Abstract:
East Nancy field, discovered in April 1968, produces from 2 zones. The upper Smackover reservoir is oolitic limestone. The lower reservoir is a sandstone generally called Norphlet by the industry, but included in the Smackover in this paper.
Accumulation is the result of closure on a low-relief salt anticline. The structure is "buried," exhibiting no reversal on beds above the Cotton Valley. Consequently, shallow subsurface and gravity interpretations offer little aid in delineating the anomaly. East Nancy was first drilled, and apparently condemned, by Southwest Gas Producing Company in 1959, following an extensive conventional seismic program. The discovery well was located on the basis of CDP data, which defined the structure.
