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.

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.

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 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.
