Deconvolving water-gun seismic data

Abstract

Presents a filtering technique for deconvolving water-gun seismic reflection data using a composite signal recorded by sonobuoy receivers. It is shown that deconvolving the water-gun seismic reflection data with the calculated composite signal significantly improves the stratigraphic resolution of the seismic data. Further, the deconvolved seismic reflection data, the best estimate of the acoustic impedance contrasts as a function of depth, are in good agreement with independently derived acoustic impedance contrasts from downhole logging data at Sites 752 and 754. -from Authors
