The directional properties of Devonian Shale were determined through five physical property measurements: ultrasonic velocity measurement, point load test, Brazilian test, measurement of directional elastic constants and elastic property variation in the horizontal plane. The core, with a total length of 1300 feet (Depth 2720 to 4026 feet) was taken from Well number 20403 in Lincoln County, WV. The results show that: bedding planes are quite distinct, and the most preferred direction of fractures in the bedding plane is N60/sup 0/E.
