A method for installing a horizontal or inclined subsurface heater includes placing a heating section of a heater in a horizontal or inclined section of a wellbore with an installation tool. The tool is uncoupled from the heating section. A lead in section is mechanically and electrically coupled to the heating section of the heater. The lead-in section is located in an angled or vertical section of the wellbore.

A method for installing a horizontal or inclined subsurface heater, comprising: providing a heating section of a heater to a horizontal or inclined section of a wellbore with an installation tool;uncoupling the tool from the heating section; andmechanically and electrically coupling a lead-in sec
1. A method for installing a horizontal or inclined subsurface heater, comprising: providing a heating section of a heater to a horizontal or inclined section of a wellbore with an installation tool;uncoupling the tool from the heating section; andmechanically and electrically coupling a lead-in section of the heater to the heating section of the heater, wherein the lead-in section is located in an angled or a vertical section of the wellbore. 2. The method of claim 1, further comprising removing the tool from the wellbore after uncoupling the tool from the heating section. 3. The method of claim 1, wherein the lead-in section has an electrical resistance less than the heating section of the heater. 4. The method of claim 1, wherein the lead-in section is mechanically coupled to the heating section using a coupling joint. 5. The method of claim 1, wherein the heating section comprises a receptacle at one end for accepting and coupling to the lead-in section. 6. The method of claim 1, wherein the heating section is mechanically secured in the wellbore with the installation tool. 7. The method of claim 1, wherein the heating section is at least about 10 m in length. 8. The method of claim 1, wherein the lead-in section passes through an overburden of a subsurface formation. 9. The method of claim 1, wherein the heating section is placed in a hydrocarbon containing layer of a subsurface formation. 10. The method of claim 1, further comprising providing electrical power to the heater. 11. The method of claim 1, further comprising providing electrical power to the heater, and providing heat to at least a portion of a subsurface formation from the heater. 12. The method of claim 1, further comprising providing electrical power to the heater, and providing heat to at least a portion of a subsurface formation from the heater such that heat from the heater superpositions heat from another heater in the subsurface formation. 13. The method of claim 1, further comprising providing electrical power to the heater, providing heat to at least a portion of a hydrocarbon containing formation from the heater, and allowing heat to mobilize and/or pyrolyze at least some hydrocarbons in the formation. 14. The method of claim 1, further comprising providing electrical power to the heater, providing heat to at least a portion of a hydrocarbon containing formation from the heater, allowing heat to mobilize and/or pyrolyze at least some hydrocarbons in the formation, and producing at least some of the mobilized and/or pyrolyzed hydrocarbons from the formation. 15. A method for providing heat to a subsurface formation, comprising: installing a heater comprising a heating section and a lead-in section into a wellbore in the subsurface formation, wherein the installation comprises:placing the heating section of a heater in a horizontal or inclined section of the wellbore with an installation tool;uncoupling the tool from the heating section;mechanically and electrically coupling the lead-in section of the heater to the heating section of the heater, wherein the lead-in section is located in an angled or a vertical section of the wellbore;providing electrical power to the heater; andproviding heat to at least a portion of a subsurface formation from the heater. 16. The method of claim 15, wherein the lead-in section has an electrical resistance less than the heating section of the heater. 17. The method of claim 15, wherein the heating section is at least about 10 m in length. 18. The method of claim 15, wherein the lead-in section passes through an overburden of the subsurface formation. 19. The method of claim 15, wherein the heating section is placed in a hydrocarbon containing layer of the subsurface formation. 20. The method of claim 15, further comprising providing heat to at least a portion of the subsurface formation from the heater such that heat from the heater superpositions heat from another heater in the subsurface formation. 21. The method of claim 15, further comprising providing heat to at least a portion of a hydrocarbon containing layer in the subsurface formation from the heater, and allowing heat to mobilize and/or pyrolyze at least some hydrocarbons in the layer. 22. The method of claim 15, further comprising providing heat to at least a portion of a hydrocarbon containing layer in the subsurface formation from the heater, allowing heat to mobilize and/or pyrolyze at least some hydrocarbons in the layer, and producing at least some of the mobilized and/or pyrolyzed hydrocarbons from the layer.
