Title: Raven Creek Field, Campbell County, Wyoming: ABSTRACT

Author(s): Charles E. Tranter

Article Type: Meeting abstract


Raven Creek field is located on the eastern side of the Powder River basin of Wyoming. Discovered in March, 1960, the field presently consists of 38 producing wells and 11 dry holes. Production is from the "B" sand unit of the upper member of the Minnelusa formation of Permo-Pennsylvanian age. Depth of production is about 8,300 feet. The trap is formed by updip truncation of the "B" sand unit against Opeche shale at the post-Minnelusa unconformity. Erosion of the productive sandstone appears to have been controlled by a resistant dolomite which overlies the "B" sand unit and by structural configuration present at the close of Minnelusa deposition. The trap is on the western flank of a pre-Opeche anticline, the axis of which has been breached by post-Minnelusa erosion. Bas nward tilting has destroyed the anticlinal closure which probably existed and strengthened the stratigraphic closure along the western flank.
