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

    allowing the heat to transfer from the one or more heaters to a selected section of the first hydrocarbon containing formation such that the heat pyrolyzes at least some hydrocarbons in the selected section;

    producing a blending agent from the selected section;

    producing a liquid from a section of a second hydrocarbon containing formation, wherein the second hydrocarbon containing formation is the same as or different from the first hydrocarbon containing formation; and
