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…
Is it possible to differentiate between meandering and braided river deposits using gamma-ray logs?
For most people working in subsurface teams, discussions related to the interpretation of depositional facies on the basis of well logs are part of the daily routine. The more geologists…
Pumped geothermal power projects – a global overview
Pumped-well geothermal projects utilise the moderate temperature range of geothermal fluids between 100-190 C. Below this temperature, geothermal fluids are generally used for direct heating and above this the fluids…
Seismic acquisitions focus on mature hydrocarbon provinces
As always, conferences are great places to gauge the state of play of the industry. Yesterday, I talked to several people with good insight into the seismic acquisition business at…
Swimming in subsurface data – on YouTube
A new way of providing subsurface intelligence is the use of videos compiled by geoscientists. Sharing content in this way can be rewarding but daunting at the same time. That…
