As CCUS projects advance across the United States, developers and operators face a unique challenge: uncertain Class VI well permitting timelines combined with the need to mobilize quickly once approvals are granted.
In two separate U.S.-based CCUS stratigraphic and injection well projects, operators required duplex, super duplex, and nickel alloy OCTG but could not commit to traditional long-lead mill orders months, or even a year or more, in advance. They needed a partner capable of providing technical guidance, flexible supply strategies, and accelerated delivery once permits were approved.
CRA delivered exactly that, bridging the gap between regulatory uncertainty and execution readiness.
The Challenge: Executing Amid Class VI Permitting Uncertainty
Both projects involved CCUS stratigraphic test wells and injection wells requiring corrosion-resistant materials suitable for CO₂-rich environments.
The core challenge was not just technical, it was strategic:
Traditional mill lead times for duplex and super duplex OCTG can extend 12–14 months. For operators navigating regulatory uncertainty, committing that far ahead introduces commercial and logistical risk.
Both customers turned to CRA because they needed assurance that appropriate material would be available when the project moved forward.
CRA’s Solution: Technical Expertise + Material Readiness
CRA worked directly with the end users and their engineering teams to define material requirements based on environmental exposure, CO₂ content, and well design parameters.
Through multiple meetings, both virtual and in-person, CRA’s expert metallurgical team collaborated with the operators to:
The final solutions included combinations of:
Rather than relying solely on standard mill production, CRA implemented a hybrid supply model, leveraging:
This approach reduced delivery timelines to approximately 8–18 weeks, depending on configuration, dramatically shorter than standard mill lead times.
Collaboration at the Core
These projects were defined by alignment. CRA’s Operations, Commercial, Quality, Manufacturing, and Technical teams worked in lockstep internally, while maintaining continuous collaboration with customer engineering groups.
Importantly, the operators did not always know the exact alloy specification required at the outset. CRA’s metallurgical specialists provided material selection guidance based on environmental conditions, ensuring corrosion resistance, mechanical integrity, and long-term performance under CO₂ injection exposure. The result was not just supply, it was a technically validated solution delivered with execution flexibility.
The Result: Readiness Without Risk
By combining metallurgical expertise with supply flexibility, CRA enabled both operators to:
Rather than replacing traditional mill solutions, CRA served as a strategic bridge, ensuring projects could move forward confidently when regulatory timelines allowed.
Both engagements strengthened long-term relationships and reinforced CRA’s position as a trusted partner in the evolving CCUS market.
Conclusion
As CCUS development accelerates, regulatory timelines and environmental complexity require a different supply strategy. Operators need more than material—they need technical partnership, flexibility, and execution certainty.
CRA’s proven ability to deliver duplex, super duplex, and nickel alloy OCTG on accelerated timelines, supported by expert metallurgical experience and relationship-based collaboration, positions us to support CCUS projects at every stage of development. When Class VI permitting timelines are uncertain, CRA ensures material readiness is not. Contact CRA today for you CCUS solutions.
