Abstract:
1. A system for approximating a flow equation of a conventional reservoir simulator, the system being computer implemented and comprising a non-transitory computer readable medium containing: a program code means; and means for performing a method, wherein the method is a loose coupling method between a stress analysis system and the conventional reservoir simulator, the method being computer implemented and comprising adjusting the flow equation of the conventional reservoir simulator through: (i) removing a rock compressibility effect (c (ii) adding a volumetric deformation effect of rock and pores (α∂ε wherein the said adjustment of the flow equation of the conventional reservoir simulator, so that this is similar to a flow equation of a full coupling system, is conducted through the addition or removal of flow rate using wells, according to equations i) or ii): wherein: c Φ p is the pore pressure, t is time, α ε V B T is transmissibility and, said method providing a solution from a loose iterative coupling system until obtaining a convergence.
