Mitchell Energy Corporation has implemented a LPG-dry gas miscible process in the Alvord (3000 ft Strawn) Unit in Wise County, Texas utilizing the DOE tertiary incentive program. The field had been waterflooded for 14 years and was producing near its economic limit at the time this project was started. This paper presents the results of the reservoir simulation study that was conducted to evaluate pattern configuration and operating alternatives so as to maximize LPG containment and oil recovery performance. Several recommendations resulting from this study were implemented for the project. Based on the model prediction, tertiary oil recovery is expected to be between 100,000 and 130,000 bbls, or about 7 percent of th oil originally in place in the Unit. An evaluation of the project performance to date is presented. In July of 1981 the injection of a 16% HPV slug of propane was completed. Natural gas is being used to drive the propane slug. A peak oil response of 222 BOPD was achieved in August of 1981 and production has since been declining. The observed performance of the flood indicates that the actual tertiary oil recovered will reach the predicted value, although the project life will be longer than expected. The results presented in this paper indicate that, without the DOE incentive program, the economics for this project would still be uncertain at this time.
