Mathematical simulation of gas and water coning in petroleum reservoirs by the dynamic material balance technique
… oil well is one of the most difficult numerical simulation problems. Because of the convergent flow patterns and small sizes of the inner grid blocks, the radial coordinate models used to study the problem have a tendency to become unstable. Since several hundred pore volumes may flow through the …
