Control strategies for abandoned in-situ oil shale retorts

Technical Report ·
OSTI ID:6767423
;
Prevention of groundwater pollution resulting from in-situ oil shale development will require a novel control technology. Based upon information available regarding the problems and related technologies, certain candidate control technologies appear technically and economically feasible. These technologies and their projected costs are listed. Pending verification of certain assumptions, it appears possible to prevent pollution of groundwater for about $0.59 to $0.67 per barrel by recovering leachate and treating it on the surface; for about $0.74 to $2.85 per barrel by placing a grout curtain around an entire block of retorts; or for about $0.35 to $1.30 per barrel by backfilling abandoned retorts with a grout of surface-retorted spent shale. These cost projections are preliminary and subject to change as experimental data are generated and as design criteria are developed. The technical feasibility of these technologies has not been demonstrated, and many uncertainties remain concerning technologies as well as site-specific issues. Therefore, these cost projections are initial approximations which may not reflect actual costs at any specific site. Nevertheless, the projections are useful for RD and D decision-making. Detailed cost projections for each control technology are provided in this study.
