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.

Abstract
A method for treating a relatively permeable formation containing heavy hydrocarbons in situ may include providing heat from one or more heat sources to a selected section of the formation. The heat provided to the selected section may pyrolyze at least some hydrocarbons in the selected section. A blending agent may be produced from the selected section. A portion of the blending agent may be adapted to blend with a liquid to produce a mixture with a selected property.
