Seismic Soundoff

“We really need to be able to explain in clear language and with vivid examples just what geophysics can do here.”

Michael B. Helgerud and Manika Prasad approach CCUS monitoring from two useful angles: Mike as an operator and Manika as an academic. Using their The Leading Edge special section on geophysics for CCUS as a starting point, they examine what monitoring must prove to operators, regulators, and communities as projects scale.

Mike emphasizes containment, pressure, storage capacity, and fit-for-risk surveillance. Manika points to major gaps in shared calibration data, basin-wide stress models, and especially the willingness to share mistakes and lessons learned.

Together, they argue that better technology alone will not settle the challenge. Geophysicists must combine different measurements more effectively, plan for decades of stewardship, and understand that communities may experience storage risk very differently from the scientists and operators evaluating it.

QUESTIONS THIS CONVERSATION ANSWERS
> What must geophysics demonstrate for operators, regulators, and communities to trust CO2 storage?
> Why is sharing calibration data, mistakes, and lessons learned essential to scaling CCUS monitoring?
> How should monitoring change when CO2 storage must remain secure for decades rather than a single project phase?

Geoscience needs more people who can solve problems across energy, water, climate, critical minerals, and the subsurface, yet departments are losing students, funding, and in some cases the field experiences that help build strong geologists.

Esther Oyedele and Dolores van der Kolk discuss what they heard across IMAGE about that disconnect and why solving it will take more than recruitment. Students need to see a wider range of geoscience careers, universities need flexibility without weakening the fundamentals, and industry and professional societies need to help support the training, field work, and access that make those careers possible.

The workforce problem is visible. Many of the solutions are visible too. The question is whether the geoscience community is willing to support them.

“We always aim for 60 percent. The other 40 percent, we are ready to make mistakes, learn from those mistakes, and then move forward.”

A 600-meter carbonate platform forced Dr. Ahmad Riza Ghazali and his PETRONAS team to reconsider a basic assumption in their seismic workflow.

Acoustic FWI and reverse time migration could not adequately image the layers beneath it, while 3D distributed acoustic sensing revealed extensive P-to-S mode conversion at the carbonate boundary. That evidence led the team toward multiparameter elastic FWI. And images that Ahmad says helped support successful drilling.

His SEG Pacific South Honorary Lecture, Next Generation Seismic Imaging Elastic FWI and Wavefield Solutions for Seeing Through Complex Carbonates, turns that experience into a regional argument. As exploration moves toward deeper Miocene carbonates, better physics may expose plays conventional imaging misses. The remaining challenge is economic and organizational because elastic FWI costs substantially more, requires teams to learn together, and asks decision-makers to invest before the outcome is certain.

QUESTIONS THIS CONVERSATION ANSWERS
* What does mode conversion reveal that acoustic FWI misses beneath thick carbonates?
* How did 3D DAS change the team’s understanding of a failed imaging result?
* What gives decision-makers enough confidence to drill from an emerging workflow?

Julian Chenin calls IMAGE “Disneyland for geoscience,” and after walking the exhibition floor it is easy to understand what he means. But for ROGII, the real value is what happens when people stop at the booth, pull out a notebook, and start sketching an idea together. Julian describes it as innovation happening in real time, with people from different parts of the subsurface workflow suddenly in the same conversation.

Those conversations have mattered as ROGII has grown from a company focused mainly on geosteering into a much broader part of the subsurface workflow. This year Julian is hearing renewed interest in older assets, northern Brazil, Guyana, Africa, the Gulf of Mexico, and underdeveloped unconventional plays. His point is that exhibiting is not simply about showing what you already built. Sometimes the conversations on the floor help determine what you should build next.

Companies have spent years storing more and more data, but Amii Rozell and Hana Kabazi make an important distinction: saving the final answer is not the same as saving why you made the decision. Three years later, the interpretation may still be there while the lease problem, environmental concern, rejected idea, meeting discussion, or uncertainty behind it has disappeared. AI can help recover that context, but it can also sound very sure of itself when the record has holes.

That leads to one of the most useful AI conversations I heard at IMAGE. Amii says companies are doing plenty of explaining about what AI is, but not enough training on how employees should actually use it. Hana’s advice is essentially the same thing teachers have always asked for: prove it. Ask where the answer came from, ask what the model does not know, understand the difference between public tools and protected enterprise systems, and do your own research before turning an AI inference into an operational decision.
