Halliburton: Innovating CCUS with new tech.

1 min read

TLDR: Halliburton Company has added the CorrosaLock ™ cement system to its growing carbon capture, utilisation, and storage (CCUS) portfolio. The system is designed for CO2 storage and incorporates a resin that generates a coating effect that aids in bonding. The result is enhanced cement sheath elasticity and shear bond strength, allowing the barrier to better withstand downhole forces during injection and provide increased anchoring force to the formation. The CorrosaLock system joins other technologies in Halliburton’s advanced CCUS portfolio.

Oilfield service company Halliburton has expanded its carbon capture, utilisation, and storage (CCUS) portfolio with the addition of the CorrosaLock cement system. The system, which is designed for CO2 storage, is a composite of Portland-based cement and Halliburton’s proprietary WellLock resin system. The incorporation of resin generates a film on the composite surface that creates a coating effect that aids in bonding. Resin also reduces the system’s effective porosity and forms an adhesive layer to help protect cement CO2 degradation. The result is enhanced cement sheath elasticity and shear bond strength that allows the barrier to better withstand downhole forces during cyclic injection and provide increased anchoring force to the formation when compared to conventional cement systems.

According to Matt Lang, Vice President of Cementing at Halliburton, cementing wells for CCUS presents unique challenges. The CorrosaLock system addresses these challenges by providing significant permeability reduction and enhanced mechanical properties. The system joins Halliburton’s other technologies in its advanced CCUS portfolio, including the WellLock resin system, ThermaLock cement, and CorrosaCem cement system.
