1. A method of treating a hydrocarbon containing formation in situ, comprising:

  • providing heat from one or more heaters to at least a portion of the formation;

    allowing the heat to transfer from the one or more heaters to a part of the formation, wherein one or more of the heaters comprise at least two heaters, and wherein superposition of heat from at least the two heaters mobilizes at least some hydrocarbons within the part of the formation;

    maintaining a pressure within at least a majority of the part of the formation above about 2.0 bar absolute; and

    producing a fluid from the formation comprising condensable hydrocarbons, wherein the condensable hydrocarbons within the fluid comprise an atomic hydrogen to atomic carbon ratio of greater than about 1.75.
