Abstract: The two dimensional flow of oil through heterogeneous and bounded reservoirs, including gravity effects, is rigorously solved by finite differences .A family of finite differente scheures that depend on one parameter 0, which varies between 0 and 1, is applied.The system of linear equations is solved by a method based on Taylor Series of Matrix Functions (TSMF) .TSMF is compared with the traditional Alternate Direction Implicit (ADI) and Block Successive Over Relaxation (Block-SOR) methods .TSMF consumes less CPU time than ADI and Bloek-SOR, using appropriate values of 0 and time step At .The numerical simulator is then applied to study the drawdown response of a two layer reservoir with crossflow and gravity forces .The pressure response of crossfiow reservoirs lies between the response of the equivalent single layer system and that of the isolated layer system .When the vertical pressure gradient is increased by gravity, the gap between the response of the equivalent single layer system and that of the isolated layer system is enlarged .The pressure curves keep similar shapes as those of the nil gravity case .When the vertical pressure gradient is decreased by gravity, the gap is lessened .However, the pressure curves may become inverted .
