Tenaris’s coiled tubing facility has recently manufactured its longest and heaviest 2-5/8” OD string to date, delivering a new 88-metric-ton string for CUDD Pressure Control.
As wells grow deeper and laterals extend further, demand for longer strings, higher weight capacity, and enhanced durability continues to increase. When CUDD Pressure Control approached Tenaris with a request to design and manufacture an exceptionally long 2-5/8” OD BlueCoil® string for a special-order reel trailer to support extended-reach completion activities, the challenge was clear: the string would far exceed the Houston facility’s established manufacturing weight limits.
The volume of steel required for this order demanded an expansion of the facility’s accumulator and reel capacity before production could begin. Despite equipment and process-related constraints, the result was the successful completion of an 88-metric-ton string, the longest and heaviest heat-treated 2-5/8” OD coiled tubing string Tenaris has ever manufactured.
Standard strings for shale applications typically weigh between 55 and 60 metric tons. Any design exceeding 63 metric tons is classified as a “heavy string” at the coiled tubing facility.
“The Tenaris coiled tubing team successfully adapted to meet our customer’s exact requirements – delivering a new heavy design on time and to specification, all while surpassing the previous record for the longest BlueCoil® string we produced just last year," said Wenceslao Pigretti, Coiled Tubing at Tenaris. “From utilizing a specialized crane for lifting and loading to implementing a new internal material flow for heavy-string processing, this project showcases both the capabilities of the facility and the people behind it.”
The string has been shipped to Oklahoma and will begin operations in the Mid-Continent region.
