The U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has selected nine projects to receive funding to research new CO2 storage technologies devoted to intelligent monitoring systems and advanced well integrity and mitigation approaches through DOE’s Carbon Storage Program.

The Carbon Storage Program advances the development and validation of technologies that enable safe, cost-effective, permanent geologic storage of CO2. The program also supports the development of best practices for commercial implementation of carbon capture and storage technologies. The technologies being developed and conducted through the program will benefit the existing and future fleet of fossil fuel power-generating facilities and other industrial CO2 sources.

The selected projects concentrate on three research priorities: (1) Carbon Capture and Storage (CCS)-specific intelligent systems for monitoring, controlling, and optimizing CO2 injection operations, and (2) diagnostic tools and methods capable of characterizing borehole leakage pathways or fluid flow in existing wells; and (3) next-generation materials and methods for mitigating wellbore leakage

Project descriptions follow.

The University of North Dakota (Grand Forks, ND) will research intelligent monitoring system modules to automate CO2 storage site monitoring and simulation data, allowing site operators to more efficiently manage operations. Project partners are Computer Modeling Group, Schlumberger, Petroleum Technology Research Centre, and the CETER Group.
