A hydrocarbon containing formation may be treated using an in situ thermal process. Hydrocarbons, H, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. The portion may be allowed or forced to cool after mixture production is ended. Carbon dioxide may be stored within the portion.

In situ thermal processing of a hydrocarbon containing formation with carbon dioxide sequestration

A coal formation may be treated using an in situ thermal process. Hydrocarbons, H , and/or other formation fluids may be produced from the formation. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. The portion may be allowed or forced to cool after mixture production is ended. Carbon dioxide may be stored within the portion.

A method for heat injection into a subterranean diatomite formation is provided. The method utilizes a heater that is placed directly in the diatomite formation without cement around the heater. Diatomite is very soft, and will quickly fill in around the heater, operation of the heater will sinter the diatomite and significantly increase the original thermal conductivity and strength of the diatomite.

Heat injection process

A method for heat injection into a subterranean diatomite formation is provided. A heater is placed in a wellbore within the diatomite formation, and the heater is then operated at a temperature above that which the heater could be operated at long term in order to better sinter the formation in the vicinity of the wellbore. The improved sintering of the diatomite significantly improves the heat transfer coefficient of the diatomite and thereby increases the rate at which heat can be injected from a constant limited long term heater temperature.
