    Inside the Workflow - Unsupervised Machine Learning for Seismic Interpretation

    “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 compare results with seismic sections, wells, and regional context to confirm what is real. > PCA and SOM make complex attribute sets easier to explore. By reducing dozens of attributes into clearer clusters, they help interpreters see channel shapes and reservoir variability that might otherwise be overlooked.

    What It Takes to Trust AI in Real-World Seismic Applications

    “Deep learning is ubiquitous in data processing. The question is whether we have the courage to change the way we work.” Yangkang Chen discusses how deep learning has moved from experimentation to production in seismic processing and earthquake monitoring. Drawing on a decade-long effort to build an operational AI-driven monitoring system, he explains why tasks like first-arrival picking, velocity analysis, denoising, and reconstruction are especially well suited for deep learning. Yangkang emphasizes that success depends not just on algorithms, but on benchmarks, stability, teamwork, and trust. He also highlights how open and reproducible research lowers barriers for adoption and helps geophysicists apply AI confidently in real workflows. KEY TAKEAWAYS > Deep learning excels at repetitive, label-intensive seismic tasks that are slow and inconsistent using traditional methods. > Operational AI requires trust, built through benchmarks, validation, and a clear understanding of model behavior. > Open and reproducible workflows accelerate adoption, collaboration, and innovation across the geophysics community.

    Two Trillion-Dollar Ideas Leon Thomsen Tried to Give Away

    “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 demanding as pure research. Looking ahead, Leon shares his perspective on the future of applied geophysics, including opportunities in fracking optimization, carbon sequestration monitoring, and subsurface hydrogen exploration, and offers encouragement to young scientists preparing to navigate the energy transition. KEY TAKEAWAYS > Energy is a technology business: Long-term success depends on leadership that understands and trusts science, not just short-term metrics. > Applied science is real science: Solving practical problems can be as intellectually challenging and rewarding as purely theoretical work. > The next frontier is subsurface innovation: Geophysics will play a critical role in fracking efficiency, CO₂ monitoring, and hydrogen exploration during the energy transition.
