Abstract
P170 MULTIPLE REMOVAL IN THE NORWEGIAN SEA – A COMPARISON OF METHODS. Summary 1 Removal of free-surface multiples from seismic reflection data is an essential pre-processing step before seismic imaging in many marine environments. Different multiple removal methods were applied to a data set typical of the Norwegian Sea. Comparison of the results indicated that Surface Related Multiple Elimination (SRME) in combination with a differential move-out method gave the best final data. Overview of methods Slowly decaying water layer multiples arising from a strong impedance contrast at the sea floor severely degrade the quality of the seismogram. In addition peg
