Abstract:
A method for accommodating thermal expansion of a heater in a formation includes flowing a heat transfer fluid through a conduit to provide heat to the formation and providing substantially constant tension to an end portion of the conduit that extends outside the formation. At least a portion of the end portion of the conduit is wound around a movable wheel used to apply tension to the conduit.
