The invention relates to a computer system for modeling an oilfield having a subterranean formation and an underground reservoir therein. The computer system includes a repository storing a geomechanical model for representing at least a portion of the subterranean formation and the reservoir, the geomechanical model comprising a stress equation and a fluid flow equation, a processor and memory storing instructions when executed by the processor comprising functionalities for combining the stress equation and the fluid flow equation into a matrix equation, and modeling the oilfield by solving the stress equation and the fluid flow equation simultaneously.

Fully coupled simulation for fluid flow and geomechanical properties in oilfield simulation operations

An efficient and cost-effective technique is provided to perform modeling of a reservoir in a subterranean structure. A compartment model of fluid compartments in a reservoir is generated, and based on the compartment model and a geomechanical model of the subterranean structure, movement of a ground surface due to volumetric change of the compartments is calculated. Satellite measurements of the ground surface are received over time, where the received satellite measurements of the ground surface over time indicate movement of the ground surface. The movement of the ground surface indicated by the received satellite measurements is compared with the calculated movement, and based on the comparing, one or more properties of the geomechanical model are adjusted.
