#13: Chris Liner - Elements of 3D Seismology

Paolo Dell'Aversana highlights his article in The Leading Edge, discussing a dual-sensory approach to understanding seismic. In a first for this podcast, host Andrew Geary and Paolo discuss music's role in interpreting seismic. Based on concepts well-established in cognitive sciences, Paolo introduces the idea of expanded imaging in geophysics, using a dual-sensory (audiovisual) perception of a data set. In this episode, Paolo explains the basic principles of multimodal seismic data analysis using augmented imaging theory. He then provides examples and applications on real data at varying spatial scales, from individual seismic traces to entire seismic sections. Paolo shares the advantages and limitations of converting seismic data into an auditory format and outlines how geophysicists can start with this approach today. This episode unlocks secret information hiding in your seismic data waiting to be discovered. Listen to the full archive at https://seg.org/podcast. CELEBRATING 200 EPISODES!

Fabien Allo highlights his award-winning article, "Characterization of a carbonate geothermal reservoir using rock-physics-guided deep neural networks." In this episode with host Andrew Geary, Fabien shares the potential of deep neural networks (DNNs) in integrating seismic data for reservoir characterization. He explains why DNNs have yet to be widely utilized in the energy industry and why utilizing a training set was key to this study. Fabien also details why they did not include any original wells in the final training set and the advantages of neural networks over seismic inversion. He closes with how this method of training neural networks on synthetic data might be useful beyond the application to a geothermal study.

Lia Martinez shares the critical skills necessary to network successfully. In this conversation with host Andrew Geary, Lia offers tips and best practices to fully utilize networking to further your career and technical skills. She explains why seven follow-ups (or touches) is the magic number, the importance of establishing credibility early, and how to use note-taking to your advantage. She outlines the unique ways that both introverts and extroverts struggle with networking (and how to address them). Lia also explores why no one can tell if you have confidence (or not) and why approaching each person as an individual treasure chest can unlock career-defining connections.

Anja Klotzsche discusses her Near-Surface Global Lecture, "Unlocking the potential of GPR for subsurface characterization by using full-waveform inversion." The heterogeneous near-surface consists of the complex interactions between rock, soil, water, air, and living organisms, which determine the availability of life-sustaining resources such as water. This environment has been increasingly exploited for human needs, such as water supply, to store our waste and food production. To assess the environmental risk associated with such exploitation and exploration, the near-surface must be investigated and characterized with high-resolution methods to enhance our understanding of hydrological and biogeochemical processes. In this conversation with host Andrew Geary, Anja describes the recent developments in FWI that have impacted how to apply GPR. She outlines a few of her favorite GPR applications, the impact of AI on GPR, and the role GPR and FWI can have in improving management decisions. Anja also shares the lightbulb moment when she realized her method was special. And why she changed her mind about hydrogeophysics and EM methods. This episode will challenge you to consider GPR in a new way and, in so doing, put FWI in a new perspective as well. Listen to the full archive at https://seg.org/podcast.
