Cl- and Br-isotopes as new tracers



This project corresponds to Task 2 of the Research Program on the CO₂ Geological Storage, a partnership between IPGP, Total, Schlumberger and ADEME. Its objective is to precise the potential of using Cl- and Br-isotopic compositions of Cl and Br dissolved in formation water as tracers of transport within formation waters.

Laboratory experiences are being undertaken in collaboration with IFPEN, and the site for Decatur CO₂ geological (Illinois) is studied in collaboration with our colleagues from the USGS.
