摘要

METHODS FOR MODELING FLOW FROM A FLOW INSIDE A RESERVOIR, TO PREDICT FLOW IN A RESERVOIR, TO PREDICTION OF ONE OR MORE PROPERTIES BASED ON FLOW OF A RESERVOIR, AND TO PREDICT PREDESSION GRADE IN A RESERVOIR COMPUTER READY. Methods and systems for reducing or eliminating numerical oscillations in solutions that occur when using conventional MPFA when modeling flow in a reservoir are provided. The technique can be called enriched multipoint flow approximation (EMPFA) and can be used to improve consistency and accuracy in constructing pressure interpolations in cells for the purpose of determining flow equations used to predict flow in a reservoir.
