Carbon Capture & Storage - Jennifer Lewicki

Surface monitoring of CO2 migration

 

Key concerns associated with geologic carbon sequestration are surface leakage and storage verification. Dr. Lewicki carries out research on surface monitoring for detecting, locating, and quantifying potential surface CO2 leakage. Because there are no existing large-scale geologic carbon sequestration sites with surface leakage, the Zero Emissions Research and Technology (ZERT) project is carrying out an experiment at the Montana State University campus in which CO2 is released from a shallow horizontal well to create an artificial surface leak that can be studied by various teams. Dr. Lewicki is using accumulation chambers and the eddy covariance approach to map the surface leakage patterns at the site. Her work has led to improvements in interpreting surface flux data for the purpose of detecting surface leakage, and she is contributing to the experience base needed to inform development of surface monitoring approaches at actual geologic carbon sequestration sites.
