An in situ process for treating a hydrocarbon containing formation is provided. The process may include providing heat from one or more heaters to at least a portion of the formation. The heat may be allowed to transfer from the one or more heaters to a part of the formation such that heat from the one or more heat sources pyrolyzes at least some hydrocarbons within the part. Hydrocarbons may be produced from the formation.
1. A method for treating a tar sands formation, comprising: providing heat from a first set of one or more heaters located in a first section of a hydrocarbon containing layer in the formation such that the heat provided from the first set of heaters to the first section mobilizes at least some hydr
1. A method for treating a tar sands formation, comprising: providing heat from a first set of one or more heaters located in a first section of a hydrocarbon containing layer in the formation such that the heat provided from the first set of heaters to the first section mobilizes at least some hydrocarbons in the first section;providing heat from a second set of one or more heaters located in a second section of the hydrocarbon containing layer such that the heat provided to the second section from the second set of heaters mobilizes at least some hydrocarbons in the second section;producing at least some fluids from the first section to create a pressure gradient such that at least some of the mobilized hydrocarbons in the second section flow into the first section; andproviding fluid in the first section to drive hydrocarbons to the second section. 2. The method of claim 1, further comprising controlling the pressure in the first section to control the flow of mobilized hydrocarbons from the second section to the first section. 3. The method of claim 1, further comprising producing the fluids from the first section when an average temperature in the first section is below a pyrolysis temperature of hydrocarbons in the first section. 4. The method of claim 1, wherein at least some of the fluids produced from the first section comprise hydrocarbons. 5. The method of claim 1, wherein at least some of the fluids produced from the first section comprise un-pyrolyzed hydrocarbons. 6. The method of claim 1, wherein at least some of the fluids produced from the first section include hydrocarbons from the second section. 7. The method of claim 1, wherein producing the fluids from the first section maintains a pressure in the second section below a fracture pressure of the formation. 8. The method of claim 1, further comprising increasing an average temperature in the first section above a hydrocarbon pyrolysis temperature after producing at least some fluids from the first section. 9. The method of claim 8, further comprising producing at least some pyrolyzed hydrocarbons from the first section. 10. The method of claim 8, further comprising pyrolyzing at least some hydrocarbons from the second section in the first section. 11. The method of claim 8, wherein the hydrocarbon pyrolysis temperature is about 225° C. 12. The method of claim 1, further comprising maintaining an average temperature in the second section below a hydrocarbon pyrolysis temperature. 13. The method of claim 1, wherein at least some of the heaters in the second set of heaters have larger heater spacing than at least some of the heaters in the first set of heaters. 14. The method of claim 1, wherein all of the heaters in the second set of heaters have larger heater spacing than all of the heaters in the first set of heaters. 15. The method of claim 1, further comprising adjusting the heat output of the heaters in the first set of heaters and the second set of heaters to control the heat distribution in the hydrocarbon containing layer. 16. The method of claim 1, further comprising providing steam in the first section to drive hydrocarbons to the second section. 17. The method of claim 1, further comprising turning on the second set of heaters in the second section a selected time after turning on the first set of heaters in the first section. 18. The method of claim 1, further comprising turning down or off the first set of heaters in the first section after hydrocarbons from the second section flow into the first section. 19. The method of claim 1, further comprising providing heat from a third set of one or more heaters located in a third section of the hydrocarbon containing layer such that the heat provided to the third section from the third set of heaters mobilizes at least some hydrocarbons in the third section, and producing at least some fluids from the second section to create a pressure gradient such that at least some of the hydrocarbons in the third section flow into the second section. 20. The method of claim 19, further comprising providing fluid in the third section to drive hydrocarbons to the second section. 21. The method of claim 1, further comprising providing fluid in the second section to drive hydrocarbons to the first section. 22. The method of claim 1, further comprising producing at least some fluids from the second section through a production well located in the second section. 23. A method for treating a tar sands formation, comprising: providing heat from a first set of one or more heaters located in a first section of a hydrocarbon containing layer in the formation such that the heat provided from the first set of heaters to the first section mobilizes at least some hydrocarbons in the first section;providing heat from a second set of one or more heaters located in a second section of the hydrocarbon containing layer such that the heat provided to the second section from the second set of heaters mobilizes at least some hydrocarbons in the second section, wherein at least some of the heaters in the second set of heaters have larger heater spacing than at least some of the heaters in the first set of heaters; andproducing at least some fluids from the first section to create a pressure gradient such that at least some of the mobilized hydrocarbons in the second section flow into the first section. 24.
