SIDE POCKET MANDREL
TMP and TP Series Side Pocket Mandrel:
ACT forged pocket with integral tool discriminator, oval pipe, swages and orienting sleeves. Its orienting sleeve allows precise and proper alignment during the insertion of positioning devices / tools into the side pocket. Forged tool discriminator guides the proper diameter side pocket devices / tools into the mandrel pocket and deflects larger tools into the tubing bore to prevent damage to the positioning devices / tools. In Gas Lift applications, high pressure gas injected into the casing annulus flows through the ports of the pocket in the gas lift valve and into the tubing. The standard pocket in the ported between the seal bores to communicate with the casing annulus and the gas is circulated down the annulus through the gas lift valve into the tubing.These mandrels are used for tubing flow applications. Both TMP and TP series feature multiple porting variations for specific applications i.e. annulus flow, chamber lift, fluid injection water flood installations.
TMP and TPC Series Side Pocket Mandrel:
These mandrels are used in annulus flow applications in which a snorkel functions as an exhaust port. Snorkel located at the bottom of the side pocket, extends downward into casing annulus. The holes in the mandrel side pocket directly communicate with the tubing. High pressure gas injected into the tubing flows through the port between the packing bores into the pocket of the mandrel, then through the ports into the gas lift valve, downward through the snorkel and then finally into the casing.
TMPE and TPE Series Side Pocket Mandrel:
These mandrels are mainly used in chamber lift applications. They have no ports in the side pocket for communication with the tubing. Instead of that, an exhaust port is located at the bottom of the side pocket. This port is extended downward into the casing annulus through a 1/2″ pipe connected to the top packer of a chamber lift installation. In gas lift application, high pressure gas injected into the casing annulus flows through the ports in the side of the mandrel, the through the port in the gas lift valve and finally downward to the exhaust port.
TMPS and TPS Series Side Pocket Mandrel:
These mandrels are used in single string, multi zone fluid injection water flood installations. The casing exhaust port located at the bottom of the side pocket is used to protect the casing from high velocity turbulence related with water flooding. In water flood operations, water injected into the tubing flows into the mandrel side pocket, through the water flood flow regulator valve and downward through the exhaust port. A non retrievable check valve can be attached directly to the exhaust port. A non retrievable check valve can be attached directly to the exhaust port to prevent back flow from the annulus when the water flood regulator valve is removed.
LATCHES
1 ½ inch RK and 1 inch BK-2 Latches are designed for installation in G-type pocket profile side pocket mandrels. They utilize a locking ring which is held in position by spring force. As the latch enters the side pocket profile, the locking ring moves up and into the recessed area of the latch. When the latch seats, the ring is positioned in the locking recess of the pocket. To retrieve the latch, a pin is sheared by upward force allowing the locking ring mandrel to move up and out of the way. The ring is then freed to disengage from the locking recess as the valve and latch are retrieved.
1 ½ inch RM Latches are designed for installation in A-type pocket profile mandrel. They have a set of spring- loaded locking dogs designed to move up into a recessed area on the latch core when run into the latch profile of the mandrel. The valve is lowered into the pocket until the No-Go shoulder is reached. The spring force moves the locking ring downward, forcing the dogs to move over and onto the large O.D. of the inner mandrel, thus locking the valve in place. To release the latch, a pin is sheared by upward force which allows the inner mandrel to move up and out of the way. The locking dogs are then free to return to the recess area as the latch and valve are retrieved.
PILOT – OPERATED GAS LIFT VALVES
DESCRIPTION
The ACT Conventional Pilot Valve (V&1 .1/2O.D) and Retrievable Pilot Valve(V0.0.) consists of a pilot section and a power section.This valve utilizes a pilot section to activate a power section. A sealed chamber, including a multiply monel bellow, contain a nitrogen pressure charge over a dampening fluid which provides the closing force necessary to maintain the pilot section in a normally closed position and an inconel spring provides the force necessary to maintain the power section normally in a closed position.
OPERATION
Injection gas first enters the pilot section of the valve and acts on the effective bellows area.When injection gas pressure exceeds the closing force (due to pre-charged nitrogen gas pressure in the bellows), the bellow compresses. lifting the pilot valve stem of I the seat to open the pilot section and thus allows gas to be injected on top of the power piston.The differential between injection gas pressure and production fluid pressure, working on the annulus area between the power piston and port areas overcomes the spring closing force of the power section piston.This differential pressure opens the power section, allows injection gas to flow through the valve, past the reverse flow check valve into the production fluid through the production conduit. When pilot section closes due to injection gas pressure drop, the injection gas pressure on top of the power piston bleeds down to production fluid pressure and the spring closes the power section.

APPLICATION
Pilot operated valves are used primarily for intermittent gas lift where large, instantaneous injection gas volumes between opening and closing injection gas pressure are desired. The pilot valve can also be used where intermittent lift is required but injection gas must be controlled by a choke to prevent surface gas system pressure fluctuations
CHEMICAL INJECTION NIPPLE C/W DUAL CHECK & RUPTURE CARTRIDGE (SINGLE / DUAL INJECTION PORT)
DESCRIPTION
ACT Chemical Injection Nipple represents a complete solution to any application requiring downhole chemical injection. At the heart of the chemical injection nipple is the dual check valve and rupture cartridge assembly. This allows the chemical injection nipple to be run in hole in a ‘blanked condition’ and selectively opened for injection, with the application of the required shear pressure. The optional control line by-pass facility allows encapsulated control lines to pass interrupted through the chemical injection nipple. The chemical injection nipple can be supplied with a variety of profiles to allow for the installation of many standard flow control devices, such as blanking plugs, checks and chokes. These optional profiles also allow installation of the specifically designed separation sleeve, which provides a secondary method of isolating the chemical injection flow path from the tubing.
FEATURES AND BENEFITS:
- Burst, collapse, tensile and torque ratings as good as end connection
- Compact, modular design
- Metal to metal sealing connections throughout
- Optional nipple profiles provide all the flexibility and benefits of flow control equipment
- Removable rupture cartridge allows full pressure and flow testing prior to running
- Rupture cartridge can be supplied with a variety of shear pressures to suit customer requirements
Optional by-pass facility permits installation and protection of encapsulated control lines
INJECTION PRESSURE OPERATED GAS LIFT VALVE
DESCRIPTION
ACT N Series Valves utilize a nitrogen charged dome and bellow configuration designed for either continuous or intermittent flow applications. These are especially suitable for use as unloading and operating valves in areas where high gas lift pressures are available. Since the charge pressure above the bellows is affected by temperature, it is important that the operating temperatures at the valve be known. These valves are available in both wireline-retrievable and conventional installations.
BENEFITS
Vibration protected, 3-ply monel bellow are designed to withstand hydrostatic pressure up to 5000 psi Nitrogen dome charge, acting on the O.D. of the bellow, permits bellows to expand uniformly without stacking, thus prolonging bellow’s life.
The multiple port size availability, makes this valve series appropriate for a wide range of operating conditions.
Reversible seat is also available in several different materials.

OPERATING PRINCIPLE
The dome nitrogen charge applied to the external area of the bellows provides the downward force, holding the valve on its seat. This dome pressure is preset at the reference temperature and corrected to operating temperature. The opening forces on the valve are the casing pressure acting on the internal area of the bellows (less the area of the seat) and the tubing pressure acting on the seat area. When the combined casing and tubing pressures are sufficient, the valve opens. Once the valve is open, it remains open until the casing pressure is reduced to the predetermined closing pressure. The spread (the difference between opening and closing casing pressure) is controlled by the tubing sensitivity of the valve. The larger the seat port area, the more tubing sensitive the valve is.
ACT HIGH PRESSURE GAS LIFT VALVE (1-1/2” OD TYPE N90H & N90RH)
ACT High Pressure Gas Lift Valve incorporates the concept of piston cylinder in the true sense, which was not present in old Gas Lift Valves available in the market. Bellow is protected in this new design against deformation and remains not only straight but its coil is also not over stressed against high pressure. Due to this the bellow’s life gets increased and valve functions in a predetermined manner.

ORIFICE VALVES
ACT O Series valves are designed for circulating operations and provide means for communication between the tubing and the tubing/casing annulus.
The ACT (Model PKO) retrievable single point injection gas lift orifice valves are used for continuous tubing flow gas lift installations. It is used to control the flow of gas between the casing annulus and the tubing at valve depth. The valve has a check dart controlled by a spring which does not allow the back flow of gas or well fluids. If the injection gas pressure in casing & tubing annulus at valve depth falls below the fluid tubing pressure, the fluid from tubing will try to flow back through the valve. Reverse flow through the valve is prevented by a check dart in the valve body. The check dart is closed by pressure from the tubing and will not allow passage of fluid until casing pressure is greater or equal than tubing pressure. This valve is available from 1/8” to 3/8” port sizes in 1/16” increments.
