Abstract
Summary
Would you throw away data just because it was not intentionally recorded?
This is often the case when dealing with continuous recording systems, where prior to processing the data is divided up into shot records which exclude the overlap from the next shot. The resulting decrease in record length can be detrimental to the imaging of deep targets. The goal of this paper is to demonstrate a method to recover signal present in the overlap zone. The proposed method is based on a robust-rank reduction 3D filter applied cable-by-cable across a range of shot points and channels. The results are encouraging and show that signal recovery is feasible even in this unusual blending scenario characterized by extreme amplitude differences between blended signals.
