Title: Green River Formation water flood demonstration project. Report for the period October 1992--March 1994

Abstract

The current project targeted three fluvial deltaic reservoirs in the Uinta Basin, Utah. In primary recovery, the performance of the Monument Butte unit was typical of an undersaturated reservoir whose initial pressure was close to the bubble point pressure. The unit was producing at a rate of 40 stb/day when the water flood was initiated. The unit has been producing at more than 300 stb/day for the past four years. The reservoir characteristics of Monument Butte were established in the geologic characterization study. The reservoir fluid properties were measured in the engineering study. Results of a comprehensive reservoir simulation study using these characteristics provided excellent match with the field production data. Extended predictions using the model showed that it would be possible to recover a total of 20--25% of the oil in place. In the Travis unit, logs from the newly drilled 14a-28 showed extensively fractured zones. A new reservoir was discovered and developed on the basis of the information provided by the formation micro imaging logs. This reservoir also behaved in a manner similar to undersaturated reservoirs with initial reservoir pressures close to the reservoir fluid bubble point. The water flood activity was enhanced in the Travis unit. Evenmore » through the reservoir continued to be gradually pressurized, the water flood in the Travis unit appeared to be significantly affected by existing or created fractures. A dual-porosity, dual permeability reservoir model provided a good match with the primary production history. The well drilled in the Boundary unit did not intersect any producible zones, once again illustrating the unique challenges to developing fluvial deltaic reservoirs.« less
