Abstract
Methods and apparatus relate to systems and methods of recovering oil from a formation. In operation, a steam chamber develops as a result of steam injection into the formation and the recovery of fluids including the oil through a production well. An auxiliary well spaced in a lateral direction from the production well helps ensure development of the steam chamber as desired. The auxiliary well may enable heating of the formation through establishing an electric potential between the auxiliary well and the production well or by resistive heating of material forming the auxiliary well. Further, the auxiliary well may provide a flow path for solvent or gas injection to facilitate the recovery through the production well.
