Seismic Soundoff

“The major pitfall of machine learning of any kind is to be overly confident in the results. We run the risk of garbage in gospel out.” This discussion offers a rare chance to go a little deeper into a Leading Edge article and hear directly from the authors about the thinking behind their workflow. Satinder Chopra and Kurt Marfurt walk through how unsupervised machine learning, careful attribute selection, and simple preprocessing steps can reveal subtle channel features in a deepwater New Zealand example. It feels less like a theory lesson and more like practical guidance on using machine learning as a helpful partner in everyday seismic interpretation. KEY TAKEAWAYS > Small workflow choices have big impact. Clean input data, thoughtful attribute selection, and simple normalization steps often determine whether machine learning highlights geology or just amplifies noise. > The value is in the combination of tools and judgment. Unsupervised methods quickly expose patterns, but interpreters still need to com

“Oil company management has to understand that its business is essentially a technology business. It's not a marketing business.” In this episode of Seismic Soundoff, Andrew Geary speaks with Dr. Leon Thomsen about his memoir, “‘Surely You’re Joking, Mr. Thomsen!’: Adventures of a Petroleum Scientist,” and a career that helped redefine applied geophysics. Leon reflects on the experiences that shaped his scientific mindset, from early exposure to field crews, to formative lessons in geology at Caltech, to decades of research in academia and industry. He explains how curiosity-driven exploration led him to recognize the importance of seismic anisotropy and shear-wave technology, work that ultimately carried trillion-dollar implications for hydrocarbon exploration. The conversation also explores why transformative ideas often struggle inside large organizations, how a lack of technological literacy in management can lead to missed opportunities, and why applied science can be every bit as creative and demandi

“Distributed chemical sensing really is the next frontier in fiber-optic monitoring. It adds a new dimension by directly connecting chemical changes in the environment to signals we can read.” Distributed chemical sensing (DCS) is an emerging technology that utilizes fiber optics to measure chemical changes over long distances in real-time. Authors Christian Totland, Thomas Dylan Mikesell, and Peter James Thomas join host Andrew Geary to discuss their new paper, "Distributed chemical sensing: An unexplored frontier in urban, industrial, and environmental monitoring." Unlike traditional point sensors, which only capture data at one location, DCS has the potential to provide continuous chemical information with both high spatial and temporal resolution. This innovation could transform how we monitor pipelines, groundwater, and industrial sites, while also opening new opportunities for collaboration between geophysics, chemistry, and material science. KEY TAKEAWAYS > DCS can detect leaks, contamination, and ch
