Patent ID: 8359167

Claim:
A method comprising: receiving, at a processor, first data representative of a first measured carbon dioxide (CO 2 ) concentration and of a first measured oxygen (O 2 ) concentration at a first measurement location; determining, by the processor using input data comprising the first data, that the measured carbon dioxide concentration at the first measurement location is elevated relative to a baseline carbon dioxide concentration due to escape of carbon dioxide from a source associated with a carbon capture and storage process, the determining comprising accounting for observed variability in the first measured carbon dioxide concentration expected to be attributable to one or more of respiration or photosynthesis of living organisms, combustion of fossil fuels, combustion of biofuels, or combustion of biomatter in a local vicinity of the first measurement site, the accounting for comprising detecting a change in a temporal correlation between the first measured carbon dioxide concentration and the first measured ox :en concentration at the first measurement location; and promoting a result indicating possible escape of carbon dioxide from the source.
