The objective of this investigation is to determine the physical and thermal properties of oil shale at elevated temperatures and to provide the required background information and analyses required for effective mine design and subsidence prediction for an in situ oil shale retorting operation. The reported tests were performed under varying conditions of temperature, confining pressures, and kerogen content. Tests were conducted on samples taken parallel and perpendicular to the bedding at a temperature range of 20 deg. to 500 deg. C, confining pressures up to 1,500 psi were applied, and kerogen content ranged from 10 to 30 gallons per ton. A review of current activity in the area of in situ retorting is included as an appendix and a comprehensive list of references for literature related to in situ retorting is provided.
