Abstract
The capability to recover the true seabed motion in seabed seismic is instrumental in obtaining the desired final data quality. Receiver and source position errors, orientation accuracy, coupling inconsistencies and, in the case of autonomous nodes, clock drift (non-linear part) and corruption of the node memory are some of the issues that can make the recorded data different than the actual seabed motion.
Data driven methods, which are routinely used to verify that these issue have been properly addressed during acquisition, suffer in the presence of acquisition gaps, which are caused by obstructions. We have developed and applied to synthetic and real data two methods that perform better than an industry standard method in the presence of acquisition gaps.
