Time-lapse processing of 2D seismic profiles with testing of static correction methods at the CO2 injection site Ketzin (Germany)

► The first two 2D seismic surveys that have been acquired at Ketzin are described. ► A novel pre-stack static correction is developed for time-lapse for processing. ► A comparison of 2D and 3D processing results is conducted. ► Time-lapse interpretation showed that no CO2 related signature is observable. ► Time-lapse AVO analysis confirmed this finding.
