Title: Oil and Gas Possibilities in Central Nebraska Basin: ABSTRACT

Author(s): E. C. Reed

Article Type: Meeting abstract

Abstract:

The Central Nebraska basin comprises an area of more than 25,000 square miles bounded on the west by the Chadron-Cambridge arch, on the east by the Table Rock-Nehawka-Richfield arch, on the north by the Sioux uplift, and on the south by the Kansas-Nebraska line. For all practical purposes this basin is a northern extension of the Salina basin of Kansas. The area is extensively mantled with variable thicknesses of Cenozoic rocks resting on Cretaceous, Permian, and Pennsylvanian.

The Pennsylvanian rests on Precambrian at the margins of the basin but within the basin variable thicknesses of pre-Pennsylvanian sedimentary rocks are known to occur in thicknesses varying from small amounts up to more than 1,000 feet. Basement rocks are reached in the basin at depths of about 4,500 feet or less. The number of significant tests drilled in this basin to date is comparatively small and is certainly inadequate to disprove this large area. The only oil production in this basin to date is in the southwestern part where some Pennsylvanian production has been developed. Adequate reservoir rocks are known to be present in the pre-Pennsylvanian sediments in many parts of the basin. Ground-water mineralization in the pre-Pennsylvanian sedimentary rocks is generally low but thi condition is not believed to be completely unfavorable so far as the possibility of commercial accumulation of petroleum is concerned. The complex geologic history of the region presents some interesting possibilities for the accumulation of oil or gas in commercial amounts.
