The major effort this quarter has been postexperiment analysis of Hoe Creek No. 3 and planning for future gasification experiments. Hoe Creek No. 3: Thermal data have been analyzed to determine the performance of the drilled horizontal channel during forward gasification. Thermal and material balance data are combined to determine late-time burn boundaries for the experiment. Surface subsidence after the experiment was completed is described. Process wells were inspected to determine failure characteristics and pinpoint late-time injection location. Ground-water quality before and after Hoe Creek No. 3 and the effects of aquifer interconnection on hydraulic measurements at the Hoe Creek No. 2 and No. 3 sites are discussed. Future experiments: Potential UCG sites are being characterized for future tests. Two sites in the Powder River Basin near Gillette, Wyoming are discussed. Preliminary plans for a deep site gasification experiment and a new method for in situ gasification of thick seams are presented.
