The general goal of this research has been to develop basic data and mathematical models in order to better understand information obtained from large scale field experimentation in underground gasification of Texas lignite. The chemical engineering research has focused on the topics of combustion tube studies of water influx, investigation of cavity growth mechanisms, cracking of pyrolysis products, and analysis of flow patterns in UCG. The petroleum engineering research has focused on subsidence analysis, creep testing and modeling, and effects of overburden drying. Good agreement between subsidence model predictions and data from the Hoe Creek No. 2 field experiment has been obtained. Environmental effects of UCG have been studied both for surface processing of wastewater as well as subsurface phenomena. Activated sludge processing of wastewater seems feasible and pertinent laboratory data have been acquired. Adsorption characteristics and microbial activity for different species in contaminated groundwater have been determined for the Tennessee Colony, Texas, field test site. 100 references, 95 figures, 10 tables.
