Developing a Black Oil Simulator Using Unstructured Smart Gridding Technique

Study of two-phase flow in the reservoir has an important role in management and predicting the performance of oil and gas reservoirs. This includes solving the nonlinear equations, time-dependent hybrid equations in heterogeneous reservoirs. The most important issue in this regard is to generate the best mesh for the reservoir network leading to the best answer. In this technique, the variables of permeability distribution, well locus and streamlines are combined to generate the background grid. Using one of the techniques for mesh generation, the computational grid is generated. Two-phase flow modeling is developed on finite volume basis and the results are compared to the fine grid.
