Halliburton launches XTR CS injection system to optimise CCUS performance

Halliburton has launched the XTR CS injection system, a wireline-retrievable safety valve solution engineered for CO₂ injection in carbon capture, utilisation, and storage (CCUS) wells

Operators face unique challenges in CCUS environments, including ultra-low temperatures and the need for reliable flowback prevention. The system addresses these challenges with a depth-insensitive design that can be installed at any point in the wellbore, delivering reliable performance with high injection rates and smooth flow. This eliminates concerns about hydraulic fluid mobility and reduces planning complexity.

The system can be used as a primary or contingency safety valve or as a deep-set reservoir fluid-flowback prevention device. Unlike traditional surface-controlled wireline valves, the XTR injection system’s non-elastomeric design helps minimise leak paths and eliminate reliance on hydraulic operation systems. This system remains at steady performance at any setting depth, to simplify operations and inventory management.

A large flow area, combined with low opening pressure, promotes smooth flow and supports high injection rates with minimal pressure drop. The proprietary anti-throttling mechanism helps keep the valve fully open during injection, reducing wear and extending service life. The self-cleaning design incorporates integrated bypass ports and optimised poppet geometry to minimise debris buildup and erosion. For added flexibility, wireline retrievability allows easy retrieval and replacement, supporting contingency planning when needed.

The valve features an anti-chatter mechanism to extend service life while meeting API 14A standards for safety and compliance.

The rigorous CS qualification programme ensures the system’s operational integrity and ability to withstand harsh CCUS environments.

The injection system can be tailored for specific injection media and fluid properties, offering low opening force, minimal pressure drop, and a wide range of injection rates. To extend operational life, high-velocity flow is directed away from seal areas, and a novel anti-throttle feature reduces valve wear, maximising system reliability.

Maxime Coffin, vice president, Halliburton Completion Tools said, “The XTR CS injection system expands Halliburton’s Completion Tools technology leadership in low-carbon technology solutions, allowing operators to maximise CCUS well performance. This technology helps ensure reliability and flexibility in harsh environments, allowing operators to inject CO₂ efficiently and safely.”
