ABSTRACT:
Liquid is lifted from a well by a traction seal fluid displacement device which is moveably positioned within the production tubing, and which maintains a seal during movement. The traction seal device comprises a resilient flexible toroid shaped structure within outside surface which contacts the inner sidewall of the production tubing and an inside surface which contacts itself to establish seals to these contact points as the outside surface rolls in essentially frictionless contact with in the production tubing. The toroid shaped structure is moved within the production chamber by applying a pressure differential across it. The pressure source is preferably natural gas at formation pressure.
