2 PHASE RELATIVE PERMEABILITIES USING THE ULTRACENTRIFUGE

Two phase immiscible displacements in the ultracentrifuge were used fo r the determination of the relative permeability characteristics of a variety of systems including Berea sandstone. Baker dolomite and plugs from the Rainbow Keg River Reefs. The transient production data for e ach plug were collected and were used for the estimation of the relati ve permeabilities. A computer simulation algorithm was developed for t his purpose. The program uses explicit history matching of the product ion data by fitting them using Corey type exponents for the relative p ermeability. Both oil flood and water flood data were utilized. The pa per describes the experimental procedure, the development of the model and representative experimental results. In general, the proposed alg orithm better fits the tighter carbonate samples rather than the data from the more permeable samples. The simulation seems to be very sensi tive to the capillary pressure data.
