Harold J Vinegar, Eric P DeRouffignac, Carlos A Glandt, Thomas Mikus, Mark A Beckemeier: Oil recovery process. Shell Oil Company, Del S Christensen, March 29, 1994: US05297626 (288 worldwide citation)

A process to recover oil is provided wherein an oil containing subterranean formation is heated by conductive heat transfer from heat injectors operating at temperatures above 900.degree. C. The high temperature levels of this process result in high recoveries of initial oil in place, and recovery o ...

A method for heat injection into a subterranean formation is provided. The method utilizes flameless combustion and a gas fired heater having an electrical heated surface for ignition of the gas. The absence of a flame eliminates the flame as a radiant heat source and results in a more even temperat ...

Carlos A Glandt, Harold J Vinegar, Michael Prats: Method of producing tar sand deposits containing conductive layers. Shell Oil Company, May 22, 1990: US04926941 (265 worldwide citation)

A method is disclosed for producing thick tar sand deposits by preheating of thin, relatively conductive layers which are a small fraction of the total thickness of a tar sand deposit. The thin conductive layers serve to confine the heating within the tar sands to a thin zone adjacent to the conduct ...

Carlos A Glandt, Harold J Vinegar, John W Gardner: Method and apparatus for producing tar sand deposits containing conductive layers having little or no vertical communication. Shell Oil Company, October 29, 1991: US05060726 (253 worldwide citation)

An apparatus and method are disclosed for producing thick tar sand deposits by preheating of thin, relatively highly conductive layers which are a small fraction of the total thickness of a tar sand deposit, with horizontal electrodes and steam stimulation. The preheating is continued until the visc ...

Peter Van Meurs, Carlos A Glandt: Thermal drainage process for recovering hot water-swollen oil from a thick tar sand. Shell Oil Company, May 26, 1987: US04667739 (6 worldwide citation)

Hot liquid-containing water-swollen tar is produced from a tar sand by injecting steam into a well, which is at least initially open and substantially free of obstruction to vertical fluid flow throughout a long vertical interval from the bottom of the tar sand, by producing said liquid from the bot ...
