Unstructured and Structured Grids for Reservoir Simulation

Abstract

The new generation of flow simulators will be able to use unstructured grids as a support for discretizing the flow equation and representing properties. The Flex simulator developed at Stanford by the Supri-B consortium is a research platform for experimenting different numeral schemes and discrete elements. This article presents several research projects consisting of coupling Flex with GOCAD P-Grids, in the frame of a collaboration between the GOCAD and Supri-B consortia. The modular gridding approach proposed by S. Verma et. al. enables to take into account a gridding style varying over the reservoir. We have implemented an interactive meshing tool based on this approach and on the Delaunay triangulation proposed by J. Conraud. In addition to the initial modular gridding approach, our tool can take into account various constraints, such as internal boundaries, or a userdefined density map defined over the domain. These constraints have been also studied for structured grids, and an extension of the parameterization method implemented in GOCAD is currently studied, to construct grids optimized for flow simulation.
