag. As matrix gas is released from matrices and enters fractures, matrix shrinkage may...

... 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...
