Devonian shale-specific computation methodology. Topical report, June 1988

Technical Report ·
OSTI ID:5622620
This report presents the application of the 'Devonian Shale-specific Formation Evaluation Model' for the evaluation of geophysical well logs in the Devonian shale. A procedure is outlined for determining lithology, porosity, and bulk volume free-hydrocarbon. The logging suite commonly utilized by ResTech for evaluation of the shales is presented. However, methods were developed for obtaining reliable results in certain areas with a reduced logging suite. The final report from an analysis includes a written document containing recommended completion intervals and perforations. Also included within the report are the results presented in both a log and listed format. The log format has an 11-inch and 22-inch presentation. In addition to lithology, porosity, and bulk-volume free-hydrocarbon that are presented on the 11-inch presentation, results from the borehole television, temperature survey, and mudlog are displayed on the 22-inch wide presentation.
