Monitoring of Geological CO2 Sequestration Using Isotopes and PF Tracers

Performer: Oak Ridge National Laboratory

Project No: FWP-FEAA045


  • Provided geochemistry support for the design of the Frio brine injection pilots.

  • Provided all the baseline gas chemistry, and gas and brine isotope chemistry for both the Frio I and II pilot injection studies.

  • Completed assessment of brine isotope analysis, as well as gas chemistry and stable isotope analyses, for samples obtained post-Frio II injection. Results indicate that, by combining the geochemical and Perfluorocarbon Tracer (PFT) technologies, definitive tracking of the CO2 was possible.

  • Existing project results were published in numerous publications and conference presentations.
