We present a case study of time-lapse seismic monitoring of CO2 injection by time delay tomography. During 550 days, 10.400 tonnes of CO2 were injected into a porous reservoir sandstone at 1100 m depth. Crosswell data were acquired before and after the CO2 injection. The estimated tomographic velocity image shows a clear time-lapse velocity anomaly on the order of -10 % below the CO2 injection well head.
