Abstract:
A method for in situ production of energy from a hydrocarbon containing formation, comprising:providing heat from one or more heaters positioned in heater wells 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 such that the heat from the one or more heaters pyrolyzes at least a portion of the hydrocarbons in the part of the formation; producing pyrolysis products from the formation; providing at least a portion of the pyrolysis products to a reformer to generate synthesis gas; producing the synthesis gas from the reformer; providing at least a portion of the produced synthesis gas to a fuel cell to produce electricity, wherein the fuel cell produces a carbon dioxide containing exit stream; and storing at least a portion of the carbon dioxide from the carbon dioxide containing exit stream in a subsurface formation.
