A B S T R A C T CONDUCTIVELY HEATING A SUBTERRANEAN OIL SHALE TO CREATE PERMEABILITY AND SUBSEQUENTLY PRODUCE OIL Shale oil is subsequently produced from a subterraneaninterval of oil shale, where the interval is initiallysubstantially impermeable and contains a specified grade andthickness of oil s ...
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 ...
A method of treating a formation (200) involves heating (202) the formation (200) and allowing heat to transfer to a section (208) of the formation (200) so that the heat pyrolyzes at least 20 % of the hydrocarbons in said section (208) and that a mixture is produced which includes a condensable com ...
A process to recover hydrocarbons is provided wherein a hydrocarbon-containing subterranean formation (1) is heated by conductive heat transfer from a heat injector well (3) operating at temperatures above 900 �C. The high temperature levels of this process result in high recoveries of initial hydro ...
The invention relates to a method used for treating a hydrocarbon containing formation before producing hydrocarbon from the formation by using an in-situ heat treatment method, comprising: providing a first fluid comprising hot water or steam to part of the formation, wherein the first fluid firstl ...
A system is provided for injecting an injection fluid into an earth formation via a wellbore formed in the earth formation and for producing hydrocarbon fluid from the earth formation via the wellbore. The system comprises an injection conduit extending into the wellbore and being in fluid communica ...
A method is provided to remove contaminants from contaminated soil (102). The method may include withdrawing vapors from a vapor extraction well (202), estimating the amount of water vapor removed from the contaminated soil (102) in the vapors being withdrawn from the vapor extraction well, and appl ...
In an embodiment, a method for heating a hydrocarbon containing formation may include providing heat from one or more heaters to an opening in the formation. A first end of the opening may contact the earth's surface at a first location and a second end of the opening may contact the earth's surface ...
A process for producing hydrocarbons through a heater wellbore positioned in a hydrocarbon containing formation. The in situ treatment process may include providing heat from one or more heaters to at least a portion of the formation. The heat may be allowed to transfer from one or more heaters to a ...
