Three-way coupling of multiphase flow and poromechanics in porous media

We formulate a three-way coupling for both single phase flow and equation-of-state (EOS) compositional flow in a poroelastic medium. The algorithm is inspired by the previous work of Dean et al. [1]. An error indicator is calculated at each time step to determine if the mechanics equation must be solved and whether the fixed-stress iterative coupling is necessary; otherwise, only the flow equation is solved with an extrapolated mean stress. The...
