Abstract
The present disclosure relates to a method to improve the performance of reservoir simulators, and to widen the range of systems that can efficiently be modeled. The present disclosure relates to determining fluid flow in a subsurface reservoir. One embodiment divides the reservoir into discrete volume elements. Fluid within the volume elements is represented, for example, by it pressure, saturation, and/or composition. For one or more fluid phases comprising the fluid, the potential for each volume element is determined. The volume elements are ordered according to their potentials for each phase comprising the fluid. A local, fully coupled time-step sequence is determined using a local conservation solution based on the potential ordering of and for each fluid phase. The fluid flow is determined using a global conservation solution based on the local, fully coupled time-step sequence.
