Abstract
In this project we focused on Simulation of two-phase (gas-oil) flow in 2D anisotropic porous medium on unstructured grids by finite volume method.Since the permeability assumes to be full tensor, common discretization methods for pressure and flux equations couldn’t satisfy continuity conditions then a new method of discretization named continuous flux approximation introduced.In this new method, cell center pressure calculated by directly applying flux continuity conditions to control volume boundaries. In this project a ninepoint scheme is used, it means that for making the flux continuity conditions over each control volume in two dimensions all neighboring cells are involved.The reason...

Abstract
Reservoir simulation is a useful tool for efficient reservoir management and protective exploitation of non-renewable hydrocarbon resources as the main supplier of development programs in the country. Due to the nature of underground hydrocarbon reservoirs, the simulation faces several challenges, both in rock and fluid parts. These challenges should be overcome in order to provide reliable results from simulations. One of the major challenges pertaining to rock, is large discontinuous variations accompanied by anisotropy of rock permeability fields which causes numerous problems when governing equations are solved numerically. A viable numerical procedure shall account for complex reservoir...
