Numerical Simulation of Dual-Porosity Multiphase Flow Using Poroelasticity Theory

Abstract: Changes in reservoir pore pressure and temperature during injection or production affect rock deformation, which, in turn, causes alteration of porosity and permeability. Specifically, an increase in pore pressure (or a decrease in rock temperature) can create significant rock deformation and increase of the shear stress that could lead to rock fracturing and microseismic activity in the reservoir. Furthermore, porosity and permeability of rocks decrease because of the pore pressure decrease during depletion. … Show more

“…Additionally, specific storage of rocks is defined as an undrained poroelastic modulus by some researchers (e.g., Green & Wang, ) and is effective pressure dependent. Neglecting the pressure dependence of permeability and specific storage can introduce significant errors in flow simulations (Eker et al, ; Franquet et al, ; McKernan et al, ).…”
