This section deals with the current state-of-the-art in the underground gasification of coal and the underground retorting of oil shale. It gives a brief account of the chemical and pyrolytic reaction mechanisms of both processes and introduces a variety of in situ gasification and retorting methods that have been developed in the United States and many other countries.
