A method for treating a tar sands formation (32) in situ includes providing heat from one or more heat sources (30) to a portion of the tar sands formation. The heat may be allowed to transfer from the heat source(s) to a selected section of the formation to pyrolyze at least some hydrocarbons within the selected section. A mixture of hydrocarbons of a selected quality may be produced from the selected section by controlling production of the mixture to adjust the time that at least some hydrocarbons are exposed to pyrolysis temperatures in the formation.
