Mathematical simulation of gas and water coning in petroleum reservoirs by the dynamic material balance technique

<p>"The prediction of coning behavior at a producing 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 inner grid blocks during a rather small time interval, instabilities are likely to occur in the saturation calculations for these grid blocks. The dynamic approach to saturation calculations is a method which first computes the correct material balance and then calculates the saturation necessary to maintain this balance under the current flowing conditions. This work presents the results obtained from a coning model which used this technique. These results indicate that the model exhibits stable saturation calculations both during cone formation and after breakthrough"--Abstract, page ii.</p>
