LABORATORY STUDIES OF COAL DRYING, PYROLYSIS, AND COMBUSITON FOR UCG
Proceedings of SPE Annual Fall Technical Conference and Exhibition, 1978Abstract Experimental and theoretical analyses show that uncontrolled water invasion during underground coal conversion (UCC) is harmful at all stages of UCC. By contrast, if water invasion is prevented, coal porosity can be created for further processing, pyrolysis can yield uniform hydrocarbon products ...

Reservoir-Geomechanics of Underground Coal Gasification (UCG)
2016The Underground Coal Gasification (UCG) is still not in a worldwide operation despite inheriting an old idea which is nearly one and a half century old. Aside from effects by other fuel sources on development of the UCG and from a technical perspective, this delay is due to the complex nature of the process.
