As part of DOE's Underground Coal-Gasification program, activities at Sandia National Laboratories have been directed at Process and Technology Development. The project areas include (1) the development of a cornering water-jet drill for use in linking vertical wells in Underground Coal-Gasification (UCG) tests; (2) the development of a controlled-source audiofrequency magnetotelluric (CSAMT) surface geophysical technique for monitoring the process, and (3) the development of models for use in predicting the growth of the cavity. The accomplishments for the year include (1) the successful completion of the first phase of testing for the cornering water-jet drill, (2) the mapping of underground coal-mine fires and the Hanna II and Rawlins T-2 UCG test sites using the controlled-source audio-frequency magnetotelluric technique, and (3) the completion of a thermomechanical cavity-growth model.
