"We (geophysicists) need to look where the markets are rather than expect people to come to us. We have skills, and it's just about finding where we can apply these in the future." Dr. Tim Dean discusses his Honorary Lecture, "Seismic Acquisition and the Energy Transition." In this episode, we talk about: > The evolving applications of seismic acquisition beyond oil and gas > The importance of minerals for the energy transition and the role of seismic in their exploration > Innovations in seismic technology that reduce costs and expand capabilities > Why geophysics is data science - and other ways geophysicists are missing out > The potential of passive seismic techniques in large-scale mineral exploration > The future of seismic monitoring and its role in the subsurface changes > Addressing the decline in geophysics education and the need for broader application awareness > Tim's interest in collecting physical nodes The need for the world to transition away from fossil fuel to renewable energy sources is well established. The seismic exploration industry has long been focused on fossil fuel exploration, so it makes sense that this transition will also impact the industry. However, the movement away from fossil fuels does open up new prospects for the seismic method's application in areas as diverse as geothermal energy and mineral exploration. This episode (and Tim's Honorary Lecture) examines these new applications and discusses the opportunities that are developing for the method's application and their likely impact on future developments. In this conversation with host Andrew Geary, Tim emphasizes the unparalleled imaging capabilities of seismic methods and their critical role in identifying deeper mineral deposits essential for the energy transition. Tim also discusses the challenges and opportunities in applying seismic methods to hard rock environments, the economic differences between the oil and gas and minerals industries, and the importance of evolving geophysical education to meet future demands. He advocates for geophysicists to proactively engage with other industries to showcase the value of their expertise and technologies.

"With ​every ​new ​acquisition, ​spend ​2% ​of ​your ​budget ​to ​do ​research ​to ​understand the ​noise ​and ​signal ​drivers ​in ​your ​area. ​It ​might ​help ​any ​future ​neighboring ​acquisition, ​or ​it ​might ​just ​help ​the ​field ​in ​general, ​​which ​you ​and ​your ​career ​will ​benefit ​from." Dr. Christof Stork discusses his Distinguished Lecture, "How Does the Thin Near Surface of the Earth Produce up to 100 Times More Noise on Land Seismic Data than on Marine Data?". OVERVIEW > The significance of addressing noise in near-surface land seismic data > The interplay of theoretical and practical approaches in seismic noise reduction > The importance of coherent noise removal before statistical noise removal > The limitations and future potential of FWI in land seismic > The role of research and development in improving land seismic data quality > The impact of corporate and economic structures on seismic research investment Along with host Andrew Geary, Christof delves into the intricate world of land seismic noise. Noise is a significant challenge in land seismic data that has long been overlooked. Christof focuses on the complexities of land seismic noise and innovative methods to address it. Christof's journey into addressing land seismic noise began with his fascination for land data and its significant yet under-researched impact on seismic imaging. Despite the advancements in marine processing and pre-stack depth migration, land seismic methods have yet to see comparable progress. He emphasizes the need for more attention and funding in this area, highlighting how crucial it is for improving seismic data quality. Christof also illuminates the concept of "poor coupling," a term that describes the disconnect between surface geophones and the wave field at greater depths. He argues that understanding the physics behind poor coupling can lead to better signal extraction and improved seismic data quality. One key takeaway from Christof's discussion is the importance of combining theoretical and practical approaches to tackle land seismic noise. He explains that while traditional methods rely heavily on statistical noise removal, this is limited in effectiveness. Instead, Christof advocates for a focus on coherent noise removal, which can significantly enhance the effectiveness of statistical methods and reduce the need for excessive data collection. Christof's passion for land seismic research is evident as he calls for more investment in R&D from both the industry and academic communities. He stresses the potential benefits of dedicating a small percentage of acquisition budgets to research and creative experimentation, which could lead to significant advancements in seismic imaging. Listeners will better understand why land seismic noise remains a complex problem and the potential pathways to progress.

"I've learned much more from my mistakes than I ever learned from my successes, because it was my mistakes that helped me to have successes." Meet the man behind the mission to diversify the energy sector. Dr. Isaac Crumbly shares the journey of the Cooperative Developmental Energy Program (CDEP) at Fort Valley State University, a program designed to pave the way for African American students into the energy industry. Dr. Crumbly has been pivotal in diversifying the energy industry's workforce since 1983. Dr. Crumbly's innovative approach recognized the value of internships and strategic partnerships to introduce African American students to the energy industry. At a time when energy companies in the Deep South rarely recruited African American college students for internships, Dr. Crumbly took matters into his own hands, reaching out to the industry and advocating for his students. One of his most inspiring creations is the dual degree program in geosciences, which was born out of necessity when Fort Valley State University couldn't offer geology or geophysics degrees. Dr. Crumbly's solution was to partner with universities in energy-centric regions, like the University of Oklahoma, to create a program where students could earn degrees critical to the energy industry. The impact of Dr. Crumbly's work is undeniable.

"With the magnetic method, you can say with some certainty that it will locate more than 90% of the existing wells. The grand challenge for locating abandoned wells are these wells where the casing has been pulled." Richard Hammack discusses the December special section in The Leading Edge - orphaned and abandoned wells. When we think about the environmental challenges we face, orphaned and abandoned wells might not be the first thing that comes to mind. However, as this episode reveals, the issue is far more widespread and impactful than many realize. Richard expertly navigates us through the subtle yet critical distinctions between orphaned and abandoned wells, unraveling the complexities of these seemingly dormant structures that dot landscapes worldwide. The episode offers a fascinating exploration of innovative detection methods, from airborne magnetic sensors to the precision of drone technology, revealing how over 90% of steel-cased wells can be located.

Biondo Biondi, the Director of the Stanford Earth imaging Project (SEP), joins Seismic Soundoff to discuss SEP's 50-year history and future outlook. Biondo reflects on SEP's founding during the 1970s oil crisis and today as it tackles modern energy challenges. Biondo discusses how improving seismic imaging can support the future of carbon capture and geothermal energy and help build resilient cities. Biondo uses an article in The Leading Edge from 1987 on the then-called Stanford Exploration Project to offer insights into what we still know and don't know about geophysical data. He also shares why he believes so many SEP alums have been guests on this podcast! The Stanford Earth imaging Project is an industry-funded academic consortium within the Geophysics Department at Stanford University. SEP research has contributed greatly to improving the theory and practice of constructing 3-D and 4-D images of the earth from seismic echo soundings. The consortium was started in the 1970s by Jon Claerbout and is currently co-directed with Biondo Biondi. SEP pioneered innovations in migration imaging, velocity estimation, dip moveout and slant stack. SEP has recently been involved in 3-D seismic applications such as velocity estimation, wavefield-continuation prestack migration, multidimensional image estimation, and 4-D (time-lapse) reservoir monitoring. 📋 Episode Chapters (01:48) The Stanford Earth imaging Project celebrates its 50th anniversary (10:48) Areas the Stanford Earth imaging Project will impact over the next decade (12:49) The impact of Jon Claerbout's credo on the history and future of the SEP (13:46) Using fiber optic cables to monitor CCS projects and other uses (17:03) Biondo's challenge to the listeners 💬Guest Bio Biondo Biondi is the Chair of the Geophysics Department at Stanford University and Director of the Stanford Earth imaging Project. He and his students devise new algorithms to improve active and passive seismic data imaging. Because the datasets are enormous, and wavefield propagation needs to be accurately modeled to achieve high-resolution imaging, they need to harness the power of the latest computational hardware to test their methods on field data. Therefore, mapping imaging algorithms into high-performance architecture is essential to their research. The amount and quality of information they can extract from seismic data are directly linked to the temporal and spatial sampling of the sources and the receivers. In the past several years, they have been working on methods to process data recorded by using fiber cables as seismic sensors. Fiber-optic seismic recording promises to enable cost-effective continuous seismic monitoring at a large scale. A particularly exciting possibility is leveraging preexisting telecommunication infrastructure to continuously record seismic data with dense arrays in urban environments. In 2016, they pioneered that idea by recording data under the Stanford campus. Since then, they have recorded data in San Jose and on a 48-km array under Stanford and neighboring cities. ✍️ Episode References Visit https://seg.org/podcasts/episode-208-pioneering-seismic-imaging-for-energy-and-sustainability/ for the complete interview transcript and all the links referenced in the show.
