Corrosion resistant annular barriers and digital solutions that enable the construction of carbon capture storage wells.Talk to an expert
Removing CO2 from the atmosphere is critical to meet decarbonization targets. In CCS well construction, CO2 is injected into underground wells for storage. Re-purposing existing wells that were previously drilled or completed years ago presents significant risk due to lack of understanding of the viability of the annular seal. For underground storage of CO2, environmental regulators now require new wells to be constructed for CCS applications to increase likelihood of long term barriers in these highly corrosive environments.
Cementing a CCS 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 like downhole temperatures and pressures.
Halliburton has decades of experience designing annular barriers for corrosive environments. We tailor our technologies to meet the unique challenges required to achieve superior wellbore integrity in a range of CO2 environments using reduced Portland cement blends or non-Portland solutions, along with advanced well integrity software modeling.
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.
