A major objective of the nation's energy program is to develop processes for cleanly producing fuels from coal. One of the more promising of these is underground coal gasification (UCG). If successful, UCG would quadruple recoverable U.S. coal reserves. Under the sponsorship of the Department of Energy (DOE), Lawrence Livermore National Laboratory (LLNL) performed an early series of UCG field experiments from 1976 through 1979. The Hoe Creek series of tests were designed to develop the basic technology of UCG at low cost. The experiments were conducted in a 7.6-m thick subbituminous coal seam at a relatively shallow depth of 48 m at a site near Gillette, Wyoming. On the basis of the Hoe Creek results, more extensive field experiments were designed to establish the feasibility of UCG for commercial gas production under a variety of gasification conditions. Concepts and practices in UCG are described, and results of the field tests are summarized.
