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.

The Ballycatter Model WC-ESP Straight Pull 4.5” Packer is a compact, hydraulic-set production packer optimized for ESP completions in 4.5” casing. It features a pass-through section for ESP power cables, allowing seamless electrical connectivity between the surface and the ESP unit below.

The single-mandrel design with Acner Array Packing Element ensures superior sealing integrity, even in high-pressure and high-temperature wells. Its bi-directional slip system resists pressure from both above and below, providing secure anchoring and preventing unwanted movement.

Setting is achieved hydraulically by applying tubing pressure, locking the packer in place for long-term well isolation. Retrieval is simplified through a straight pull mechanism, eliminating the need for complex downhole tools and ensuring fast, efficient removal in standard and deviated wells. Compatible with all major ESP cable pack-off and feed-thru devices, the WC-ESP Straight Pull 4.5” Packer delivers reliability and ease of operation in compact wellbore conditions.

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-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.
