Abstract
A method and system for producing hydrocarbons in situ from a heavy-oil and tar sand fixed bed, hydrocarbon deposit distributed substantially within a porous formation. The porous formation is disposed below a ground surface. The system includes at least one injection well drilled into the formation and spaced apart from at least one production well also drilled into the formation. A heated thermal-energy carrier fluid is circulated under pressure into the injection well, circulated under pressure through a hydraulic fracture in the formation. The hydraulic fracture is disposed between the injection well and the production well. The circulated carrier fluid mobilizes hydrocarbons in at least a portion of the hydrocarbon deposit in situ by heating the hydraulic fracture and surrounding formation and producing at least a portion of the mobilized hydrocarbons by flowing the carrier fluid with mobilized hydrocarbons through the production well and fractionating the hydrocarbons to generate at least two fluid fractures having differing chemical compositions.
