Heating tar sands formations to visbreaking temperatures
WO 2008051822 A3
A method for treating a tar sands formation is disclosed. The method includes heating at least a section of a hydrocarbon layer in the formation from a plurality of heaters located in the formation. The heat is controlled so that at least a majority of the section reaches an average temperature of between 200 C and 240 C, which results in visbreaking of at least some hydrocarbons in the section. At least some visbroken hydrocarbon fluids are produced from the formation.
