Computer Simulation of Fracture in Small Scale Borehole Experiments in Oil Shale
The Energy Research and Development Administration (ERDA), with support from the Bureau of Mines and the U.S. Geological Survey, has begun to develop technologies that can make untapped fossil fuel reserves economically extractible. As part of this ERDA program, Sandia Laboratories, Albuquerque (SLA), the Los Alamos Scientific Laboratory (LASL), and the Laramie Energy Research Center, Laramie, Wyoming, have initiated in situ shale oil recovery programs. An important objective of these programs is to develop techniques for the in situ fracturing of oil shale to provide increased permeability and allow conversion of the shale kerogen to shale oil by appropriate thermal processing. This objective requires a quantitative understanding and description of the fracture and fragmentation of oil shale.
