Calgary, Alberta (March 9, 2026) — Tenaris, in collaboration with Cenovus Energy and
Noetic Engineering, has completed a testing program aimed at advancing thermal well
design in Canada. The initiative explored new approaches to shallow well drilling and
thermal pad development, focusing on how specific premium connection designs perform in
high temperature operating conditions.
Traditionally, shallow well thermal drilling was accomplished using slant well designs, often
requiring large surface pad sizes and specialty rigs. As operators assessed alternate thermal
well architectures to improve efficiency and cost, a knowledge gap in understanding
connection integrity under high bending and fatigue loads was identified. This technical need
led to industry collaboration combining Cenovus’s operational insight, Noetic Engineering’s
long standing thermal expertise in testing protocols, and Tenaris’s connection technology
and physical research capacity, to evaluate these new conditions in a structured, data-driven
program.
Testing was agreed upon and executed at Tenaris’s R&D center in Veracruz, Mexico, using
the two most common intermediate thermal casing sizes – 9 5/8” and 11 3/4” – with
TenarisHydril Blue® connections. The program assessed thermal sealabilty performance
under extreme bending loads up to 25 degrees/30 metres and added in high stress low
cycle fatigue scenarios. This replicated demanding conditions anticipated for shallow,
vertical start thermal well designs, and operations such as rotation during cementing prior to
steam application.
“Cenovus approached this initiative as an opportunity to evaluate how connection
performance could support new well design concepts,” says Pablo Toy, Commercial VicePresident for Tenaris in Canada. “By working together, we generated data that reflects field
conditions and contributes to broader technical discussions on thermal well integrity.”
Findings from the program highlighted the robust design of the TenarisHydril Blue®
connection in the thermal space and opened the door for Cenovus to plan a vertical start
shallow well pad.
All findings from this joint research and testing project were presented by Cenovus, Noetic
Engineering and Tenaris, at the Society of Petroleum Engineers (SPE) Thermal Well
Integrity and Production Symposium in Banff, Alberta in December 2025. The session
highlighted the need for increased collaborative work and the role of structured testing as a
key element in engineered cost reduction projects.
With all full-scale testing phases complete as of December 2025, Tenaris now has additional
unique data and experience to guide future thermal well designs as part of a commitment to
support innovation in Canada’s evolving thermal oil industry.
