Recent advances in AVO technology: Will 3-term projections change how you interpret seismic data?
With Dennis Cooke
“In this talk, I make the argument that a very recent Geophysics paper on AVO can have a disruptive impact on how we interpret seismic data. Despite decades of solid advances in AVO technology, there are still some ‘warts’ in the way most of us implement and use AVO. The paper by Ball et al in the October 2018 issue of Geophysics resolves most if not all of those warts. That paper is titled “Three-term amplitude variation with offset projections” and it was awarded one of the 2018 Best Paper awards in the SEG journal “Geophysics”.
There are 3 main sections in this talk. They are: 1) I briefly show examples and summarize the conclusions of the Ball et al paper (without using equations!), 2) make the case that seismic interpreters should use conventional seismic reflectivity volumes only for mapping structure, but should switch to relative impedance volumes when interpreting geology and 3) generation and use of Ball et al’s relative impedance volumes early in an interpretation project lowers project time and cost and increases reliability.”
