摘要:
A hydrocarbon containing formation may be treated using an in situ thermal process. A mixture of hydrocarbons, H2, 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. Heat may be supplied to the formation by reacting an oxidant with hydrocarbons adjacent to heater wellbores to generate heat. Generated heat may be transferred to the portion substantially by conduction to pyrolyze at least a portion of hydrocarbon material within the portion.

摘要:
An oil shale formation may be treated using an in situ thermal process. Heat may be applied to the formation to raise a temperature of a portion of the formation to a pyrolysis temperature. Heat input into the formation may be controlled to raise the temperature of portion at a selected rate during pyrolysis of hydrocarbons within the formation. A mixture of hydrocarbons, H2, and/or other formation fluids may be produced from the formation. The mixture may be separated into condensable hydrocarbons and non-condensable hydrocarbons. The condensable hydrocarbons removed from the formation may be a high quality oil that has a relatively low olefin content and a relatively high API gravity.

摘要:
An oil shale formation may be treated using an in situ thermal process. Hydrocarbons, H2, and/or other formation fluids may be produced from the formation. Heat may be applied to the formation from one or more heat sources to raise a temperature of a portion of the formation to a desired temperature. Some of the heat sources may be conductors placed within conduits. The conductors may be resistively heated so that the conductors radiantly heat the conduits. The generated heat may transfer to the formation.

摘要:
In an embodiment, a system may be used to heat a hydrocarbon containing formation. The system may include a heater placed in an opening in the formation. The system may allow heat to transfer from the heater to a part of the formation. The transferred heat may pyrolyze at least some hydrocarbons in the formation. The heater may be removable from the opening in the formation and redeployable in at least one alternative opening in the formation.
摘要:
A fitting for coupling ends of cores of three insulated conductors includes an end termination placed over end portions of the three insulated conductors. The end termination includes three separate openings that pass through the end termination longitudinally. Each of the insulated conductors passes through one of the openings with end portions of the insulated conductors protruding from one side of the end termination. Exposed cores of the end portions of the insulated conductors protrude from the end termination. A cylinder is coupled to the side of the end termination from which the end portions of the insulated conductors protrude. An electrical bus is coupled to the exposed portion of the cores. Electrically insulating material fills the cylinder such that the cores are substantially enclosed in the electrically insulating material. An end cap is coupled to the cylinder to seal off the interior of the cylinder.

A fitting for coupling an end of a first insulated conductor to an end of a second insulated conductor is described. The fitting includes a first splice housing placed over the end of the first insulated conductor and coupled to the first insulated conductor. The fitting also includes a second splice housing placed over the end of the second insulated conductor and coupled to the second insulated conductor. A sleeve is located over the end of the second insulated conductor and adjacent to the second splice housing. An interior volume of the fitting is substantially filled with electrically insulating material. The interior volume of the fitting is reduced such that the electrically insulating material substantially filling the interior volume is compacted.
