To learn more about this case study and how OLI’s solutions can enhance your carbon sequestration computational modeling.
Ensuring Class VI CO2 well integrity
Managing CO2 injection well integrity is critical under the U.S. Underground Injection Control (UIC) program and EPA’s 40 CFR Part 146 guidelines. OLI’s software offers advanced material selection and corrosion management software to ensure environmental safety and well integrity in Class VI wells for CO2 sequestration.
UIC CO2 well integrity guidelines
Underground Injection Control (UIC) for CO2 wells, governed by the EPA's 40 CFR Part 146, requires rigorous computational models for material selection and corrosion prevention. OLI software ensures compliance and well integrity, addressing common CO2 corrosion challenges to protect against environmental hazards in carbon sequestration projects.
Challenges in CO2 well management
Corrosion challenges in CO2 wells
Carbon sequestration projects face metallic material degradation risks due to the highly corrosive nature of CO2 in Class VI wells. Selecting the right materials and designing for corrosion resistance while adhering to EPA guidelines requires advanced modeling to prevent failure and protect environmental safety.
Corrosive CO2 environments
Class VI wells are designed for CO2 injection into deep rock formations, where it reacts with formation water. This interaction can produce corrosive species that degrade the metallic materials. Without rigorous modeling to predict these interactions, such environments can significantly compromise well integrity.
Material selection for longevity
Sub-optimal material selection can lead to premature failures due to corrosion. OLI optimizes material selection by considering the specific combinations of CO2 injection fluids and formation waters. This approach ensures compliance with EPA regulations and enhances the safety and longevity of operations.
Ensuring environmental protection
A well integrity breach can lead to environmental hazards, including ground water contamination. Effective corrosion modeling, risk prediction, monitoring, and management are essential for ensuring strict regulatory compliance and environmental safety.

Corrosion Simulation for UIC Guidelines
OLI corrosion models for Class VI wells
OLI’s advanced corrosion simulation models provide essential insights into material performance under various operating conditions, including shut-in states and changing temperatures and pressures during CO2 injection. Our comprehensive models can simulate a wide array of impurities found in CO2 injectates, their complex reactions and the resulting mixtures when combined with formation water. This capability enables the precise prediction of corrosion rates and the identification of high-risk corrosion scenarios, thereby ensuring the integrity of Class VI wells. Utilizing OLI technology, project engineers can effectively select materials that resist the corrosive environments created during CO2 injection, ensuring compliance with 40 CFR Part 145 guidelines while minimizing costs.
OLI Software for UIC Compliance
Proven success in Class VI well computational modeling
In a recent carbon capture initiative, we employed OLI software to assess corrosion rates for different alloys subjected to three distinct CO2 injection/formation water mixtures. These case studies are essential for engineers to understand the impact of impurities on corrosion mechanisms, offering crucial insights for material selection under specific operational scenarios. OLI's software suite is a powerful solution for predicting and managing corrosion risks, thus boosting the safety and efficiency of CO2 injection wells. By integrating these corrosion models into the permitting process, operators can not only ensure long-term asset reliability and regulatory compliance but also achieve cost reductions and enhanced operational efficiency.
