The gas potential of the New Albany Shale in the Illinois Basin is profiled on this CD-ROM. Featured on the disc are updated maps of the New Albany Shale (Devonian and Mississippian) in Geographic Information System (GIS) shapefile format, as well as 1991-1997 digital data for cores, an updated bibliography, and a database of more than 5,000 New Albany wells. Data fields in the well database include well permit number (identification number), UTM X, UTM Y, latitude, longitude, New Albany Shale top (elevation) in feet, thickness in feet, source of the data, data type, and pick type. Map plates include elevation of the top; thickness; average initial potential for the gas fields; mean random vitrinite reflectance; and locations of cores of the New Albany Shale. Stratigraphic cross-sections illustrating the distribution of the New Albany Shale members in the three-state area are included. Database tables are in dBase III format, which can be viewed by, and imported into, many spreadsheet and database programs. The ArcExplorer software program is included on the CD-ROM for viewing the GIS files. The map files can also be used with other standard industry mapping software.
