Episode 155: Removing the starting model for FWI

Arnab Dhara discusses his paper, "Physics-guided deep autoencoder to overcome the need for a starting model in full-waveform inversion," in the June issue of The Leading Edge. Arnab proposes employing deep learning as a regularization in full-waveform inversion. He explains why physics-based solutions with machine learning are challenging to develop, how he made it possible to train the network without known answers, and why he tested his approach with the Marmousi and SEAM models. Arnab also shares why this research took over 20 years to build on the initial idea and how he used full-waveform inversion without a starting model. This is a cutting-edge conversation that may represent the future of FWI.

115: How full-waveform inversion counteracts complex overburdens

Denes Vigh discusses the current developments and future growth areas for full-waveform inversion. In this informative conversation, Denes shares why it's necessary for full-waveform inversion (FWI) to utilize the full acquired wavefield, how ocean-bottom node surveys have impacted FWI, the next frontier for FWI, and his favorite feature of utilizing FWI in his work.

Episode 53: The pros and cons of full-waveform inversion

In this episode, host Andrew Geary speaks with John Brittan, contributor to March's The Leading Edge. March's special section returns to a common and major topic for TLE - full-waveform inversion. John highlights the advantages and disadvantages of several FWI approaches, discusses the possibilities and limitations of the technique, and explores the common themes across the seven papers. Episode 53 proudly sponsored by ION Geophysical.
