... is the product of the pore volume of the formation, total compressibility of the system, and maximum allowable pressure difference. Since the stress-strain relationship of a porous medium depends on the frequency and magnitude of the loading and unloading process, the total compressibility would be different...

..., reduction in pore volume is a rock deformation issue including the ever-changing pore compressibility. Typically, coupled geomechanics and flow simulation models do not account for such details; however, in this paper, we used in-house multi-phase dual-porosity model to show the effect and significance...
