Modeling, Laboratory and Field Test Studies of Water Influx in the UCG Process. Final Technical Report

摘要

This report consists of two chapters: (1) water influx, and (2) cavity growth and subsidence. Chapter one discusses the importance of water influx in the underground coal gasification (UCG) process, modeling studies of water influx, and implications of these modeling studies. Chapter two covers cavity growth and subsidence; a model for the areal sweep, vertical cavity growth and implications of these studies. 11 refs., 16 figs., 3 tabs. (ERA citation 11:026834)
