Method for controlling instability of liquid saturation computations.
Soc Petrol Eng J 1970 Mar; 10(1):5-7
A method is described for controlling instability in finite difference computations of liquid saturation near the bore hole of a recovery well. Differences of pressure- and saturation-dependent variables are indexed offcenter, upstream and downstream alternately, to provide a stabilizing average. Employing this algorithm, it was found that size of the time step could be increased by a factor of 4 without loss of numerical stability.
