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.

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.
