Estimation of attenuation from zero-offset VSP data: CO2CRC Otway Project case study, in Proceedings of the Annual Meeting of the Society of Exploration Geophysicists (SEG), Nov 4-9 2012. Las Vegas: SEG.

Understanding of seismic attenuation plays an important role in successful application of seismic reservoir characterisation techniques based on amplitude analysis. Zero-offset vertical seismic profiling (VSP) is one of the principal tools which can be used to study seismic attenuation. A comprehensive set of zero-offset VSPs and wireline log data was acquired as a part of CO2CRC Otway project. In this study we estimate apparent attenuation from these VSP data and quantify contribution of intrinsic and scattering components of attenuation using both mathematical modeling and generalized O’Doherty-Anstey theory. Having significant redundancy in the VSP data provides the means to evaluate reliability of our estimates.
