Hao Huang, R. Chick Wattenbarger, Xiuli Gai, William P. Brown, Owen J. Hehmeyer, Jianlin Wang and Ted A. Long Using a fully coupled flow and geomechanical simulator to model injection into heavy oil reservoirs International Journal for Numerical Methods in Fluids 71
This paper proposed a numerical formulation, which can fully couple multicomponent porous flow and nonlinear geomechanics. The simulation results revealed that geomechanical factors, such as in situ stress anisotropy or uneven deformation of reservoir rock and attached impermeable layer, can result in skewed plastic strain and, hence, alter the sweep of the injected fluid. The results also show that the coupled geomechanics simulation gives rather different transient pressure response from that of uncoupled simulation.
