The Goshen Hole Uplift: A Brief Review of its History and Exploration Potential

Abstract

The Goshen Hole uplift 1s a little recognized and sparsely explored feature in the northern end of the Denver Julesburg basin We believe there is excellent hydrocarbon potential on the uplift principally In Cretaceous (Hygiene, Niobrara, Wall Creek, Muddy, Dakota). Jurassic (Canyon Springs), Permian and Pennsylvanian objectives. There are diverse stratigraphic anomalres observed on seismic data in these horizons as well as numerous paleo structures. Basement tests are approximately in the 10.000 to 11,000 ft (3.048 - 3.353 m) range. The uplift has had recurrent movement since the Pennsylvanian; however a period of uplifting occurred in the Upper Cretaceous beginning by at least early Campanian time with intermit- tent uplift rn the Cenozoic. There are numerous subsurface shows and source beds in Paleozoic and Mesozoic horizons and oil seeps on the uplift which enhance the exploitations potential of this area
