The Water-Alternating-Steam-Process (WASP) has been utilized on Section 13D, West Coalinga Field since 1988. Originally implemented to control premature, high-temperature steam breakthrough, the process has improved sales oil recovery in both breakthrough and non-breakthrough patterns. A desktop, semi-conceptual simulation study was initiated in June 1993 to provide a theoretical basis for optimizing and monitoring the WASP project. The simulation study results showed that the existing WASP injection strategy could be further optimized. It also showed that conversion to continuous hot waterflood was the optimum injection strategy for the steamflood sands. The Section 13D WASP project was gradually converted to hot waterflood during 1994. Conversion to hot waterflood has significantly improved project cash flow and increased the value of the Section 13D thermal project.
