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 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-5 Production Packer

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

The Ballycatter HP-5 is a hydraulically set, mechanically held, pressure-balanced production packer engineered for deep, high-pressure oil and gas applications. Designed to withstand bi-directional pressure differentials, it performs reliably in demanding environments such as deviated wells, stacked completions, and alternate zone installations. Its internal pressure balance system offsets downhole pressure fluctuations and reversals, maintaining integrity in the set position.

The HP-5 features upper and lower mechanical slips for secure engagement with casing under all well conditions, and its packing element system delivers a robust, pressure-enhanced seal. A unique body lock mechanism prevents pre-setting during deployment, keeping all components rigidly locked as a single unit while running in hole. This makes the HP-5 particularly effective in coiled tubing completions and high-angle installations.

The packer is released via a straight pull, with field-adjustable shear pins that are unaffected by differential pressure—allowing for flexible, operator-controlled release without tool disassembly. Compatible with a wide range of packer accessories, the HP-5 combines reliability, operational control, and downhole adaptability in a single robust solution for production and injection applications.

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.
