Minnelusa Sandstones of the Powder River Basin


The Minnelusa Formation study is designed to enhance both exploration and development efforts that are directed at Minnelusa reservoirs. GDI has created an extensive stratigraphic framework that documents the extent of these reservoir-potential intervals.

Minnelusa depositional models and lithofacies reservoir potential are determined through the integration of core, thinsection, and log analyses. Eight field studies are incorporated with a focus on reservoir characteristics, trap types, and deliverability.

The study components include an extensive summary text and figures, maps and cross sections, core and thinsection descriptions, and stratigraphic data appendices. These components provide the client with a presentation format that is concise and readily useable.

The study area covers over 5,100 square miles in Wyoming and Montana, within which 4,332 wells were correlated, and represents 12 man-years of geologic research.
