Abstract

The inadequate coverage of seismic data in congested/ logistically constrained areas often result in data gaps/low foldage due to missing offsets (traces) . This affects the data processing and noise elimination becomes challenging due to introduction of footprints as well as aliasing of the noise band resulting in poor imaging through PSTM. The offset regularization through prestack interpolation as a precursor to pre-stack migration helps us to improve seismic image. In this paper, the impact of Prestack interpolation is analyzed and used to interpolate the missing traces for regularize the data gap within a gather. The interpolation appears to be a viable solution pertaining to foldage enhancement and adequate noise elimination before imaging.
