Packers, Hangers, Plugs, and Accessories

Ensure Isolation During Drilling and Completions Operations

Packers and plugs are run to hydraulically isolate the sections above and below the packer and to provide a mechanical anchor to prevent the packer from sliding inside the wellbore. In coiled tubing (CT) completion applications, the packer also holds the CT string in place.

Packers are set mechanically, hydraulically, or on wireline. The mechanical-set packer is set by applying either tension or compression on the packer. The hydraulic-set packer is activated by hydraulic pressure. The CoilTOOLS hydraulic set-packers can also be set on wireline.

The CoilTOOLS suite of packers includes the entire range of packers and plugs used in wellbore treatments, selective stimulation, water conformance jobs, tubing integrity testing, CT completions, straddle repair installations, temporary or permanent well abandonment, and more.

Whenever packers or plugs are run, the downhole hydraulic and mechanical situation must be known. The shear pin setting must be high enough to withstand the additional forces resulting from applied differential pressure, yet low enough to allow a safe release of the packer. An equalizing tool or unloader valve may be needed to safely unset the packers.
