Abstract
This work presents a new general type of primary production simulator using the unsteady state line source and sink solutions to the diffusivity equation and flow along pathlines to simulate multiphase flow below the bubble point. The results of model application to a circular reservoir were compared to the results of application of the Black Oil Applied Simulation Tool, BOAST, for the same case with favorable results. A number of runs were made for different cases on both circular and irregular shaped reservoirs. The mathematical basis for the model is outlined as is the computational technique and instructions for applying the model to .a reservoir of any shape, any size and containing any number of wells.
