Vertical seismic profiling enable one to analyse and understand geological origin of the wave field generated. The biggest advantage over surface seismic methods is that we have both transmitted and reflected fields available for an analysis; hence we can say that by recording VSP data we are conduct in situ rock-sample measurements. The two fields can then be used to infer rock properties. VSP data also helps us process and/or understand the problems we encounter when processing surface seismic data. We thus use VSP data for most of surface seismic related investigations to utilise the benefits of having full wave field available for the analysis.
Therefore it is of great importance to pursue continuing development of VSP data processing and analysis algorithms for the benefit of oil and gas exploration. The main areas of interest are 2D/3D imaging using monotypic and converted waves, anisotropic imaging, estimation of Q factor from VSP data and developing alternative approaches to Q-compensation and polarisation analysis for investigation of seismic anisotropy.
