Large Bore Lock with Packoff

When isolation from wellbore pressures is required, we can offer seal bore protection using a large bore lock with pack-off. This will typically be used inside either a Hydraulic Safety Valve Landing Nipple or within a Tubing Retrievable Sub-Surface Safety Valve. This equipment has the advantage of locking positively into the target profile and can be designed to suit all third party completion equipment.

In addition to protecting the critical seal bore areas, an increased internal diameter is provided to enable larger intervention tools to pass through. When used in conjunction with a Hydraulic Landing Nipple the control line port is also sealed and isolated from wellbore pressure.
