Abstract
In one embodiment, a COleak detection instrument detects leaks from a site (e.g., a COsequestration facility) using rapid concentration measurements of CO, Oand optionally water concentration that are achieved, for example, using laser spectroscopy (e.g. direct absorption laser spectroscopy). Water vapor in the sample gas may not be removed, or only partially removed. The sample gas may be collected using a multiplexed inlet assembly from a plurality of locations. COand Oconcentrations may be corrected based on the water concentration. A resulting dataset of the COand Oconcentrations is analyzed over time intervals to detect any changes in COconcentration that are not anti-correlated with Oconcentration, and to identify a potential COleak in response thereto. The analysis may include determining eddy covariance flux measurements of sub-surface potential carbon.
