Seismic Soundoff

"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. President Reagan and President Obama have honored CDEP, recognizing the program's contribution to STEM and the importance of expanding representation in the geosciences.

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.
