Abstract:
Stable isotope analyses provide a powerful tool to trace the fate of CO2 in the subsurface. Stable isotopes of injected CO2 can act as useful tracers in carbon capture and storage (CCS) because the CO2 itself is the carrier of the tracer signal and remains unaffected by sorption or partitioning effects. Laser spectrometers used in the field can help to improve our under-standing about processes in the subsurface. With this results we are increasing the applicability of reservoir safety and monitoring programs. Newly developed Thermo Fisher Scientific instrument Delta Ray Isotope Ratio Infrared Spectrometer (IRIS), for continuous stable isotope monitoring was used at the Ketzin pilot site in Northern Germany. We used it in order to get new insights into underground geochemical processes and subsurface migration of the CO2 plume.
