Episode 138: The power and pitfalls of modern geostatistical models

Danilo Jotta Ariza Ferreira discusses modern geostatistic methodologies from the December 2021 special section on Latin America in The Leading Edge. Danilo shares how to avoid two common pitfalls in geostatistical modeling, why models are always wrong (but you should still use them), and highlights a few innovations in seismic-based geophysical solutions.

Episode 134: How to lower risk and operate more efficiently

Thomas Finkbeiner discusses geomechanics from the November 2021 special section in The Leading Edge. In this episode, Thomas highlights the link between geophysics and geomechanics in developing renewable and unconventional resources, explores case studies presented in the special section, shares the current state of research on induced seismicity during CO2 injection, and illustrates how geomechanics impacts the entire life cycle of a reservoir.

Episode 131: How to mine old theories for new insights

Vemund Thorkildsen discusses his paper, "Revisiting holistic migration," published in October's The Leading Edge. In this episode, Vemund discusses questioning the Nyquist-Shannon sampling theorem, mining gaps in past research, and examining the applicability of holistic migration to seismic field data. He also shares how he connected with Enders Robinson to serve as co-author on the paper.

Episode 129: Improving and reducing biases with a novel theory

Henning Hoeber discusses a new tool for rock physics in his recent paper published in September's The Leading Edge. In this episode, Henning explains the theory of omitted variable bias (OVB) and its connection to rock physics, why OVB hasn't appeared before in the geoscience literature, how OVB helps geophysicists understand biases in models, the real-world implications for improving a bias model, and how he will apply OVB to his future research.

Episode 127: Breakthroughs for surface-wave tomography for the near-surface

Myrto Papadopoulou and Farbod Khosro Anjom spotlight the recent advances in surface-wave tomography for near-surface applications from August's The Leading Edge. In this episode, Myrto and Farbod discuss why surface-wave tomography has not been applied regularly to near-surface applications, highlight more efficient models they developed, explain how automatic data screening allowed for their breakthroughs, and imagine what future advances in surface-wave tomography will occur.

Episode 122: The role of seismic interpreters in 2021

Jean-Paul van Gestel highlights the latest for seismic interpretation, the special section in July's The Leading Edge. In this episode, Jean-Paul discusses the interpreter's role in the workflow, why oil is first found in the mind of the geologist, how to take full advantage of the latest technology, and the best way to communicate to the decision-makers.

119: Why the energy transition from coal to oil matters today

Historian Brian Frehner discusses the energy transition from coal to oil and the historical importance of J. Clarence Karcher. The transition to oil may seem obvious now, but it was not inevitable. By studying the past energy transition from coal to oil, scientists and the public can better understand how transitions do and do not occur and better prepare for future energy transitions.

116: Addressing grand challenges with geophysics

David Lumley highlights two of SEG's Strategic Pillars and the geophysicists' role in supporting space exploration and the medical field. In this illuminating conversation, David outlines how geophysics supports the grand challenges of our world, how geophysics could quantitatively contribute to the medical field, how universities and companies could encourage greater collaboration, and a valuable tip to become a better innovator.

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.
