An apparatus that is usable with a well includes a gas lift valve and an isolation member. The gas lift valve includes a valve element that is located between an annulus and a passageway of a tubing. The valve element is adapted to selectively open and close to control fluid communication through the valve element. The isolation member is adapted to in a first state, isolate the valve element from at least one of the annulus and the passageway and in a second state, permit fluid communication between the valve element and the annulus or passageway.

Un appareil qui peut être utilisé avec un puits comprend une soupape de poussée de gaz et un élément d'isolation. La soupape de poussée de gaz comprend un élément de soupape qui est situé entre un espace annulaire et un passage d'un tube. L'élément de soupape est conçu pour ouvrir et fermer de manière sélective afin de commander la communication fluidique à travers l'élément de soupape. L'élément d'isolation est conçu pour, dans un premier état, isoler l'élément de soupape à partir d'au moins l'espace annulaire ou le passage et, dans un second état, permettre une communication fluidique entre l'élément de soupape et l'espace annulaire ou le passage.
