OVERVIEW

The patented Barracuda™ HEX-Hanger™ is a high expansion gauge hanger that can be installed anywhere in tubing or casing, allowing operators to securely anchor wireless telemetry gauges, memory gauges, fluid samplers, capillary and fiber optic lines (set/unset capability) and other downhole devices via slickline, digital slickline and wireline methods. The HEX-Hanger models service 2-3/8″ to 13-3/8″ tubing/casing sizes and are set by our Barracuda™ Electro-SET™, a battery-powered electro-mechanical setting tool.

The Barracuda was primarily developed to retrofit our SonicGauge™ Wireless Monitoring System in wells with no gauges or with a failed permanent downhole cabled gauge (PDHG), hence the technology’s matching slimline 1.31” body OD, which offers significantly less flow restriction than any other tool available.

The unique setting mechanism dislodges scale during the setting process and ensures slips are effectively engaged with the tubing wall. A force retention system ensures the tool’s gripping force is maintained even with significantly changing well conditions. Our unique gripper design can withstand loads of 2,000kg (4,400lbs) to 4,000kg (8,800lbs) in either direction.

INSTALLATION

• The Electro-SET-HEX-Hanger toolstring is run-in-hole via slickline to depth
• An onboard timer or wireless command activates the Electro-SET, expanding the HEX-Hanger grippers onto 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-Hanger via a shear-pin mechanism
• The Electro-SET is then pulled-out-of-hole and the onboard setting log is downloaded to confirm successful installation
