Ultrasonic Velocity and Elastic Constants of Antrim Oil Shale

摘要

Ultrasonic velocities have been measured in 30 core samples from well 201. Both longitudinal and shear wave velocities were measured across core diameters at thirty degree intervals around the circumference in 22 of the samples. No significant angular variation of ultrasonic velocity was found in any of these. Plots of the average velocities between 1166 feet and 1486 feet are presented. In the Antrim, which lies between 1179 feet and 1422 km/s and the average shear wave velocity is 2.60 km/s. Actual velocities in the Antrim vary by + - 6% from these averages. Just above and below the Antrim the measured velocities are somewhat greater than the average Antrim values. Mass densities have also been determined for these samples and combined with the velocity data to obtain elastic constants. (ERA citation 05:023643)
