PRU Fee, an idle lease in the Midway Sunset Field has been a site of a U.S. DOE-sponsored Class III project. A geologic and stratigraphic model of the site was constructed using logs and core data. Geostatistical approach was used in generating reservoir images. Reservoir simulations were performed to study the effectiveness of various processes and to examine the sensitivity of parameters. The study showed that oil can be recovered economically from the lease using conventional steam flood technology provided the injectors are completed an optimum distance above the oil water contact. Simulations also showed that it was possible to recover additional oil by appropriately placing horizontal producers later in the life of the flood.
