Abstract

This paper presents the application of source signature deconvolution for improving the resolution of VSP data and removing shot-to-shot variations. The method has low complexity and requires minimal changes to current deployment and acquisition practices, and is applicable for land and marine surveys. We have applied the algorithm to vertical incidence offshore data. The method successfully removes shot-to-shot variations, and compresses the wavelet to zero phase, improving the resolution of the data and uncovering events which were hidden by the long air gun signature. We suggest this method should be adopted as a routine processing step in all VSP surveys, although the technology will be of greatest benefit in time-lapse experiments.
