9 5/8" Mech-2 Double Grip Mechanical Set Packer for 47-53.5 PPF Casing

Ballycatter Mech-2 Double Grip Mechanical Packer

Available sizes: 5”, 5 1/2”, 6 5/8”, 7”, 9 5/8”, and 10 3/4”

The Ballycatter Mech-2 is a retrievable, compression-set double-grip mechanical packer designed for applications where pressure differentials from below are anticipated, such as combined stimulation and production operations. Featuring opposing slips above and below the packing element, the Mech-2 ensures secure bi-directional anchoring within the casing under varying well conditions.

The tool incorporates a built-in hydraulic hold-down system located beneath the face-seal bypass valve, enabling it to resist upward forces during stimulation treatments. A unique “Differential Lock” mechanism utilizes pressure from below the packer to actuate a balance sleeve, generating additional downward force that maintains bypass valve integrity and ensures a reliable seal.

The Mech-2 is mechanically set using a long-stroke mandrel and a J-slot mechanism. Once positioned, right-hand rotation and applied set-down weight close the bypass valve, engage both slip sets, and compress the sealing elements. The formation below the packer is then fully isolated and accessible only through the tubing. To retrieve, the tubing is raised the full packer length, automatically re-engaging the J-slot and reopening the bypass for pressure equalization and circulation.

With its dual-grip design, hydraulic hold-down, and controlled setting and release process, the Mech-2 offers a robust and dependable solution for demanding applications requiring secure annular isolation and enhanced downhole stability.

5 inch K Storm Choke

Storm Choke® K safety valves are ambient-type, wireline retrievable valves with the largest flow area of all direct controlled safety valves on the market. They are ideally suited for high-volume, low-pressure wells. These valves are normally closed and pre-charged with a set dome pressure. When the well flowing pressure drops below the predetermined dome-pressure charge because of a rupture in flowline or surface equipment, the dome pressure and main valve spring close the valve, shutting in the well below the earth’s surface. This valve contains a detent mechanism to provide a positive snap-action closure at the predetermined disaster rate of the valve. Its bore is not restricted by a flow bean. The valve is designed to resist pressure surges. A metal-to-metal poppet valve and seat comprise the valve’s primary closure mechanism. The K valve is ideal for protecting wells with declining bottomhole pressure. This valve closes in situations where a pressure decline would not activate a valve with a flow bean. To reopen the valve, the operator must fully equalize pressure either by applying pressure in the tubing from the surface or by an equalizing prong. The valve will reopen when the tubing pressure acting on the internal piston area overcomes the dome charge.

HP-1 Hydraulic Set 9 5/8 inch Packer

The HPL-1 Large Bore Hydraulic Set Retrievable Production Packer is a high-performance isolation toolactivated using tubing pressure, eliminating the need for mechanical manipulation. When pressure is applied against an underneath plugging device, the hydraulic setting mechanism engages, compressing the multiple packing element system to create a secure seal between the tubing and casing. Designed for versatility, the HPL-1 is available in 7” and 9 5/8” large bore options, making it ideal for high-volume production and injection applications. This design allows the packer to be set at any depth, making it particularly effective in low hydrostatic head wells while ensuring well integrity after the tubing is in place, even in large-diameter casing environments.

Once set, the double-grip system secures the packer in position using hydraulic hold-down pistons and a body lock ring, preventing unwanted movement due to pressure fluctuations or tubing expansion. Themechanically locked setting force ensures that reductions in bottom-hole pressure or tubing contraction do not weaken the seal, providing long-term reliability in production, injection, and zonal isolation applications. With the 7” and 9 5/8” options, the HP-1 is well-suited for high-flow rate completions, offering exceptional sealing performance and operational efficiency in larger casing sizes.

To retrieve the packer, operators can apply a straight upward pull, or, if equipped with the optional right-hand rotational release, use torque combined with a shear release mechanism. This flexibility allows for efficient removal in both standard and deviated wells, making the HP-1 packer a versatile, high-capacity solution for a wide range of completion designs, including large-bore well systems requiring robust isolation and retrieval capabilities.

Safety Valve for Water Injectors 5.71 inch

The WI retrievable injection valve is a high-performance, high-flow rate injection valve. High throughput is achieved by a unique valve configuration that minimizes turbulent and potentially erosive flow. Operation is not dependent on a specific flow rate, pressure, or setting depth, thus negating the need for adjustment over time. The valve incorporates a metal-to-metal valve and seat energized by the combination of an integral spring and well pressure acting from below. The WI injection valve can be deployed on a wireline lock or through-tubing pack-off device, providing flexibility not available with alternative injection valve systems. As a result of the simple design with fewer parts, redress and repair costs are considerably lower than those for other injection valve systems. Applications The WI injection valve is primarily used in water injection applications as an alternative to conventional tubing or wireline-set safety valves. The valve is also commonly used as a retrofit solution in water injectors in which a tubing to annulus leak has occurred. The valve can be deployed below the leak point to eliminate uncontrolled annulus pressure increases when the injection stops. Features » Compatible with all known lock systems » Dedicated designs to suit Halliburton EB0 intervention packers » Enhanced internal flow profile » Simple design and construction » Flow-loop testing performed to establish pressure drop versus pump rate *information referenced from supplier catalog.

5" Mech-2 Double Grip Mechanical Set Packer for 15-18 PPF Casing

Ballycatter Mech-2 Double Grip Mechanical Packer


Available sizes: 5”, 5 1/2”, 6 5/8”, 7”, 9 5/8”, and 10 3/4”


The Ballycatter Mech-2 is a retrievable, compression-set double-grip mechanical packer designed for applications where pressure differentials from below are anticipated, such as combined stimulation and production operations. Featuring opposing slips above and below the packing element, the Mech-2 ensures secure bi-directional anchoring within the casing under varying well conditions.


The tool incorporates a built-in hydraulic hold-down system located beneath the face-seal bypass valve, enabling it to resist upward forces during stimulation treatments. A unique “Differential Lock” mechanism utilizes pressure from below the packer to actuate a balance sleeve, generating additional downward force that maintains bypass valve integrity and ensures a reliable seal.


The Mech-2 is mechanically set using a long-stroke mandrel and a J-slot mechanism. Once positioned, right-hand rotation and applied set-down weight close the bypass valve, engage both slip sets, and compress the sealing elements. The formation below the packer is then fully isolated and accessible only through the tubing. To retrieve, the tubing is raised the full packer length, automatically re-engaging the J-slot and reopening the bypass for pressure equalization and circulation.


With its dual-grip design, hydraulic hold-down, and controlled setting and release process, the Mech-2 offers a robust and dependable solution for demanding applications requiring secure annular isolation and enhanced downhole stability.

FRN 3-1/2 inch Subsurface Safety Valve WR

The FRN wireline-retrievable flapper valve, which is normally closed, is held open by hydraulic control pressure from the surface. The valve operates on a hydraulic-piston principle. To open, tubing pressure slightly higher than the well pressure below the closed flapper is applied. Once well pressure is equalized across the closed flapper, hydraulic pressure is applied to the piston, which pushes the flapper open. The flapper hinge assembly is designed so the force on the piston is not applied directly on the hinge pin. Upon loss of hydraulic pressure in the control line, the valve's large spring serves to lift the hydrostatic head of the control fluid. The flapper spring is designed to close the valve when the piston moves up past the flapper. Opening Prong Nose Seal The FRN valve uses the valve housing as the downstop for the opening prong. This metal-to-metal (MTM) interface is designed to prevent flow from passing between the valve housing and opening prong. The MTM interface isolates the flapper and seat from fluid flow while the valve is open. This design creates an MTM interface with the full force exerted by the hydraulic piston, minus the spring compression force, holding the two metal faces in contact. Radius of Curvature at Flow Entrance Halliburton conducted a study with various curvatures on the entrance to the valve. The study tested abrasive fluids flowing through different test subs and examined the resulting wear patterns. As a result, an optimum radius of curvature was determined and implemented on the valve housings of all wireline retrievable safety valves. Applications » New completions » Deep set » High pressure Features » High-strength rod-piston actuation » Non-equalizing flapper closure » Solid construction flapper made from bar stock » Spherical radius seat on flapper improves seal reliability » Sealing and seating surfaces are out of flow path of well production when valve is in open position » Designed for easy field servicing *information referenced from supplier catalog.
