Abstract
A method and apparatus associated with producing hydrocarbons. In one embodiment, the apparatus comprises at least one heating element that is disposed in a chamber with actuator material. A member is also partially coupled to the chamber. The member is configured to extend to a first configuration when the at least one heating element converts at least a portion of the actuator material from a first phase to a second phase and contract to a second configuration when the actuator material converts from the second phase to the first phase.
