LONDON — Engineering group Hunting has a collaboration agreement with CRA-Tubulars BV to pursue energy transition opportunities in North America.
The agreement gives Hunting access to CRA's Titanium Composite Tubing (TCT) technology and will employ Hunting’s oil country tubular goods (OCTG) connection technology to target carbon capture, utilization and storage (CCUS) and traditional corrosion-resistant OCTG applications.
CRA has developed its tubular technology for the upstream oil and gas industry and sees it as an enabler for CO2 sequestration projects worldwide.
TCT is lightweight and said to offer a superior anti-corrosion performance for production and injection wells in corrosive environments, handling the dual challenges of CO2 corrosion and hydrogen sulfide.
It is made from aerospace grade carbon fiber and titanium, and it is said to perform well in the cryogenic low-temperature environments associated with CO2 injection wells, avoiding embrittlement and cracking.
Its design is said to allow TCT to endure for the well’s entire lifespan, de-risking downhole tubing integrity challenges associated with the level of water and other contaminants that remain in the CO2 injection stream after the filtering process or migration into the well from the reservoir.
Various major operators are said to be assessing the development with recognition last year in the Shell Game-Changer program.
Hunting/CRA’s collaboration agreement is for an initial five-year period and provides exclusive TCT marketing, distribution and manufacturing rights in the North America region for application to oil and gas and CCUS.
Hunting will offer end users the option of deploying the composite tubing solution with conventional OCTG premium connection technology, including its SEAL-LOCK connections.
