Dynamics of CO2 fluxes and concentrations during a shallow subsurface CO2 release

A field facility located in Bozeman, Montana provides the opportunity to test methods to detect, locate, and quantify potential CO 2 leakage from geologic storage sites.

Description
Summary:A field facility located in Bozeman, Montana provides the opportunity to test methods to detect, locate, and quantify potential CO 2 leakage from geologic storage sites. From 9 July to 7 August 2008, 0.3 t CO 2  day −1 were injected from a 100-m long, ~2.5-m deep horizontal well. Repeated measurements of soil CO 2 fluxes on a grid characterized the spatio-temporal evolution of the surface leakage signal and quantified the surface leakage rate. Infrared CO 2 concentration sensors installed in the soil at 30 cm depth at 0–10 m from the well and at 4 cm above the ground at 0 and 5 m from the well recorded surface breakthrough of CO 2 leakage and migration of CO 2 leakage through the soil. Temporal variations in CO 2 concentrations were correlated with atmospheric and soil temperature, wind speed, atmospheric pressure, rainfall, and CO 2 injection rate.
