abstract = "Time-lapse seismic surveys have been implemented for monitoring CO2 sequestration at Cranfield. Some of the observed misalignments between the time-lapse datasets could have resulted from seismic acquisition or processing errors. To address this, we applied a registration method to correct misalignment between time-lapse post-stack seismic datasets. Such misalignments also exist in time-lapse pre-stack datasets, leading to the application of the same registration method on the time-lapse pre-stack datasets. The application of registration on the pre-stack datasets demonstrates its effectiveness on successfully separating time shift from time-lapse pre-stack AVA datasets. The improved consistency in the data allows us to invert time-lapse pre-stack datasets to capture time-lapse elastic property changes, which can be reliably used for monitoring of CO2 plume.",
