95% of seismic data was unused – for the wrong reasons
“My first start-up failed”, said Bill Shea at the EAGE Annual in Vienna recently. “But, maybe it was meant to be, because the second time it went much better and…

The basics of submersible pumps in geothermal projects
Pumped-well geothermal projects utilize “binary” power plant technology which consists of Organic Rankine Cycle (ORC) heat exchangers. The geothermal fluid is pumped from the wells as a single phase liquid…
Fast and slow catastrophes trapping slope and basin floor plays
Fast and slow catastrophes trapping slope and basin floor plays How slumping, sliding and folding of passive margin stratigraphy creates the elements for successful exploration while the latest seismic imaging…
Companies feel pressure to accelerate frontier exploration
“I might as well go gardening if it was not my role to speed up the process of discovering reserves through frontier exploration”, said Neil Hodgson from Searcher. One of…
An investment banker who solved a geophysical problem
Shell is a large company, and with that comes the existence of siloes across the organisation. Management in Shell recognised that as a problem, and therefore it created spin-off company…
From oil and gas to geothermal
Now known as S3 Smart Seismic Solutions, I met with Jean-Baptiste Chalvidan and Patrick Robert at the EAGE Annual in Vienna last week. “Compared to the years with CGG, where…
The drilling hazard that has become a prospective target
This year’s gas demand surge and associated price hike have led many companies to re-initiate exploration for gas. On that basis, shallow gas accumulations have re-appeared on the global exploration…
Spinning the CCS project wheels – it’s time to change gear!
As I write, CO2 is being injected from the Nini platform in the Danish North Sea as part of Project Greensand, the world’s first cross-border offshore CO2 storage project facilitated…
What a meeting at a conference can do
“As many people from my generation, I started my career with Saga Petroleum”, says Tore Karlsson. Having graduated as a geophysicist from the University of Bergen, at Saga he was…
Dropping nodes from a supply vessel
“While the node market has evolved in the sense that individual nodes have become smaller and therefore lighter to handle”, a completely new way of operating these devices has not…
Your ChatGPT-powered personal subsurface document assistant
During meetings, we often encounter detailed and specific questions, such as whether a particular well had shows in the Jurassic, why a licence was relinquished, or if there are any…
Machine learning validation – An often understated requirement in geophysics
Deep learning is a subset of machine learning, which entails a neural network with three or more layers. It is thanks to deep learning that applications from fault picking to…
