Method for treating a hydrocarbon containing formation are described herein. Methods may include providing heat to two or more first sections of the formation with one or more first heaters in two or more of the first sections. The provided heat may mobilize first hydrocarbons in two or more of the first sections. At least some of the mobilized first hydrocarbons are produced through production wells located in two or more second sections of the formation. The first sections and the second sections are arranged in a checkerboard pattern. A portion of at least one of the second sections proximate at least one production well is provided some heat from the mobilized first hydrocarbons, but is not conductively heated by heat from the first heaters. Heat may be provided to the second sections with one or more second heaters in the second sections to further heat the second sections.
The invention claimed is: 1. A method for treating a hydrocarbon containing formation using a checkerboard pattern, comprising: providing heat to two or more first sections of the formation with one or more first heaters in two or more of the first sections such that the provided heat mobilizes fir
The invention claimed is: 1. A method for treating a hydrocarbon containing formation using a checkerboard pattern, comprising: providing heat to two or more first sections of the formation with one or more first heaters in two or more of the first sections such that the provided heat mobilizes first hydrocarbons in two or more of the first sections; producing at least some of the mobilized first hydrocarbons through production wells located in two or more second sections of the formation, the first sections and the second sections being arranged in a checkerboard pattern, the checkerboard pattern having at least one of the first sections substantially surrounded by three or more of the second sections and at least one of the second sections substantially surrounded by three or more of the first sections; wherein a portion of at least one of the second sections proximate at least one production well is provided some heat from the mobilized first hydrocarbons but is not conductively heated by heat from the first heaters; and providing heat to the second sections with one or more second heaters in the second sections to further heat the second sections. 2. The method of claim 1, further comprising heating second hydrocarbons in the second sections such that at least some of the second hydrocarbons are mobilized, and producing at least some of the mobilized second hydrocarbons from the second sections, wherein at least some of the hydrocarbons in the mobilized second hydrocarbons were initially located in the second sections. 3. The method of claim 1, further comprising transferring heat to the second sections by allowing the mobilized first hydrocarbons to flow from the first sections to the second sections. 4. The method of claim 1, wherein at least some heat from the mobilized first hydrocarbons is convectively transferred to the portion of the second section of the formation proximate the production well. 5. The method of claim 1, wherein the one or more first heaters conductively heat the first sections. 6. The method of claim 1, wherein the one or more second heaters conductively heat the second sections. 7. The method of claim 1, wherein the provided heat increases the permeability of at least one of the first sections and/or at least one of the second sections. 8. The method of claim 1, wherein the provided heat pyrolyzes at least some hydrocarbons in the first sections and/or the second sections. 9. The method of claim 1, further comprising dewatering at least one of the first sections and/or at least one of the second sections prior to providing heat to the formation. 10. The method of claim 1, wherein the volume of at least one of the first sections is between about 70% and about 130% of the volume of at least one of the second sections. 11. The method of claim 1, further comprising injecting a fluid into the first sections to move at least some of the first hydrocarbons into the second sections. 12. The method of claim 1, wherein superposition of heat from the first heaters does not overlap a portion of at least one of the second sections proximate at least one production well. 13. The method of claim 1, further comprising controlling a temperature of a portion of at least one of the second sections proximate at least one production well so that the temperature is at most about 200° C. 14. The method of claim 1, further comprising reducing or turning off production in at least one production well in at least one of the second sections when a temperature in a portion proximate the production well reaches a temperature of about 200° C.
