Zusammenfassung:	Methods and systems for treating a hydrocarbon containing formation described herein include providing heat to a first portion of the formation from a plurality of heaters in the first portion, producing fluids through one or more production wells in a second portion of the formation, reducing or turning off heat provided to the first portion after a selected time, providing an oxidizing fluid through one or more of the heater wells in the first portion, providing heat to the first portion and the second portion through oxidation of at least some hydrocarbons in the first portion, and producing fluids through at least one of the production wells in the second portion. At least two of the heaters may be located in heater wells in the first portion. The second portion may be substantially adjacent to the first portion. The produced fluids may include at least some oxidized hydrocarbons produced in the first portion.
