GAS LIFT SERVICES GAS LIFT Gas lift is a type of artificial lift system that typically utilizes a high pressure gas source. Gas is injected down the annulus, through a gas lift valve into the tubing and produced up the tubing with the produced fluid. The injection gas aerates the fluid, decreasing the density of the fluid allowing it to flow to the surface. Gas lift is the most natural form of artificial lift. The primary purpose of a gas lift system is to reduce the pressure in the wellbore. Drawdown of this pressure allows the formation to feed into the wellbore which creates production for the well. There are two types of gas lift equipment: Conventional and Wireline Retrievable. The following pages will detail these systems and the equipment needed for each.

TUBING RETRIEVABLE VALVES All Priority valves are assembled in house meeting and exceeding the hightes industry standards. We design and build all of our valves to maintain performance and withstand any well condition. After the design is complete, the valves are placed in a temperature controlled setting and set to the proper pressure for each depth. As gas is injected into the casing and through the valves, the fluid level drops and casing pressure decreases. As the pressure in the casing decreases, the valves begin to close one at a time as the system works deeper into the well until operating at the deepest possible valve based on well conditions TUBING RETRIEVABLE VALVES 1.5″ TUBING RETRIEVABLE IPOC-2 (INJECTION PRESSURE OPERATED) VALVE 1.5″ SCREENED ORIFICE ASSEMBLY 1.5″ IPOCV-2 CHECK VALVE 1.0″ TUBING RETRIEVABLE IPOC-1 (INJECTION PRESSURE OPERATED) VALVE 1.0″ IPOCV-1 CHECK VALVE 1.0″ IPOC-1RF (INJECTION OPERATED REVERSE FLOW) VALVE 1.0 SCREENED ORIFICE ASSEMBLY .625″ TUBING RETRIEVABLE IPOC-3 (INJECTION PRESSURE OPERATED) VALVE CONTACT INFO Priority Energy LLC 5655 W.
