Abstract

The Mallet Unit, located in Cochran and Hockley Counties of west Texas, produces oil from the Permian San Andres dolomite as part of the larger Slaughter field. The Mallet Unit was evaluated for waterflood improvement and CO2 enhanced oil recovery. This paper discusses the modeling approach for optimizing the existing waterflood and designing a CO2-flood. Four components were found instrumental in achieving a reliable CO2-flood design. These four components are: (1) an Equation-of-State accurately matched with representative PVT data, (2) a reliable geological description validated by 23 years of waterflood history, (3) a compositional model which adequately describes the phase behavior and CO2 displacement mechanism, and (4) a valid scale-up technique for forecasting field-scale CO2-flood performance from pattern CO2-flood performance. With these four components, oil and CO2 production response forecasted from the compositional model and scale-up study were found to be in reasonable agreement with the field observation of a near by CO2-flood. This nearby CO2-flood has similar geology and fluids. Recommendations for waterflood improvement and CO2-flood design were made based on both black-oil and compositional simulation results.
