196: The sound of seismic

Philip Ringrose discusses his upcoming Distinguished Instructor Short Course, "Storage of Carbon Dioxide in Saline Aquifers – Building confidence by forecasting and monitoring."

Interest in carbon capture and storage (CCS) is growing rapidly as a crucial part of global efforts to reduce greenhouse gas emissions into the atmosphere.

In this conversation with host Andrew Geary, Philip reviews the science and technology underpinning CO2 storage in deep saline aquifer formations using insights from several industrial-scale projects. Philip also addresses what's needed to achieve climate-significant scales of CCS deployment. Although technically achievable, the current socio-economic framing often makes storage project execution difficult in practice. By building technical confidence in project execution, we may be able to "turn the dial" and realize the gigatonne levels of storage needed over the coming decades.

Philip is an excellent guide for understanding CO2 storage, its possibilities and limits, and how to use your geophysical skills to support CO2 projects. You should listen to this episode if you are interested in this topic.

201: Carbon storage data management done right

Steven Lynch discusses his article in The Leading Edge, "High visual resolution interpretation: The case for virtual seismic reality." 

Steve lays out the case for why the seismic you have is better than you think. He argues that the industry needs to undergo a complete change of mindset regarding visualization. Steve explains a natural seismic display, the third form of resolution that's often ignored, and the unsung technological hero of the 20th century. 

Steve hopes to convince you that there's a tremendous amount that you're not seeing. And that most of the information acquired in seismic has yet to be observed or interpreted. This episode will give you much to think about - and maybe help you unlock new oil in old places.

BIOGRAPHY
Dr. Steven Lynch is the Chief Geoscientist for "The Visual Wavefield Project." He received his B.Sc. in Biophysics from the University of Guelph in 1975 and his M.Sc. in Geophysics from the University of British Columbia in 1977. Following a 26-year academic absence, Steve returned to University in 2003 to study seismic visualization and received his Ph.D. from the University of Calgary in 2008.

Steve has a wide range of experience in both geophysical research and software development. Early in his career, he managed seismic processing centers and developed techniques for such subjects as refraction statics, depth migration, ray trace structural modeling, and stratigraphic modeling.

In the early 2000s, realizing that our ability to perceive seismic needs to keep pace with our ability to acquire and process it, Steve returned to his biophysical roots. He began to study visualization as a science. His research led him to pioneer the field of Virtual Seismic Reality. He now splits his time between developing software for it and teaching courses about it.

202: The next revolution in seismic interpretation

Chao Wang and Stephen Graf discuss the October special section in The Leading Edge on deep exploration.

In the 1920s, the first oil discovery in Seminole, Oklahoma, was made at a depth of approximately 4,000 feet. In 1949, the average depth was 3,600 feet. By 2008, it was 6,000 feet. Currently, the world's deepest oil well in Russia extends 49,000 feet into the earth's surface.

Deep exploration below existing production, complex overburden, or at the limits of geophysical resolution is critical for existing and emerging ventures. To meet these challenges, researchers and geoscientists are actively working to acquire better data and develop innovative methods to improve imaging. And in this episode, guest editors Chao Wang and Stephen Graf highlight the recent advances that improve success and extend capability in challenging deep environments.

Chao and Stephen explain how and why the various geological settings impact deep exploration. They outline if land or marine exploration is easier and which has the greater potential. They explore the role of machine learning and AI for deep exploration and what other technological developments warrant attention.

Chao and Stephen also share one misconception the public often has about deep exploration and one future development they are most excited about. They also discuss what surprised them across the six papers in this special section and how their different perspectives impact how they see the future of this topic.

206: Arthur Cheng on His SEG Journey from Student to President

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.

(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.

223: Innovating for a Sustainable Future with Geophysics

"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.

224: The Physics Behind Land Seismic Noise (Christof Stork)

"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.

No matter where you are on your geophysics journey, this episode is a must-listen. This conversation is challenging and insightful and may just save geophysics.
