Book excerpt: In situ oil shale retorting may result in a number of environmental impacts including degradation of local surface and groundwaters, low resource recovery, and subsidence. The target of present oil shale commercialization activities is the Mahogany zone in Colorado's Piceance Creek Basin. The principal oil shale resource in this area is surrounded by two confined aquifers. During mining and retorting, these aquifers are dewatered. When the site is abandoned, groundwater will reinvade the area and flow through the abandoned retorts, leaching potentially toxic or carcinogenic materials from the spent oil shale. This material may then be transported in local aquifers, withdrawn in wells or discharged into the Colorado River system as base flow. Certain control technologies appear potentially able to protect groundwater quality at reasonable cost. These include designing retort blocks to include a hydraulic bypass around abandoned retorts (about $0.50/bbl), placing absorbent clays in abandoned retorts to catch and hold leachable matter (about $0.50/bbl), collecting leachate and treating it on the surface (about $1.20/bbl), protecting abandoned retorts from leaching by placing a grout curtain around a block of abandoned retorts (about $2.00 to $3.00/bbl), or grouting abandoned retorts with spent shale (about $3 to $4/bbl).

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive study of in situ retorting at the Logan Wash has indicated the importance of developing baseline information including raw shale characterization, the elucidation of mineralogical and chemical controls on trace element mobilities from shales subjected to in situ processing, and the research necessary to identify strategies for control of recognized environmental impacts. It is impossible to assess the magnitude of trace element releases to be expected from a commercial in situ facility once banks of retorts or the entire facility is abandoned and dewatering of the area is concluded. However, laboratory-scale studies can indeed identify the relative environmental acceptability of spent shale materials generated by in situ processing. In this research, an attempt was made to relate mineralogy and leaching behavior of field-generated materials with leachate composition and solution chemical processes. The interaction of these factors will ultimately affect the impact of in situ processing on surface and groundwater quality.

Book excerpt: This paper has identified key issues in retort abandonment and has addressed research needs. Retort abandonment for vertical modified in-situ (VMIS) shale oil recovery is an environmentally sensitive research area that has received recognition only within the past five years. Thus, experimental data and information are, in general, limited. In addition, there is presently a wide spectrum of unresolved issues that range from basic problem definition to technical details of potential control technologies. This situation is compounded by the scale of the problem and the absence of a commercial industry. The problems involve large numbers and will require engineering on a gigantic scale. Abandoned retorts are large - up to 700 feet deep and several hundred feet in cross section. They will exist in huge blocks, several square miles in area, which are inaccessible at several thousand feet below the surface. The processes that will ultimately be used to extract the oil are undefined. The technology is in transition, and representative samples of materials have not been available for research. Research efforts in this area have concentrated on basic studies on the nature and magnitude of environmental problems resulting from VMIS oil extraction. These investigations have used laboratory reactors to generate spent shales and modeling studies to predict water quality and hydrologic impacts. The technology for retort abandonment is just now being developed, using engineering analyses to identify promising environmental control options and laboratory and modeling studies to determine feasibility. We expect that, as the environmental problems are better defined and understood, conventional control technologies will prove to be adaptable to a majority of the problems associated with this new process and that laboratory and modeling research on the problem definition will be refocused on technology development and field experiments.
