Berchenko Ilya Emil, Fowler Thomas David, de Rouffignac Eric Pierre, Vinegar Harold J, Wellington Scott Lee, Zhang Etuan, Ryan Robert Charles, Shahin Gordon Thomas, Stegemeier George Leo, Karanikas John M: In-situ pyrolytic recovery from a hydrocarbon formation. Shell Int Research, February 18, 2004: GB2391891-A (4 worldwide citation)

A method of treating hydrocarbons in a formation (200) involves providing heat from one or more heat sources (202) to a portion of the formation (200) and allowing heat to transfer to a selected section of the formation (200) by conduction. The heat causes pyrolysis of the hydrocarbons and the produ ...
