Little Creek Waterflood Unit, Lincoln and Pike Counties, Mississippi
Since April 1962 Shell Oil Co. has operated a peripheral line drive waterflood of the 10,750-ft lower Tuscaloosa (Cretaceous) Denkman sand in the Little Creek Field of S.W. Mississippi. The accumulation is stratigraphically controlled and occurs in an extensive series of alluvial point bar deposits across a very gentle southerly dipping nose. The crude is a 39$ API gravity oil which was highly undersaturated at initial conditions. Early production behavior indicated depletion drive with slight water influx, and primary recovery was estimated to be 25 million bbls, or 24.5% of the oil originally in place. In the waterflood, as a result of a favorable mobility ratio and remarkably uniform rock properties the volumetric sweep efficiency has exceeded 90%. Despite the high connate water saturation, the displacement efficiency by water injection has been quite efficient. Based on observed field floodout performance the ultimate recovery is calculated to be 45 million bbls. (11 refs.)
