In Situ Retorting

In Situ Retorting. Method of retorting oil shale in situ. Crude shale oil can be obtained by either aboveground or in situ (in place) processing. True in situ (tis) retorting involves fracturing the shale in place, igniting the shale at the top of the formation, and feeding in air to sustain the combustion for pyrolysis. There are several variations to the in situ retorting approach. True in situ retorts and modified in situ retorts. In situ retorting offers the possibility of eliminating the problems associated with the disposal of large quantities of spent shale that occur with surface retorting. In the in situ retorting process, heat is supplied either by underground combustion or by introducing heated gases or liquids to the oil shale formation. The “true” in situ method consists of fracturing, retorting, and recovering the products through the use of boreholes from the surface. The icp utilizes electricity to heat the underground shale over a. An underground retort containing rubblized oil shale is subjected to retorting, thereby forming shale oil and off gases. Tests were run at temperatures from 20 to 500c and confining pressures to 1,500 psi with shale of 10 to 30 gal per ton.
