5 Gas Lift Systems Gas Lift Systems GAS LIFT

Continuous Gas Lift Continuous Gas Lift Annular Tubular Flow Flow Gas is injected continuously into Gas is injected into the production the annulus. The gas travels tubing, which travels down the down the annulus, regulated tubing, regulated through a gas lift through a gas lift valve and valve and into the fluid column in the into the fluid column inside the annulus. The injected gas reduces tubing in the well. The injected the density of the fluid to a point so gas reduces the density of that maximum flow is realized from the fluid to a point where the the reservoir. This application is best reservoir pressure can push it suited for wells that have a reservoir to the production facility. This pressure that will support fluid to application is suited for most any surface, have a high PI, low GLR and well requiring artificial lift where are tubing size limited. The larger a supply of pressurized gas is flow area will allow higher fluid rates available. to be produced.

6 Gas Lift Systems Applications

Intermittent Gas Lift Gas Lift Chamber Intermittently, high volumes of gas Lift System are injected into the annulus of Intermittently, high volumes the well. The injected gas travels of gas are injected into the down the annulus, regulated annulus of the well. The injected through a large ported or pilot gas gas travels down the annulus, lift valve under the accumulated regulated through a gas lift fluid column, which is quickly valve and displaces the fluid in displaced to the surface. The goal an accumulation chamber and is to produce the well at the actual the tubing. The accumulation rate that the fluid enters the chamber allows for the capture wellbore from the reservoir. This of more fluid than tubing alone application is best for wells that and increases the volume of produce low volumes due to low liquid produced each cycle. This BHP or low PI. application is best for wells with low BHP and high PI.

7 Gas Lift Systems Gas Lift Systems GAS LIFT

Dual Well Gas Lift Gas Lift Side String Injection Gas is injected continuously Gas is injected down the side into a common annulus. The string, which runs parallel to gas travels down the annulus, the production tubing and regulated through gas lift valves communicated with the gas and into the fluid column inside lift mandrel in installation. The dual tubing strings in the well. injected gas travels down the side This application is for wells that string, regulated through a gas have more than one reservoir, lift valve and into the fluid column which has to be produced inside the tubing. The purpose independently of each other. of this application is to isolate the annulus from gas injection pressure. This application is best for wells with damaged casing and wells where gas has to be vented up the annular area.

Conventional Valves

CIPO-1.0 | CIPO-1.5

The CIPO is a conventional (tubing retrievable) injection pressure operated gas lift valve that comes in 1" or 1-1/2" O.D. This valve is primarily controlled by injection gas pressure. The valve is used to control gas pressure and its flow from the casing annulus into the tubing during gas lift operations. The valve is installed on a conventional mandrel. The valve is designed with a sealed chamber, including a bellows assembly that contains a nitrogen charge over damping fluid. The bellows serves as an interface between the dome pressure and injection gas pressure. The dome charge provides the closing force of the valve. When injection gas pressure exceeds the closing force, the bellows compress, lifting the valve stem off of the seat, allowing gas to be injected through the valve and into the tubing. The CIPO valve consists of a tail plug, bellows assembly with valve core and bellows, bellows housing, stem with tungsten carbide ball, seat housing, floating seat and nose with reverse flow check dart with optional choke sizes. The valve is constructed of premium materials for corrosion resistance in wells with high concentrations of H2S and/or CO2. Elastomeric material for the valve is available for standard and special service.

Features: • Stainless steel or premium material • Three-ply monel bellows • Mechanical stop prevents bellows over stoke. • Viscous fluid shear dampening prevents bellow fatigue and stem pounding • Tungsten carbide ball and stem assembly • Replaceable floating monel seat (also available in tungsten carbide material) • Silver brazed bellows connections

Check Valves

CVIPO-1.0 | CVIPO-1.5 | CVIPO-1.0RF

The CVIPO is a conventional (tubing retrievable) check valve that comes in 1" or 1-1/2" O.D. The check valve is installed externally on conventional mandrels and chemical injection subs. Reverse flow checks prevent gas and fluid flow from the tubing back into the casing annulus. In operation, the reverse flow check valve utilizes a dual seating system. A soft seal ring is contacted first by the check dart and as differential pressure increases a metal-to-metal contact acts as a secondary seal. The CVIPO check valve consists of a check housing, seals, check dart and spring. The check is constructed of premium material for corrosion resistance in wells with high concentrations of H2S and/or CO2. Elastomeric materials for the valve are available for standard service and special service to suit individual well conditions.

Features: • Stainless steel or premium materials • 5,000 psi test pressure • Nickel alloy X-750 spring • Compatible with other industry standard conventional (tubing retrievable) mandrels • CVIPO check is required when utilizing flow with a screen orifice • CVIPO-1.0RF is for use in concentric mandrels and reverse flow applications

Wireline Retrievable Lateral Discharge Regulators & Mandrels

RWF-1.0 RWF-1.0

The RWF-1.0 is a wireline retrievable waterflood regulator. This regulator is designed to operate in industry standard side pocket gas lift mandrels with a 1" I.D. pocket. The regulator consists of a nose, orifice cap, spring, seat, cone and flow barrel.

Water enters the regulator through the nose, passes through the orifice cap and seat past the cone and exits laterally through the flow barrel.

The regulator is a normally open device that requires a minimum of 200 psi differential pressure to become operational. The differential pressure is required to overcome a pre- determined spring resistance that is holding the seat away from the cone. As the spring resistance is overcome the seat moves toward the cone holding the rate allowed to pass relatively constant regardless of the injection pressure.

When using an orifice valve to do the same type of operation, the injection rates will vary greatly with the changing differential pressure across the orifice. The rates will remain relatively steady through a regulator.

Features: • Available in stainless steel, monel or CRA material • Tungsten carbide cone • Easily calibrated

Wireline Retrievable Chemical Injection Valves

RCI-1 RCI-1 The Lufkin RCI-1 wireline retrievable chemical valve is a 1" O.D. valve used to control the amount of chemicals or fluids injected into the tubing to control corrosion in wells, treat paraffin, salt and/or hydrate formation. The valve is designed with a nickel alloy spring, which provides the closing force of the valve. The compression spring allows for setting operating differential pressures of 500 to 4,000 psi. The spring controlled test rack opening pressure is easily adjusted from outside of the valve without the need of disassembly. The spring-loaded operation of the RCI-1 valve allows accurate functioning of the valve regardless of well temperature. The RCI-1 valve is available with stem and seat size of 1/8", 3/16" and 1/4". The RCI-1 valve consists of a seat housing, spring and spring housing, setting and locking screw, stem with tungsten carbide ball, adapter and check housing with reverse flow check dart. The valve is available in either stainless steel or nickel alloys for corrosion resistance in wells with high concentrations of H2S or CO2. Elastomeric materials for the valve are available for standard service or special service to suit individual well conditions. In operation, the operator can control chemical/fluid flow into the tubing at valve depth. Chemical/fluid volumes, cycles and pressures can be regulated by the operator from the surface. The chemical or fluid is pumped from the surface down a capillary tube. The tube is connected to the chemical injection side pocket mandrel which communicates directly to the pocket. The valve can also be installed in industry standard gas lift side pocket mandrels and the chemical or fluid injected into the well’s annular area. In this case the chemical or fluid enters the side pocket’s entry ports and enters the valve.
