Seismic full waveform inversion algorithms and their numerical behaviour
Kristopher Innanen, University of Calgary
Seismic full waveform inversion (FWI) comprises the use of Newton methods to update subsurface geological property models, in which data are simulated with maximally complete (e.g., elastodynamic) modeling of seismic data. It currently represents the state of the art in geological image-forming, but many basic and applied research questions remain and are being addressed. At CREWES we have developed a set of time and frequency domain FWI codes in the MATLAB environment, for purposes of analysis of algorithms and small-scale field testing. This talk will give an overview of methods, results and conclusions our research group has produced using these codes.
