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 WC-HP-2 Isolation Packer is a hydraulic-set, single-string tandem packer designed for multiple-zone well completions.

Its primary function is to act as the upper packer in a stacked packer system, working in conjunction with a lower hydraulic retrievable packer to create a sealed isolation zone between them.

This allows for selective treatment, injection, or production within specific well intervals. Additionally, the WC-HP-2 packer can be used toseal off casing holes or perforations, providing an effective solution for low-pressure well applications.

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.

The Ballycatter WC-HP-2 Isolation Packer is a hydraulic-set, single-string tandem packer designed for multiple-zone well completions.

Its primary function is to act as the upper packer in a stacked packer system, working in conjunction with a lower hydraulic retrievable packer to create a sealed isolation zone between them.

This allows for selective treatment, injection, or production within specific well intervals. Additionally, the WC-HP-2 packer can be used to seal off casing holes or perforations, providing an effective solution for low-pressure well applications.

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.

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.

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.
