April DGS Luncheon: Jim Fowler “Finding Signal in the Noise: Using Multiples and Mode Conversions to Improve AVO Inversion”
Wynkoop Thursday, April 9th
11:30-1:00
“Finding Signal in the Noise: Using Multiples and Mode Conversions to Improve AVO Inversion”
Jim Fowler, Senior Project Development Geophysicist, Qeye Labs
Seismic reservoir characterization in geologic settings with coals, anhydrites, and gas clouds is known to be challenging due to transmission effects and non-primary energy introduced by these strong velocity contrasts. The problem of these high-reflectivity events masking the amplitude response of underlying reservoirs is well known and understood to be difficult to overcome in AVO inversion workflows. In this study, we compare a standard AVO inversion workflow, which relies on convolutional modelling, to a new workflow that uses 1D tau-p domain wave equation as the forward modelling operator in an effort not only to more accurately model the Full Waveform input seismic data, but to use the short period multiples and mode conversions to improve AVO inversion results.
Speaker Bio
Jim Fowler has been a QI geophysicist for 25+ years, beginning with Jason Geosystems in 1998. Since then, his work has focused on seismic inversion, AVO studies, and all aspects of reservoir geophysics. Most recently, he spent 14 years in multiple European countries with Wintershall Dea, culminating as Geophysics Coordinator for Norwegian Exploration, thereby gaining currency in wider geophysical applications (acquisition, processing and interpretation). Currently, Jim is based in Houston as an independent reservoir geophysics consultant on long-term contract with Qeye Labs.
