Snap latch tool is a mechanical setting tool used for setting Bridge Plugs and Cement Retainers. It comprises a snap latch mechanism for setting the tool.
By putting the weight on it, it latches in product for setting. This essentially allows the setting tool to function as a snap latch stinger sub which provides an upward stop as the tubing is raised. At this stop the valve is closed but the stinger sub seal is still in the bore of the retainer. At this position in the running string internal pressure test could be carried out. For releasing the tool, up strain and rotate it.
Features:
1. One trip system. Mechanically sets tool with rotation and
2. Up strain and functions as a stinger for subsequent cementing operations
3. Easily converted to set either Cement Retainers or Bridge Plugs.
4. Safe run in. Upper slip is securely locked in place and latch is solidly threaded into the body of the retainer
5. Snap latch feature latches into the retainer with set down weight and is released with tension.
6. Controls retainer valve. The stinger opens the sleeve valve with set down weight and closes it with up strain.
7. Tubing pressure test is possible with latch sleeve valve retainers by pulling up to close retainer valve prior to snapping out of retainer.
