He and Ne as tracers of natural CO2 migration up a fault from a deep reservoir
This paper shows for the first time that CO2 can be fingerprinted from source to surface using naturally occurring noble gases for both storage performance and regulation compliance at engineered CO2 storage sites. This technique has since been used to reject allegations of CO2 leakage from a storage site in Canada (http://planetearth.nerc.ac.uk/news/story.aspx?id=1120&cookieConsent=A), and is now being adapted for use as a natural tracer for monitoring of shale gas exploration and production. The research was funded by NERC “Towards a sustainable energy economy” programme consortium grant NE/C516428/1. Gilfillan was subsequently awarded a NERC fellowship (NE/G015163/1).
