GEOLOGY AND GEOPHYSICS OF BADGER BASIN ANTICLINE, BIGHORN BASIN, WYOMING, USA
Badger Basin anticline in the Bighorn Basin, Wyoming, is a small-to medium-sized oil and gas field with nearly eighty years of hydrocarbon production from the fractured Frontier Formation. A three-dimensional3-Dseismic survey was acquired in the Badger Basin area, and processed prior to this study. Integration of surface mapping of exposed units and structure with subsurface well and 3-D seismic control provided an interpretation of the overall structure of Badger Basin anticline. A major basement-involved thrust fault controls the structure, dying out upsection and forming Badger Basin anticline. A secondary, subsidiary thrust fault is present on the gentle flank, locally modifying the overall Badger Basin anticlinal structure. Numerous normal faults trend perpendicular to the northwest-southeast fold trend, recording extension in the upper arc of the anticline. Some of these normal faults may compartmentalize the reservoir at the Frontier level. The overall structure probably formed during the maximum Laramide pulse of northeast-southwest compression. This study combines surface mapping with well log data and 3-D seismic data to characterize the overall Badger Basin structure.
