This process was developed in former times to provide higher data quality for migration algorithms and to cover areas with acquisition gaps.In addition to the exposed, for this data, the 5d interpolation algorithm compensates the effect of the fold ś decrease due to acquisition ś design in sections of the cube with less prospective interest.This paper shows the improvement obtained on the PSTM seismic image and its consequence on the seismic attributes generated after sub-surface interpolation.
