Drill in, rotate, and reciprocate long heavy liners

HEAT hybrid expandable anchoring technology is a premium system designed for heavy and long liner deployment in all types of wells and environments up to HPHT conditions. By enabling drill-in applications and rotation and reciprocation during cementing, the technology reduces trip time and enhances well stability.

Maintain liner top integrity and casing properties

The static mandrel delivers high burst, collapse, and tensile capacities typically found only in conventional hanger systems. The unique design of the HEAT technology uses the liner weight to aid in expanding the hanger. Bonded elastomeric seals on the hanger's expansion sleeve produce a fluid-tight seal when set in the host casing. Redundant metal-to-metal seals on the sleeves and mandrel ensure liner top integrity after expansion.

The high torque capability enables rotation even in challenging wellbore configurations. In addition, the lack of external components eliminates the risk of presetting.

A large fluid bypass also reduces formation surging and decreases trip time.
