CO2 Batch Experiments and Regional Spring Sampling Results
On January 7, 2013, Peter Berger presented a talk titled “CO2 Batch Experiments and Regional Spring Sampling.” This presentation showed preliminary results of experiments in which reservoir and seal rocks associated with carbon sequestration were reacted in vessels with brine and CO2 at pressures up to 3,000 psi. These experiments provide valuable data on the rates of chemical reactions in sequestration systems and are necessary to investigate reservoir and caprock integrity.
Also covered was the sampling of springs across the Illinois Basin. This effort establishes baseline data on saline discharge to ensure that any changes after the implementation of carbon sequestration projects can be compared with historical data. It was one of several talks at the Environmental Protection Agency (EPA) webinar titled “Integrated Design, Modeling, and Monitoring of Geologic Sequestration of Anthropogenic Carbon Dioxide to Safeguard Sources of Drinking Water.”
The presentation was given in Washington, DC, as part of a project review of an ISGS-led USEPA STAR (Science To Achieve Results) grant and included work by the coauthors of the talk: Lois Yoksoulian, Jared Freiburg, Shane Butler, Sam Panno, William Roy, and Keith Hackley.
