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.

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.

HPL-1 Hydraulic Set Retrievable Production Packer – Large Bore Design for 9 5/8” Casing

The HPL-1 Hydraulic Set Retrievable Production Packer is a large-bore, hydrostatic-set, double-grip packer engineered for 9 5/8” casing, providing enhanced flow capacity and efficient wellbore isolation for production, injection, and zonal isolation applications. Designed to maximize flow efficiency while maintaining well integrity, this packer is set hydraulically by applying tubing pressure, eliminating the need for mechanical tubing manipulation. The expanded internal diameter minimizes flow restrictions, making it an ideal solution for high-rate production and injection wells. Once set, the multiple packing element systemensures a mechanically locked, long-lasting seal, maintaining pack-off force throughout its operational life.

To prevent movement under differential pressure, the hydraulic hold-down pistons engage after setting, while the body lock ring secures the setting force, ensuring bottom-hole pressure variations or tubing contraction do not affect the seal. The large bore design allows for unrestricted flow paths, improving overall reservoir performance and artificial lift system efficiency. This makes it particularly valuable in ESP, gas lift, and other high-flow applications, where maintaining maximum production rates is critical.

For retrieval, operators can use a straight upward pull or an optional right-hand rotational release for controlled removal, reducing the risk of stuck tools and minimizing intervention time. With its high-capacity flow path, secure hydraulic setting, and efficient retrievability, the HPL-1 packer for 9 5/8” casing is an optimal solution for operators looking to enhance well performance, reduce pressure losses, and maintain long-term well integrity.

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.
