Title: Oil and Gas Development in the Denver-Julesburg Basin: ABSTRACT

Author(s): Harry L. Thomsen

Article Type: Meeting abstract

Abstract:

Close to 50 new producing areas have been discovered on the east flank of the Denver-Julesburg Basin since the discovery of oil in Cheyenne County, Nebraska, by the Ohio Oil Company in June, 1949. All of these fields produce from Dakota group sandstones of Cretaceous age, at depths ranging from 3,300 feet to 7,350 feet. Deeper objectives appear to be present but as yet are relatively untested in the central part of the basin.

Most of the new fields have been found by use of the seismic method. They appear to be located on structural anomalies of minor relief, but it is apparent from subsurface information that stratigraphic changes within the Dakota group often aid in controlling accumulation.

More than half of the undeveloped acreage in the basin is now under lease. Exploration and development work is proceeding at a high level particularly in the area outlined by recent discoveries, which covers over one-tenth of the total basin area.
