Title: Analysis of the Devonian shales in the Appalachian Basin. Volume II. Appendices

Technical Report ·
OSTI ID:6464960

Thirty-three wells were core drilled from 1975 through 1981 for the Eastern Gas Shales Project in the Appalachian Basin. The following appendices are a compilation by well of all the fracture data, mechanical characterization tests, stratigraphic projections, geologic structural interpretations, and gas production information available through the Unconventional Gas Resources Library at DOE/METC, Morgantown, West Virginia. The well summary charts that are located as the last figure for each well description contain the detailed fracture distributions and mechanical test results for the stratigraphic members cored. The gamme ray log and density log are reproduced on each chart to show the correlation to stratigraphic members of the Devonian Shale sequence. A large quantity of data was collected in the early stages of the program to define the relationship of radioactivity to the individual shale members. The relationship serves as a useful tool in correlating the radioactive organic shales across the entire Appalachian Basin. Temperature and noise logs were included, when they were available, to show zones of gas emanation in the well bore. The mechanical test results columns include pretest fractures in the samples, maximum ultrasonic velocity directions, orientation of cracks from point load tests, weakest tensile strength directions from directional tests, and crack orientations from hydrofracture tests when available. All of this information has also been plotted by stratigraphic member and summarized at the bottom of each column for comparison with the other physical properties of the shales.
