"The purpose of this project is to demonstrate the technical feasibility of using superheated steam at l,OOO·F and 15OO psfg as a heat-carrying medium to retort the oil shale in situ and to provide a mechanism for the recovery of this oil with minimum impact on the environment. More specifically, the oil shale will be retorted by injecting superheated steam into the leached zone through an array of injection wells and recovering the steam/water/oil and gas produced from the leached zone through an array of production wells. The environmental research plan is designed to determine the surface and subsurface effects of project operations in order to allow estimates of the environmental impacts of commercial oil shale development."
