As part of the Department of Energy's Underground Coal Gasification research program, activities at Sandia National Laboratories during FY84 have included cornering water jet drill development, subsidence and cavity growth modeling in support of the Tono PSC field experiments, field testing of the CSAMT remote monitoring technique, and laboratory experimentation and site characterization planning in support of the Eastern bituminous UCG program. Accomplishments for the year include completion of the cornering water jet drill program, including a field proof-of-concept demonstration; comparisons of cavity growth and subsidence model calculations with results of the Tono field experiments, demonstrating the ability of these models to predict cavity/overburden interactions affecting the gasification process; remote CSAMT monitoring of the Tono field experiment and demonstration of the ability of the technique to detect process effects remotely and in real time; development and testing of a laboratory gasification system to investigate early cavity growth and other phenomena in swelling Eastern bituminous coals; and detailed site characterization planning for the upcoming Eastern UCG field program. 40 references.
