    Abstract: A method for treating a tar sands formation is disclosed. The method includes heating at least a section of a hydrocarbon layer in the formation from a plurality of heaters located in the formation. A pressure in the majority of the section is maintained below a fracture pressure of the formation. The pressure in the majority of the section is reduced to a selected pressure after the average temperature reaches a temperature that is above 240 °C and is at or below pyrolysis temperatures of hydrocarbons in the section. At least some hydrocarbon fluids are produced from the formation.

    Abstract: A method for treating a tar sands formation includes providing heat to at least part of a hydrocarbon layer in the tar sands formation from a plurality of heaters located in the formation. Heat is allowed to transfer from the heaters to at least a portion of the formation. A pressure in the portion of the formation is controlled such that the pressure remains below a fracture pressure of the formation overburden while allowing the portion of the formation to heat to a selected average temperature of at least about 280 °C and at most about 300 °C. The pressure in the portion of the formation is reduced to a selected pressure after the portion of the formation reaches the selected average temperature.

    Abstract: 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.
