The Integrated Reservoir Solutions Division of Core Laboratories is offering to interested companies the results of a geological and engineering evaluation of the Upper Devonian Duperow and Birdbear (Nisku) formations of eastern Montana and western North Dakota.
This report contains a database generated from more than 2500 wells, including description of cored intervals from 105 wells and outcrop sections. Wireline logs were acquired and used for control points in the basin with supplemental logs and production data being obtained from public domain sources.Three case histories comprise the engineering portion of this project. Each well represents major producing reservoir lithotypes of the Williston basin. The engineering parameters evaluated include:
