Explosively produced fracture of oil shale. Progress report, July-September 1982
The Los Alamos National Laboratory is conducting rock fragmentation research in oil shale to develop the blasting and fluid-flow technologies required to prepare a rubble bed for a modified in situ retort. The first section of this report summarizes the rock fragmentation program completed with the cooperation of the Oil Shale Consortium and Science Applications, Inc.; it also details the plans for a joint DOE/Sandia National Laboratories/Los Alamos program based on the results of the Consortium program. In addition, Sec. I describes the explosive engineering tests conducted to evaluate dead-pressing characteristics and to verify the reversal-plane fracture capabilities of the ANFO slurry explosive used in the Consortium program. The second section presents a paper on computer modeling and theory that relates the permeability of fractured rock to percolation theory and statistical crack mechanics.
