In November 1980 a high resolution seismic survey was conducted at the Department of Energy, Laramie Energy Technology Center's underground coal gasification test site near Hanna, Wyoming. The objectives of the survey were to determine the feasibility of utilizing high resolution seismic technology to locate and characterize underground coal burn zones and to identify shallow geologic faults at the test site. Seismic data acquisition and processing parameters were specifically designed to emphasize reflections at the shallow, 61-91 meter depths of interest. A three-dimensional grid of data was obtained over the Hanna II, Phases 2 and 3 burn zone. Processing included time varying filters, deconvolution, trace composition, and two dimensional, areal stacking of the data in order to identify burn zone anomalies.
