Executive Summary
Optimized for Circulation and Retrieval
Designed for operations where circulation and clean retrieval are critical, the Ballycatter Mech-1 features a large bypass port controlled by a face-seal valve.
The bypass stays open while running in, allowing unrestricted flow, and closes during setting to ensure full pack-off. When released, the valve reopens automatically, enabling safe, efficient recovery without swabbing or formation pressure buildup.

Detailed Description
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.
