Hydrogen production in underground coal gasification (UCG)
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2016ABSTRACTIn this article, the rationales of the hydrogen production in underground coal gasification are explained. The experimental conditions and process of the underground gasification in the Liuzhuang Mine, Tangshan, Hebei Province are introduced, and the experimental results are analyzed.

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.

CAVITY GROWTH MECHANISMS IN UCG WITH SIDE WALL BURN GASIFICATION
Proceedings of SPE Annual Fall Technical Conference and Exhibition, 1978Abstract A preliminary two-dimensional model for in-situ underground coal gasification is presented for discussion. The model describes cavity formation from the injection well end and link zone burn up, where the initial link zone geometry is assumed at this time. Cavity growth is predicted via an integral boundary

Lateral Drilling Technology Tested on UCG Project
IADC/SPE Drilling Conference, 1988Abstract This case history describes state-of-the-art lateral drilling technology used to complete an underground system of process wells for a UCG project In central Wyoming. The Gas Research Institute and the U.S. Department of Energy funded the project. Eastman Christensen's medium-radius system was selected to drill the wells.
