Shell Oil Company, May 9, 2006: US07040400 (262 worldwide citation)

A method for treating a relatively low permeability formation containing heavy hydrocarbons in situ may include providing heat from one or more heat sources to a portion of the formation. The heat may be allowed to transfer from the heat sources to a selected section of the formation. The transferre ...
