The McCamey field was discovered in September 1925 in Upton County, Texas. Burlington Resources Oil & Gas has recently unitized 8600 acres within the field for secondary recovery. The unit has produced an estimated 12% to 16% of the original oil-in-place, with no field-wide secondary recovery operations, indicating a large remianing target for waterflooding. The primary objective of the study is to quantify the waterflood potential in the McCamey Unit through volumetric calculations and analogy to waterflood projects in the area. A representative reservoir simulation model will serve to validate the study's major assumptions and provide direction for future data needs.

The results indicate waterflooding will be profitable at the McCamey Unit. All the major assumptions regarding initial and current fluid saturations, fluid contacts, and the geologic description appear to be reasonable. The major recommendation is to implement the waterflood project at the McCamey Unit. Additional data recommendations include fluid saturation, relative permeability, and reservoir fluid PVT data which will improve the understanding of the reservoir and improve the accuracy of the waterflood predictions.
