Corrosion resistant annular barriers and digital solutions that enable the construction of carbon capture storage wells.
Talk to an expertCementing a CCUS well is challenging because CO2 in the presence of water can produce carbonic acid. Conventional Portland cement degrades in the presence of carbonic acid, potentially leading to a loss of well integrity. In CCS well construction, it is critical to design for traditional operational parameters, such as downhole temperatures and pressures.
Halliburton has decades of experience in corrosive environment barrier design. We tailor our technologies to meet the unique challenges required to achieve superior wellbore integrity in a range of CO2 environments. Risk mitigation is achieved with non-Portland cement designs, modified cement systems, or reduced Portland solutions, along with advanced well integrity software modeling.
Barriers that completely remove components that react with corrosive environments and reduce possible pathways for gas or fluid to enter the cement sheath over time.
Resin modified Portland barriers combine Portland cement and resin to provide a corrosion resistant cement sheath with enhanced elasticity and shear bond and lower permeability compared to conventional Portland systems.
Barriers tailored with additives that help lower permeability and reduce corrosion alteration in comparison to conventional Portland cement designs.
iCem® Service - Superior 3D modeling capabilities allow us to ensure accurate placement of our engineered cement systems and assure their ability to provide long term zonal isolation, even in the harshest CO2 environments.
WellLife® Service – Advanced software modeling capabilities that can ensure the optimum cement system to reduce the risk of damage to the cement sheath, and thereby prevent zonal isolation failure for the life of the well.
