NTIS: PB/83-216374 :190 pages
The modified in situ process is one of the methods being considered for extracting oil from oil shale. One of the questions to be answered for this approach is the environmental consequence of underground retort abandonment. This report outlines a study that addresses the question in terms of a grouting solution. The report covers the development of a spent shale-ash-based grout that will fulfill the environmental requirements in terms of strength, stability, and impermeability. In addition, the grout will allow the reinjection of up to 50 percent of material mined and surface retorted as part of the process.
