Near-surface monitoring for the ZERT shallow CO_2 injection project

摘要

As part of a collaborative effort operated by the Zero Emission Research and Technology Center (ZERT), a series of two shallow releases of CO_2 was performed at a test site in Bozeman, MT. The purpose of the experiment was to simulate possible leakagescenarios from a carbon capture and storage operation in order to further develop and verify monitoring technologies used to characterize and quantify the release of CO_2. The project included collaboration with several research groups and organizations. Presented here are the results of soil-gas monitoring conducted by researchers from the National Energy Technology Laboratory, including CO_2 flux measurement, soil-gas analysis, perfluorocarbon tracer monitoring, and soil resistivity measurements. Together, these methods proved to be effective in detecting and characterizing leakage in the near-surface.
