Systems and methods for treating a subsurface formation are described herein. Some embodiments generally relate to systems, methods, and/or processes for treating fluid produced from the subsurface formation. Some methods include providing heat to a first section of the hydrocarbon containing formation from a plurality of heaters located in the formation; allowing the heat to transfer from the heaters to heat a portion of the first section to mobilize formation fluid; and producing formation fluid from the formation.
1. A method of treating a hydrocarbon containing formation, comprising: forming at least one wellbore in a hydrocarbon containing formation, the wellbore comprising at least two substantially horizontal or inclined portions, a first opening at a first position of the earth's surface and a second ope

The method of claim 1, wherein a second wellbore is positioned below the substantially horizontal or inclined wellbore in the hydrocarbon containing formation, wherein the second wellbore comprises a substantially horizontal incline portion. 5. The method of claim 1, wherein placing at least one of the heaters in at least a portion of the slot comprises removing a slot drill from the wellbore; coupling a portion of at least one heater to a pipe of the slot drill; and threading the heater through the slot. 6. The method of claim 1, further comprising removing at least one of the heaters from at least one slot; extending the slot into another portion of the hydrocarbon containing layer; providing an additional heater to a portion of the extended slot; providing heat to the additional portion of the hydrocarbon containing formation from the additional heater, wherein the additional heaters comprises an insulated electrical conductor; allowing the heat to transfer from the heater to the additional portion of the hydrocarbon containing formation; and producing additional hydrocarbons from the hydrocarbon containing formation. 7. The method of claim 1, wherein the hydrocarbon containing formation has low permeability. 8. The method of claim 1, wherein the hydrocarbon containing formation comprises oil shale and/or coal. 9. The method of claim 1, wherein forming the slot comprises using at least one of the heaters as an abrasive tool member of a slot drill. 10. A method of treating a hydrocarbon containing formation, comprising: allowing the heat to transfer from a plurality of heaters to a first section of the formation;producing hydrocarbons from the hydrocarbon containing formation;forming one or more slots in a portion of the hydrocarbon containing formation, wherein at least one of the slots extends from a side of a wellbore and is perpendicular to at least two substantially horizontal or inclined portions of the wellbore positioned in the hydrocarbon containing formation;providing heat to a second section of the hydrocarbon containing formation from one or more additional heaters placed in at least one of the slots;allowing the heat to transfer from the heaters to the second section of the formation; andproducing additional hydrocarbons from the hydrocarbon containing formation. 11. The method of claim 10, wherein at least one of the additional heaters comprises an insulated electrical conductor. 12. A method of producing methane from a hydrocarbon containing formation, comprising: forming at least one wellbore in a hydrocarbon containing formation, the wellbore comprising at least two substantially horizontal or inclined portions, a first opening at a first position of the earth's surface and a second opening at a second position of the earth's surface;forming one or more slots in a portion of the hydrocarbon containing formation, wherein at least one of the slots extends from a side of the wellbore and is perpendicular to the at least two substantially horizontal or inclined portions of the wellbore;providing heat to a portion of the hydrocarbon containing formation from one or more heaters placed in at least a portion of one of the slots, wherein one or more of the heaters comprise one or more insulated electrical conductors;maintaining an average temperature in the portion of the formation below a pyrolyzation temperature of hydrocarbons in the section; andremoving methane from the hydrocarbon formation. 13. The method of claim 12, wherein the hydrocarbon containing formation comprises oil shale. 14. The method of claim 12, further comprising removing hydrocarbons having a carbon number between 1 and 5 from the portion of the hydrocarbon containing formation. 15. The method of claim 12, wherein the portion of the formation comprises coal. 16. The method of claim 12, further comprising providing a barrier around the portion of the formation. 17. The method of claim 12, wherein an average temperature in the portion of the hydrocarbon containing formation is below 230° C. 18.
