Abstract A new numerical model for low-permeability reservoirs is developed. The model incorporates the nonlinear characteristics of oil-water two-phase flows while taking into account the initiation pressure gradient. Related numerical solutions are obtained using a finite difference method. The correctness of the method is demonstrated using
a two-dimensional inhomogeneous low permeability example. Then, the differences in the cumulative oil and
water production are investigated for different starting water saturations. It is shown that when the initial water
saturation grows, the water content of the block continues to rise and the cumulative oil production gradually
decreases. More >
