The controlled source audio-frequency magnetotelluric (CSAMT) technique will be used to monitor an underground-coal-gasification (UCG) experiment. The UCG experiment will be conducted in late summer of 1983 at the Washington Irrigation and Development Co. (WIDCO) property near Centralia, WA. Previous field experiments, mapping the Hanna II, Phases 2 and 3 and the Rawlins T-2 UCG cavities, indicate that the CSAMT technique is capable of mapping an active UCG process. It is expected that a CSAMT monitoring system will give one-meter resolution of the width of the process. The data-acquisition system (hardware and software), measurement philosophy, model calculations of expected results, pre-test CSAMT data, and overall system design are discussed. 10 figures, 1 table.
