Halliburton Co. added the CorrosaLock cement system, designed for CO2 storage, to its carbon capture, utilization and storage (CCUS) portfolio, the company announced Jan. 29.
The CorrosaLock is a composite of Portland-based cement and Halliburton’s proprietary WellLock resin system. Halliburton says incorporating resin generates a coating film on the composite surface that aids in bonding, reduces the system’s porosity and protects from CO2 degradation.
CCUS projects require long-term cement sheath integrity to permanently store CO2 underground, said Matt Lang, Halliburton’s vice president of cementing, in the company’s release.
“The significant permeability reduction and enhanced mechanical properties of our CorrosaLock system addresses those challenges for our customers and builds on Halliburton’s decades of experience designing annular barriers for corrosive environments,” he added.
