Abstract: A fine computer model covering an area includes a fine grid. A fault follows a fine-grid-path. The fault divides the area into a first fine side and a second fine. A model of a source of fluid flow is on the first fine side of the area. A model of a sink of fluid flow is on the second fine side of the area. The computer coarsens the model. The fault follows a coarse-grid-path in the coarsened model. The coarse-grid-path divides the area into a first coarse side and a second coarse side. The model of the source and the model of the sink are on the first coarse side of the area. One of the source or the sink is moved to the second coarse side of the area.

Abstract: A hydrocarbon shale reservoir simulation system and method represented by a model having at least four different types of porosity nodes is described. The method includes the computer-implemented steps of characterizing porosity nodes within the model as one of natural fracture pore systems, matrix pore systems, induced fracture pore systems or vug pore systems. Following characterization, transfer terms between nodes are identified. Transfer terms may include transfer terms between vug nodes, matrix nodes, natural fracture nodes and induced fracture nodes. Once transfer terms have been assigned, the linear system for the model can be solved utilizing a linear solver. The method further includes the steps of utilizing the characterized pore nodes to define one or more subgrids that represent a zone within the reservoir, wherein the zone includes at least one node of each porosity type; and wherein the linear solver is applied by subgrid or associated sub-grids.
