A process may include providing heat from one or more heaters to at least a portion of a subsurface formation. Heat may transfer from one or more heaters to a part of a formation. In some embodiments, heat from the one or more heat sources may pyrolyze at least some hydrocarbons in a part of a subsurface formation. Hydrocarbons and/or other products may be produced from a subsurface formation. Certain embodiments describe apparatus, methods, and/or processes used in treating a subsurface or hydrocarbon containing formation.

Certain embodiments provide a method for treating a subsurface formation. The method includes providing one or more explosives into portions of one or more wellbores selected for the explosion in the formation. The wellbores are formed in one or more zones in the formation. The explosives are controllably exploded in one or more of the wellbores such that at least some of the formation surrounding the selected wellbores has an increased permeability. One or more heaters are provided in the one or more wellbores.

A method of forming and maintaining a low temperature zone around at least a portion of a subsurface treatment area is described. The method includes reducing a temperature of heat transfer fluid with a refrigeration system. The heat transfer fluid is circulated through freeze well canisters and placed in a formation around at least a portion of the subsurface treatment area. An initial temperature of the heat transfer fluid supplied to a first freeze well canister is in a range from about −35 C. to about −55 C. At least one of the well canisters includes carbon steel. The heat transfer fluid is returned to the refrigeration system.

A system for heating a subsurface formation is described. The system includes a first elongated heater in a first opening in the formation. The first elongated heater includes an exposed metal section in a portion of the first opening. The portion is below a layer of the formation to be heated. The exposed metal section is exposed to the formation. A second elongated heater is in a second opening in the formation. The second opening connects to the first opening at or near the portion of the first opening below the layer to be heated. At least a portion of an exposed metal section of the second elongated heater is electrically coupled to at least a portion of the exposed metal section of the first elongated heater in the portion of the first opening below the layer to be heated.

A heating system for a subsurface formation includes an electrical conductor and an insulation layer at least partially surrounding the electrical conductor. A jacket that includes ferromagnetic material at least partially surrounds the insulation layer. The outside surface of the jacket is configured to be at little or no electric potential while the electrical conductor is conducting electricity and while the jacket is at temperatures below the Curie temperature of the ferromagnetic material.

A fitting for coupling ends of insulated conductors includes a sleeve to couple an end of a jacket of a first insulated conductor to an end of a jacket of a second insulated conductor. The sleeve is located between end portions of the insulated conductors. At least one of the ends of the sleeve is angled relative to the longitudinal axis of the sleeve. The sleeve has a longitudinal opening that extends along the length of the sleeve substantially the distance between end portions of the jackets of the insulated conductors. The longitudinal opening allows electrically insulating material to be filled into the sleeve.
