Abstract:
1. A method, comprising: providing heat from one or more heaters to at least a portion of a first relatively permeable formation; allowing heat to transfer from one or more of the heaters to a part of the first relatively permeable formation such that the heat reduces the viscosity of at least some hydrocarbons in the part of the first relatively permeable formation; producing a first mixture from the part of the first relatively permeable formation; allowing heat to transfer from one or more of the heaters to a part of a second relatively permeable formation such that the heat pyrolyzes at least some hydrocarbons in the part of the second relatively permeable formation; producing a second mixture from the part of the second relatively permeable formation; and blending at least a portion of the first mixture with at least a portion of the second mixture to produce a third mixture comprising a selected property.
