OVERVIEW

The patented Barracuda™ HEX-Retainer™ is a high-expansion basket retainer mounted on the HEX-Hanger™ for zonal isolation and well abandonment. It provides a reliable anchoring platform for sand, proppant, cement plugs, and melted metal-alloy plugs such as Bismuth (BiSn). The slimline 2.13” OD ensures clearance through a 2-7/8” No-Go nipple and expansion in casing sizes up to 9-5/8”.

The HEX-Retainer is deployed in a single run using the Barracuda Electro-SET, a rechargeable battery-powered electro-mechanical setting tool, via slickline or wireline.

For metal-alloy plugs, the SonicGauge™ Wireless Monitoring System can be integrated into the toolstring to continuously measure and transmit long-term pressure data from below the barrier, ensuring barrier integrity over a multi-year duration.

INSTALLATION

• The Electro-SET-HEX-Retainer toolstring is run-in-hole via slickline or wireline to the selected depth
• An onboard timer activates the Electro-SET, expanding the HEX-Retainer grippers against the tubing/casing wall via a soft-set pre-compression mechanism, which provides high force distribution and engagement
• The Electro-SET is disengaged from the installed HEX-Retainer via a shear-pin mechanism that simultaneously releases the basket petals, allowing the basket to expand and seat against the tubing wall, sealing the annular space
• The Electro-SET is then pulled-out-of-hole and the onboard setting log is downloaded to confirm successful installation
• The HEX-Retainer can immediately be used as an anchoring platform for a cement plug or a melted metal-alloy plug such as Bismuth (BiSn)
