Slattery field was discovered in 1963 on the eastern flank of the Powder River basin. The field has produced over 6.5 million bbl of oil in the past 22 years. Located 10 mi south-southeast of Gillette, Wyoming, T49N, R68, 69W, it is 2 mi long and 1.4 mi wide. Although there is minor Cretaceous Muddy production, the sandstones of the Minnelusa Formation are the principal reservoirs. Previous interpretations have suggested the continuous, widespread nature of the sandstone reservoirs; however, this study indicates the limited nature of each reservoir and its relative stratigraphic position. Sand dunes are present in the Upper Minnelusa at five separate zones that partially overlap southwest to northeast. Four of the zones form separate reservoirs as determined by geologic correlations, log analysis, reservoir information, and production data. The southern end of the Slattery field structure abuts a south-southwest-trending structural nose. An Opeche Shale-filled valley parallels the field on its eastern updip edge and truncates upper reservoirs, forming part of the trapping mechanism.
