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.

Setting Mechanism

The Ballycatter WC-HP-2 Isolation Packer is hydraulically set, meaning it is activated using tubing pressure rather than mechanical manipulation. During deployment, the packer is run into the wellbore as part of a stacked packer system, positioned above another hydraulic retrievable packer.

Once in place, hydraulic pressure is applied through the tubing, which compresses the packing element system, forcing it outward against the casing wall. Simultaneously, the slips engage to anchor the packer in position, ensuring a secure, pressure-tight seal within the isolation zone. The hydraulic setting eliminates the need for tubing rotation, making it particularly effective for deviated wells or conditions where mechanical manipulation is restricted.

Once set, the packer remains mechanically locked in place, independent of trapped hydraulic pressure. This design ensures that differential pressures, wellbore fluid movement, or thermal expansion and contraction do not compromise the seal, maintaining long-term zonal isolation. The packer can be used for treatment, injection, or production operations, providing a stable isolation barrier between zones for efficient fluid control and optimized reservoir management.

Retrieval Mechanism

The WC-HP-2 Isolation Packer is retrieved using a straight-pull shear release system, which allows for efficient and controlled removal without requiring tubing rotation.

When an upward force is applied to the tubing, the shear-release pins disengage, allowing the packing elements to relax and the slips to retract. This mechanical release mechanism ensures that retrieval forces remain unaffected by differential pressure, providing operators with a predictable and reliable method for packer removal.

For added flexibility, the shear-release force can be adjusted before running the packer to accommodate different well conditions.

The compact, debris-resistant design of the packer facilitates smooth retrieval, even in doglegged or deviated wells, reducing the risk of tool sticking.

By providing a simple, efficient release mechanism, the WC-HP-2 minimizes rig time and operational costs, making it a practical and cost-effective solution for multiple-zone completions and casing isolation applications.
