"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.

"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.

GUEST BIO

Christof Stork started as a theoretical academic with a PhD in geophysics from Caltech and a post-doc from Stanford 36 years ago. He performed early leading work in reflection tomography, PSDM, WEM, RTM, and FWI before they became mainstream technologies. Ten years ago, he decided to take on noisy land seismic data where more than theory is needed. Christof has been involved with four startup companies in his quest to avoid Houston and make theory commercially viable. He’s now on his fifth, last, and craziest startup company, a land seismic processing company so that he can get his hands on more land data.
