Charles H Ware, Leslie C Rose, Joseph C Allen: Recovery of oil by in situ hydrogenation. World Energy Systems, Arthur F Zobal, July 1, 1986: US04597441 (278 worldwide citation)

In a method of recovering petroleum from underground formations penetrated by a production well, superheated steam and then hot hydrogen are injected by way of the well into a preheated formation zone next to the well. The hydrogen is injected under sufficient pressure to cause hydrogenation of the ...
