Oz Yilmaz discusses his latest book, "Land Seismic Case Studies for Near-Surface Modeling and Subsurface Imaging." Written for practicing geophysicists, this book is the culmination of land seismic data acquisition and processing projects conducted by Oz over the last two decades. Containing nearly 800 figures from worldwide 2D and 3D case studies, it is a comprehensive guide to understanding the acquisition, processing, and analyzing of seismic data. In this episode, Oz shares why marine versus land seismic makes an important difference, why the image-based workflow described in the book matters to geophysicists, the criteria for a migration algorithm to qualify as a depth migration algorithm, one of the most likely applications of artificial intelligence for seismic data analysis, and more.

Josef Paffenholz discusses the next trillion-dollar business and how SEG's SEAM project could play an essential role in its creation. The SEG Advanced Modeling (SEAM) Corporation initiative is a collaborative industrial research effort that has created and continues to create large-scale, leading-edge geophysical numerical simulations. The initiative has advanced “the science of geophysics through SEAM’s open collaborative and cooperative research model involving industry, government, and academia.” In this exciting conversation, Josef highlights why the oil and gas sector represents the best source to tackle industrial-scale carbon storage, why he believes it's dangerous to link carbon storage to the oil price, and how advanced simulations like SEAM could ignite this trillion-dollar business. Josef Paffenholz is a retired research geophysicist and currently works as a consultant for SEAM to prepare a possible carbon sequestration project.

Historian Brian Frehner discusses the energy transition from coal to oil and the historical importance of J. Clarence Karcher. June 2021 marks the 100th anniversary of field tests confirming that J. Clarence Karcher's seismic reflection technique could detect and map structures capable of trapping oil. In this future-focused conversation, Brian discusses why Karcher left the oil business after his major breakthrough, the impact business had on the development of the oil industry, the creation of geophysics as a discipline, and the lessons learned for future energy transitions. 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 transitions. Visit https://seg.org/podcast for the complete show notes. BIOGRAPHY Brian Frehner is an Associate Professor of History at the College of Arts and Sciences at the University of Missouri-Kansas City. Brian writes and teaches about the history of oil, energy, the environment, and the American West. He is currently at work on a monograph that recounts the history of the science and technology that make up the field of “exploration geophysics” during the first half of the twentieth century. He is also co-editing a volume that examines the role of technology in facilitating humans’ adaptations to their environments. This project is funded by the National Science Foundation and is tentatively titled “Great Plains: An Environmental History.” He is also the author of Finding Oil: The Nature of Petroleum Geology, 1859-1920.
