Upper Cretaceous strata in the Powder River Basin—Formation tops database, structure and thickness contour maps, and associated well data
Upper Cretaceous strata in the Powder River Basin of northeastern Wyoming and southeastern Montana contain some of Wyoming’s most prolific oil and gas reservoirs as well as significant petroleum-generating source rocks. Using geophysical well logs from more than 2,200 oil and gas wells, key horizons within the Upper Cretaceous strata were identified throughout the basin, with the primary goal of a publicly available dataset containing depth-to-formation and assorted well data, including location, depth, datum, well type, and well class, for the Lower Cretaceous Muddy Sandstone through the Upper ...
