Halliburton Company has announced the addition of the CorrosaLock cement system to its growing carbon capture, utilization and storage (CCUS) portfolio.
The CorrosaLock cement system, 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 against cement CO2 degradation. The result is enhanced cement sheath elasticity and shear bond strength that allows the barrier to withstand downhole forces during cyclic injection better and provide increased anchoring force to the formation compared to conventional cement systems.
“Cementing wells for CCUS presents unique challenges. These projects aim for permanent underground CO2 storage, which requires long-term cement sheath integrity. The significant permeability reduction and enhanced mechanical properties of our CorrosaLock system address those challenges for our customers and builds on Halliburton’s decades of experience designing annular barriers for corrosive environments,” said Matt Lang, VP, Cementing.
The CorrosaLock system joins the WellLock resin system, ThermaLock cement and CorrosaCem cement system as part of Halliburton’s CCUS portfolio.
