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.

What is claimed is: 1. A method for producing methane from a hydrocarbon formation, comprising: dewatering a first treatment area isolated by a plurality of freeze wells; dewatering a second treatment area isolated by a plurality of freeze wells, wherein a first impermeable hydrocarbon layer is between the second treatment area and the first treatment area, and wherein the first treatment area, the impermeable layer, and the second treatment area are at least partially horizontally displaced from each other; storing at least a portion of the water from the second treatment area in the first treatment area; and removing methane from the second treatment area. 2. The method of claim 1, wherein the first treatment area is subjected to an in situ conversion process prior to receiving water from the second treatment area. 3. The method of claim 1, wherein the second treatment area comprises a deep coal seam. 4. The method of claim 1, further comprising injecting carbon dioxide in the second treatment area to displace methane from the formation so that that the methane can be removed from the formation through production wells. 5. The method of claim 1, further comprising injecting carbon dioxide in the second treatment area to control pressure within the second treatment area. 6. The method of claim 1, further comprising injecting carbon dioxide in the second treatment area to maintain pressure in the second treatment area above a pressure outside of the second treatment area to inhibit ingress of fluids into the second treatment area. 7. The method of claim 1, further comprising sequestering carbon dioxide in the second treatment area. 8. The method of claim 1, wherein isolating the second treatment area with a plurality of freeze wells increases methane production by at least 40% relative to producing methane from the second treatment area without isolation. 9. The method of claim 1, wherein the first impermeable layer has a permeability of less than 0.1 millidarcy. 10. The method of claim 1, wherein at least two of the plurality of freeze wells isolating the second treatment area are arranged in a stacked pattern. 11. The method of claim 1, wherein at least two of the plurality of freeze wells isolating the second treatment area are arranged in a triangle pattern. 12. The method of claim 1, wherein at least a portion in the water in the first treatment area freezes to form a barrier. 13. The method of claim 1, further comprising allowing heat to transfer to at least a portion of the first treatment area from heaters located in the impermeable layer; and producing hydrocarbons from the first treatment area. 14. The method of claim 1, further comprising allowing heat to transfer to at least a portion of the second treatment area from heaters located in the second treatment area, the heaters being arranged in a staggered pattern. 15. The method of claim 1, further comprising allowing heat to transfer to at least a portion of the second treatment area from heaters located in the second treatment area, the heaters being arranged in a staggered X pattern. 16. The method of claim 1, further comprising dewatering a third treatment area isolated by a plurality of freeze wells, wherein a second impermeable layer is between the second treatment area and the third treatment area; storing at least a portion of the water from the third treatment area in the second treatment area; and removing methane from the third treatment area, and wherein the second treatment area, the second impermeable layer and the third treatment area are at least partially horizontally displaced from each other. 17. The method of claim 16, wherein at least two of the plurality of freeze wells isolating the third treatment area are arranged in a stacked pattern. 18. The method of claim 16, further comprising allowing heat to transfer to at least a portion of the third treatment area from heaters located in the third treatment area, the heaters being arranged in a W pattern.
