Two New Extreme Torque Connections for North American Shale
North American operators continue to push laterals farther and demand more from their casing strings – higher torque, smoother running, and proven reliability that won’t slow down operations. To meet these evolving needs, Vallourec is introducing two new high‑torque connections engineered for shale: DWC/C‑XT and VAM® XTRA.
Both deliver step-change torque performance while maintaining the trusted running behavior, durability, and quality that operators expect. Designed in Houston, tested in-house, and manufactured across our U.S. facilities, these new offerings give operators more capability without changing their normal operations.
DWC/C XT: Extreme Torque with Buttress Compatibility
DWC/C-XT is the latest evolution of our proven DWC/C family, now offering the highest torque performance of any buttress connection on the market. It provides a cost-efficient option for operators who want more torque without moving to a premium connection and without giving up the versatility and flexibility of buttress threaded and coupled (BTC) accessories. This latest option delivers smooth running, clean breakouts, and easy remakes that field teams rely on, while maintaining the reliable sealability DWC/C is known for.
One major Permian operator applied its toughest internal test protocol and reported:
“The connection performed flawlessly in its sealing capacity and has been cleared for use in all of our onshore North American assets.”
Key advantages for shale operators:
- Extreme torque performance while maintaining buttress compatibility
- Available in production casing sizes and rated for 100% pipe-body performance
- Multi taper thread form for smoother running and multiple make ups and break outs
- Available in multiple coupling diameters for tight clearance designs
VAM® XTRA: Premium Shale Gas Performance for Extended Laterals
VAM® XTRA is our new premium threaded and coupled connection for ultra-high torque shale gas applications, especially extended laterals where operators need maximum capability and reliability.
A company man on a recent job noted that the additional operational torque proved valuable, as they needed the full rotational capability to get the casing to bottom. He also reported no changes in rig operations compared to their previous well design using VAM® 21 HT.
Why VAM® XTRA stands out:
- Ultra-high torque for casing rotation
- Proven gas‑tight sealability for production
- Popular VAM® hooked thread form for fast, smooth, self-aligning makeup
The redesigned shoulder geometry, simplified pin nose, reverse-angle shoulder, and machined ID transition deliver secured driftability and optimized torque transfer. VAM® XTRA is a dependable, shale validated premium connection that runs fast and performs under aggressive downhole conditions.
Smart Run: Ready at the Rig
DWC/C-XT and VAM® XTRA are both available with Smart Run, Vallourec’s ready-to-run solution with running compound applied, driftable open-ended protectors and digital pipe traceability.
Pairing these connections with Smart Run:
- Reduces rig time
- Improves running consistency
- Provides a digital tally with full life traceability
Proven in the Field
In early 2026, DWC/C-XT completed a successful installation in the Permian Basin with over 25,000 ft run, zero backouts, and no operational disruptions. This run utilized a slim coupling option of DWC/C-XT to fit the operator’s slim well design.
Within days of that run, two additional operators installed DWC/C-XT in the Mid Con and Rockies regions with the same smooth performance.
VAM® XTRA also achieved a successful first run with a major Haynesville gas operator, completing the installation without issues and demonstrating strong operational rotation performance.
Tested for the Realities of Shale
Both designs were qualified using Vallourec’s VAM® Shale Protocol, incorporating elements of API RP 5SF (2019) and API 5C5 (2017) to simulate shale specific loading scenarios.
- Fatigue cycling with high dogleg bending
- Up to 100 cycles of maximum internal pressure with and without tension to simulate stimulation stages
- Series B liquid and gas production sealability tests under high temperature and bending
- Final limit-load tests to confirm operational limits
Made in America for American Shale Plays
Both new connections are fully developed, tested, and manufactured in the United States.
- Designed by Vallourec R&D in Houston
- Tested at our VAM® Connection Technology Center
- Manufactured from cradle to gate in Ohio, Texas, or Oklahoma
For operators who prioritize domestic sourcing, shorter lead times, and high-quality manufacturing, Vallourec pipes and VAM® connections offer a fully American supply chain.
