A method of heating a portion of a subsurface formation includes drawing fuel on a fuel carrier through an opening formed in the formation. Oxidant is supplied to the fuel at one or more locations in the opening. The fuel is combusted with the oxidant to provide heat to the formation.
1. A method of heating a portion of a subsurface formation, comprising: positioning one or more fuel carriers on a conveyor;drawing fuel on at least one of the fuel carriers on the conveyor through an opening formed in the formation;supplying oxidant to the fuel at one or more locations in the openi
1. A method of heating a portion of a subsurface formation, comprising: positioning one or more fuel carriers on a conveyor;drawing fuel on at least one of the fuel carriers on the conveyor through an opening formed in the formation;supplying oxidant to the fuel at one or more locations in the opening; andcombusting the fuel with the oxidant to provide heat to the formation. 2. The method of claim 1, further comprising initiating combustion of the fuel at one or more locations in the opening using one or more igniters. 3. The method of claim 1, wherein the fuel comprises coal, oil shale, or biomass. 4. The method of claim 1, further comprising treating gas exiting the opening. 5. The method of claim 1, further comprising drawing a clean-up bin through the opening to remove ash from the opening. 6. The method of claim 1, wherein initiating combustion of the fuel occurs at or near a transition from an overburden to a portion of the formation that is to be heated. 7. The method of claim 1, wherein supplying oxidant comprises passing oxidant into openings in one or more conduits positioned in the opening. 8. The method of claim 1, further comprising controlling the oxidant supplied to the fuel to control the heating of the formation. 9. The method of claim 1, wherein the opening is one of a plurality of openings in the formation, and wherein the fuel carrier is configured to pass in a loop through two or more of the openings in the formation. 10. The method of claim 1, wherein the opening is a u-shaped opening, mine shaft, or tunnel. 11. The method of claim 1, wherein the heating provides sufficient heat to mobilize at least some hydrocarbons in the formation. 12. The method of claim 11, further comprising producing at least some mobilized hydrocarbons from the formation. 13. The method of claim 1, wherein the fuel carrier is one of a plurality of fuel carriers, and further comprising supplying fuel to the fuel carriers from one or more supply stations, and adjusting the amount of fuel supplied to one or more of the fuel carriers to control the heating of the formation. 14. A system for heating a portion of a subsurface formation, comprising: an opening formed in the formation;a conveyor positioned in the opening;fuel carriers coupled to the conveyor, wherein the conveyor is configured to draw at least one fuel carrier through the opening, and wherein at least one fuel carrier is configured to hold fuel to be combusted in the opening; andone or more oxidant conduits positioned in the opening configured to supply oxidant to at least one fuel carrier at one or more locations in the opening. 15. The system of claim 14, further comprising one or more clean-up bins coupled to the conveyor, at least one clean-up bin being configured to remove ash from the opening. 16. The system of claim 14, further comprising one or more igniters configured to initiate combustion of the fuel. 17. The system of claim 14, further comprising one or more supply stations configured to supply fuel to the fuel carriers. 18. The system of claim 14, further comprising one or more exhaust treatment systems configured to treat gases exiting the opening. 19. The system of claim 14, wherein the conveyor is configured to pass through two or more openings in the formation in a loop. 20. The system of claim 14, wherein the opening is a u-shaped wellbore, mine shaft, or tunnel.
