HETS® Hydraulic Expandable Tubular Systems
Flexible design options for well engineering - HETS integrates expandable tubulars with conventional well construction using direct hydraulic expansion of solid concentric tubulars downhole to achieve metal-metal contact with high interfacial pressure. HETS is quite unlike other systems, deployed on wireline, coiled tubing or drill-pipe, and uses standard-grade steel components. Expand conventional casing and tubing to create a liner hanger or tie-back; even expansion of heavy casing is achievable with HETS. For both construction and remedial well engineering, zonal isolation packers, casing patch, tieback and liner hanger custom designs are available.
The HETS product family offers a flexible set of well design and construction tools for TTD, deep, slim, extended and horizontal well construction, workover or repair.
An expandable steel isolation barrier or external casing packer.
Live well intervention with stainles steel internal expandable cladding for wireline, coil or drill-pipe.
Swage a metal-metal load-bearing gas-tight connection to an existing casing string downhole.
Expandable liner hanger solutions for tight clearance liner to casing completions and DWC (drilling with casing) applications.
HETS Live-Well Deployment Systems
Expandable solutions in live wells in coiled tubing or electric line - internal patch or zonal isolation barrier activation.
