Abstract
A method for modeling a reservoir response in a subsurface system is provided. The subsurface system has at least one subsurface feature. Preferably, the subsurface system comprises a hydrocarbon reservoir. The method includes defining physical boundaries for the subsurface system, and locating the at least one subsurface feature within the physical boundaries. The method also includes creating a finite element mesh within the physical boundaries. The finite element mesh may have elements that cross the at least one subsurface feature such that the subsurface feature intersects elements in the mesh. A computer-based numerical simulation is then performed wherein the effects of the subsurface feature are recognized in the response. The reservoir response may be, for example, pore pressure or displacement at a given location within the physical boundaries.
