oa Comparison of Deconvolution Methods for Removing Signature Changes from VSP Data after Stacking

A signature change was observed on Z component over the depth interval of 1905.0 to 2011.0 m. The acquired data was investigated for any inconsistency during the acquisition. No comment was reported by the field engineer to mention about change in pressure or depth of the airgun, but hydrophone data showed breaks in signature which could be due to change in either depth or pressure of the airgun.
