The Cameron carbon storage wellhead system is part of our Sequestri™ carbon storage solutions portfolio. It improves performance by delivering significantly higher barrier integrity and life cycle durability under the demanding conditions of CO₂ injection compared with traditional oil and gas (O&G) wellhead systems.

Its sealing system is engineered to maintain full functionality across extreme temperature swings, from –112 to 250 degF [–80 to 121 degC], preventing loss of integrity during Joule-Thomson cooling events that commonly compromise standard wellhead sealing. The nonmetallic seals eliminate galling, corrosion, and degradation in CO₂ streams, resulting in more consistent long-term sealing performance and fewer interventions.

Compact, modular architecture reduces installation complexity, improves uptime, and supports seamless integration of fiber-optic lines (for monitoring pressure, temperature, and wellbore movement) without additional termination hardware, facilitating continuous measurement and verification aligned with Class VI* requirements. Together, this wellhead system's capabilities enhance operational efficiency, reduce NPT, minimize maintenance, and ensure superior wellbore integrity over the multidecade life cycle expected in CCS projects.

* The US Environmental Protection Agency (EPA) defines wells that are used to inject CO₂ into deep rock formations as Class VI wells.

• CO₂ injection wells on land, intended for long-term storage
• Monitoring wells that require continuous pressure and temperature sensing
• O&G wells repurposed for CCS operations
• Pilot and demonstration wells in early-stage sequestration projects
• Class VI regulatory environments requiring enhanced containment assurance
• Wells operating under extreme low temperatures or cyclic thermal loading from CO₂
• CCS projects using optical fiber or advanced downhole instrumentation for measurement, monitoring, and verification (MMV) on all annuli
