A subcrop map shows the Precambrian surface in SW. Nebraska. This shows the general structural configuration of the area with the updip limits of various rock units. A stratigraphic cross section is shown. All rocks from the Permian through the Reagan may be considered as objectives, although to date almost all the production in the area has come from the Basal Pennsylvanian sands. The trap at Sleepy Hollow field, which has produced over 23 million bbl from the basal sand and nearly 6 million from the Lansing, is created to the north by permeability pinchout in both reservoirs. Such stratigraphic closure is present in at least one direction in all basal sand fields, and with the possible exception of Reiher, also is present in the major Lansing accumulations. The basal sand fields have yielded over half of the area's cumulative production from reservoirs which will recover approx. 500 bbl per acre-ft. or 200,000 bbl from 10 ft of pay under 40 acres. Payout times vary as little as 1 mo. up to several years.
