摘要： Embodiments include providing a gas lift system comprising production tubing disposed within a wellbore, the production tubing capable of allowing fluid flow in a first direction from outside the production tubing through a wall of the production tubing to inside the production tubing to introduce a gas into the bore of the production tubing, while preventing fluid flow in a second direction from inside the production tubing through the wall of the production tubing to outside the production tubing. In one aspect, fluid flow in the second direction is prevented by operation of at least two valve members disposed within a side pocket of a side pocket mandrel in the production tubing. At least one of the valve members is capable of preventing fluid flow in the second direction even when the other valve member is removed from the wellbore or is at least partially inoperative.
