Armand A Gregoli: Method of in-situ hydrogenation of carbonaceous material. Cities Service Company, George L Rushton, William N Patrick, February 26, 1985: US04501445 (242 worldwide citation)

In-situ hydrogenation of an underground coal formation is carried out by fracturing the formation and sealing it, to provide an in-situ reactor site. Then a liquid solvent stream and a gaseous hydrogen stream are introduced into the fractured formation, allowing reaction and conversion of the coal t ...

Larry S Bouck: Electrode well completion. Cities Service Company, George L Rushton, November 15, 1983: US04415034 (127 worldwide citation)

The electrode of an electrode well is formed by inserting a heating device into the borehole and heating the surrounding formation to a temperature at which the hydrocarbon-containing material undergoes thermal cracking, resulting in a coke-like residue surrounding the heater. This conductive and pe ...
