Mining And Conversion Of Oil Shale In A Gas Combustion Retort

Several systems have been proposed for the production of synthetic crude oil from oil shale. An economic analysis of one proposed system is presented in this paper. An oil shale complex to produce 100,000 barrels per calendar day of semirefined crude oil will require a capital investment of $426,216,400. This investment includes mining, retorting, intermediate pipelining, and partial refining. A selling price of $3.74 per barrel of product will be necessary to maintain a discounted cash-flow rate of 12 percent.
