Injection pressure operated gas lift valve and methods of use

A gas lift system for use within a well, the gas lift system comprising:

• a tubular positionable within the well;
• and
• an IPO gas lift valve positioned within the tubular and comprising:
• a dome assembly;
• a bellows system coupled to the dome assembly, and comprising:
• a liquid-filled sealed chamber;
• a piston positioned within the liquid-filled sealed chamber and dividing the liquid-filled sealed chamber into a dome side and a valve side;
• a first bellows assembly positioned within the dome side of the liquid-filled sealed chamber and in fluid communication with the dome assembly, wherein the first bellows assembly includes a first dome side bellow and a second dome side bellow, the first dome side bellow having a first dome side diameter that is less than a second dome side diameter of the second dome side bellow;
• and
• a second bellows assembly positioned within the valve side of the liquid-filled sealed chamber, wherein the second bellows assembly includes a first valve side bellow and a second valve side bellow, the first valve side bellow having a first valve side diameter that is less than a second valve side diameter of the second valve side bellow;
• and
• a valve assembly in fluid communication with the second bellows assembly and operable to shift the IPO gas lift valve between an open position and a closed position and comprising:
• a valve stem coupled to the piston and comprising a seal portion;
• a valve seat having an outlet and shaped to receive the seal portion of the valve stem when the IPO gas lift valve is in the closed position;
• and
• a check valve assembly coupled to the valve assembly.
