Ballycatter Mech-1 Single Grip Mechanical Packer

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

The Ballycatter Mech-1 is a retrievable, compression-set mechanical packer designed for low-pressure production, casing integrity testing, and well intervention operations. Built with a long-stroke mandrel and a large bypass area, it allows unrestricted fluid circulation while running in hole. The bypass is controlled by a face-seal valve that automatically closes during setting, fully isolating the annulus once the packer is engaged.

Setting is achieved via a mechanical J-slot system using standard right-hand (or optional left-hand) rotation. Once the tool is positioned, applying set-down weight activates the slips and compresses the packing elements, sealing off the formation below. Retrieval is straightforward—lifting the tubing string engages the J-slot and reopens the bypass valve for safe circulation and recovery.

The Mech-1 features a rocker-type slip design for positive casing engagement and can be repositioned if required. Its straightforward operation, reliable sealing, and retrievability make it a practical solution for conventional production completions, casing leak diagnostics, and test operations where hydraulic setting is not required.

Ballycatter HP-6 High Angle Production Packer

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

The Ballycatter HP-6 is a compact, hydraulically set production packer designed for low to medium-pressure applications in high-angle and horizontal wells. With a short body length and no tubing movement required for setting, the HP-6 is ideally suited for tight-radius deviations, stacked completions, and coiled tubing operations.

It can be run in single or multiple packer installations with sequential setting in a single trip, reducing rig time and complexity.

Rated to 7,500 psi and tested in Q125 casing, the HP-6 features a straight-pull release mechanism that is fully isolated from hydraulic pressure, allowing low shear-out force even under full differential pressure.

Built-in bypass ports equalize pressure during retrieval, ensuring smooth release and reducing swab risk. The tool can be set using rig pumps, and its economical design allows for easy redress and reuse. Optional rotational release is available for added flexibility in challenging retrieval scenarios.

Engineered with materials and elastomers for hostile environments, the HP-6 delivers dependable performance in offshore operations, high-angle wells, and cost-sensitive completions requiring reliability without unnecessary complexity.

Ballycatter HP-3 High Angle Packer

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

The Ballycatter HP-3 is a hydraulic-set packer engineered for high-angle and deviated well applications, where conventional mechanical or wireline-set tools are not feasible. This packer is particularly suited for single or multi-zone completions, offering flexible deployment in complex well trajectories.

Unlike mechanical systems, the HP-3 requires no tubing movement to set. This enables full well control throughout the operation, as the tubing can be landed and the wellhead installed prior to circulating or displacing fluids.

Key Features:

• Reliable Setting Mechanism: Utilizes dual balanced pistons—one actuates downward to anchor the bi-directional slips, while the other moves upward to compress a three-element packing system. This simultaneous action ensures a secure set and pack-off.

• Three-Element Seal: The packing system uses dual-durometer rubber elements to ensure long-term sealing integrity across a range of downhole conditions.

• Slips & Housing: One-piece, bi-directional slips are housed in a shear-pinned chamber, protected by a full-diameter guide to prevent damage during deployment.

• Release Options: Features a dual-method release system:

• Straight pull via shearing of pre-set screws.

• Right-hand rotation (approx. 8 turns), followed by straight pull.

• Equalization & Retrieval: Built-in equalizing valve opens automatically during release to balance pressures and enable safe retrieval. A large-diameter bypass within the mandrel allows fluid to flow during retrieval, reducing swab effects on the packing elements.

The HP-3 is engineered for reliability, operational flexibility, and full well control—making it a practical choice for complex wellbore geometries.

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.

HPL-1 Hydraulic Set Retrievable Production Packer – Large Bore Design for Enhanced Performance

The HPL-1 Hydraulic Set Retrievable Production Packer is a large-bore, hydrostatic-set, double-grip packer, designed to optimize production, injection, and zonal isolation applications. Its expanded internal diameter provides increased flow capacity, reducing pressure drop and improving overall well efficiency. The packer is set using tubing pressure, eliminating the need for tubing manipulation and making it particularly effective in low hydrostatic head wells where conventional setting methods may be challenging. Once engaged, the multiple packing element system ensures a mechanically locked, high-integrity seal, sustaining pack-off force throughout its operational life.

To maintain wellbore stability, the hydraulic hold-down pistons engage after setting, preventing movement due to differential pressure. The body lock ring securely traps the setting force, ensuring that bottom-hole pressure fluctuations or tubing contraction do not compromise the seal. The large bore configuration makes the HPL-1 packer especially suited for high-volume production, deviated wells, and applications requiring unrestricted flow paths for enhanced reservoir performance.

For retrieval, operators can apply a straight upward pull or utilize the optional right-hand rotational release, depending on well conditions. The shear release mechanism enables controlled removal, minimizing downtime and reducing the risk of stuck tools. With its large-bore capability, secure hydraulic setting, and reliable retrievability, the HPL-1 packer is a high-performance solution for maximizing production efficiency, minimizing flow restrictions, and optimizing well completions.
