The U.S. Department of Energy in Morgantown, West Virginia, and the U.S. Geological Survey and Petroleum Information Corp. in Denver, Colorado, have created two large data files for the Eastern Gas Shales Project (EGSP). All computer-compatible well, outcrop, and sample data generated by EGSP contractors from Devonian shales throughout the Appalachian basin are being edited, converted to a data base, and accessed by Department of Energy contractors to produce digital printouts, charts, and maps.

The EGSP Well Data File was developed as an extension of the Petroleum Information Well History Control System (WHCS) and contains geologic, engineering, and production test data for more than 6,000 wells. The EGSP Sample Data File contains geochemical, lithologic, and physical characterization data on more than 50,000 samples from 17 EGSP cored wells, and 140 additional wells and outcrops.

Well and sample data can be retrieved to produce (1) production test summaries by formation and location; (2) contoured isopach, structure, and trend surface maps of Devonian shale units; (3) sample summary reports by location, well, contractor, and sample number; (4) cross sections displaying digitized log traces and geochemical and lithologic data by depth for wells; and (5) frequency distributions and bivariate plots.

EGSP Data System products are being used by EGSP contractors to help solve Devonian shale exploration and research problems in the Appalachian basin. Although part of the EGSP Well Date File is proprietary, and distribution of complete well histories is prohibited by contract, maps and aggregated well data listings can be made available to the public through published reports.
