Abstract

A method for hydrocarbon management of a reservoir is provided. The method includes generating a model of a reservoir comprising a plurality of homogenized mixed finite elements in an unstructured computational mesh. The unstructured computational mesh may be coarsened to form a plurality of coarser computational meshes in the model. A convection-diffusion subsurface process may be evaluated on a coarsest computation mesh. A result may be transferred from the coarsest computational mesh to a finest computational mesh, and a performance parameter for the hydrocarbon reservoir may be predicted from the model. The predicted performance parameter may be used for hydrocarbon management of the reservoir.
