Acquisition Footprint Removal from Time Lapse Datasets

Water layer variations and acquisition differences are two important factors that introduce time shift or amplitude artefacts in time-lapse datasets. These artefacts are correlated with the acquisition geometry and can be seen as stripes along the shooting direction. For this reason it can be desirable to use acquisition geometry information as a guide to solve for these variations. In this paper, a novel inversion scheme algorithm guided by acquisition parameters is introduced to correct for footprints usually seen on offset planes. These corrections can be static, that is no change across offset, or when water velocity changes the corrections can be dynamic and therefore vary across offset accordingly.
