Patent ID: 8276673

Claim:
A gas lift system for removing liquid from a wellbore, the system comprising: a first tubing string positioned within the wellbore; a second tubing string disposed within the first tubing string, the second tubing string movable between a first position and a second position, an annulus being present between the second tubing string and the first tubing string; an aperture positioned in the first tubing string; a sleeve slidingly disposed around a portion of the second tubing string; a port disposed in a wall of the second tubing string such that the port is substantially covered by the sleeve in the first position and is substantially uncovered in the second position to permit fluid communication between an inner passage of the second tubing string and the annulus; and a sealing member operatively associated with the aperture to allow fluid communication between the wellbore and the annulus when the second tubing string is in the first position, the sealing member substantially inhibiting fluid communication through the aperture when the second tubing string is in the second position.
