application of m^3gm in a petroleum reservoir simulation

Reservoir formations exhibit a wide range of heterogeneity from micro to macro scales. a simulation that involves all of these data is highly time consuming or almost impossible; hence, a new method is needed to meet the computational cost. moreover, the deformations of the reservoir are important not only to protect the uppermost equipment but also to simulate fluid pattern and petroleum production strategy. in this regard, multiscale multiphysic mixed geomechanical model (m^3gm) is recently developed. however, applications of petroleum reservoirs through gas or water injection in the depleted reservoir are in concern. in the present paper, a multiscale finite volume framework and a finite element method are employed to simulate fluid flow and rock deformation respectively. the interactions of solid and fluid phases are instated through the m^3gm framework. then, its application in the petroleum reservoir through injection process is validated. the numerical results are compared with the fine scale simulations and reasonable agreement with high computational efficiency is obtained.
