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…
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…
Nature’s microplastics
Palynologists are palaeontologists who specialise in microfossils composed of acid-resistant carbon-hydrogen-oxygen biopolymer. In other words, their fossils are nature’s microplastics. Resistant to almost anything diagenesis can throw at them, fossil…
The next step in a digital journey
Sometimes one hears people from operators moan about service company folk trying to sell their products at conferences. Such remarks do not do justice to these companies, as they are…
Swimming in subsurface data
In the UK, it is not that long ago that people had to go to the Department of Energy and Climate Change – which is now the North Sea Transition…
Maximising the potential of seismic expressions
Spectral decomposition methods are widely used to highlight geological features according to their frequency content. However, the frequencies characterising the targeted event might vary spatially, which complicates their extraction as…
Recent Advances in Climate Change Research: Part XVI – A Greenhouse Model for Stratospheric Cooling – 2
Increased concentrations of greenhouse gases are warming Earth’s surface and troposphere while cooling the mid to upper atmosphere. We introduce you to the 1D window-grey radiation model of the atmosphere,…
Recent Advances in Climate Change Research: Part XV – A Greenhouse Model for Stratospheric Cooling
Stratospheric cooling is considered to be one of the fingerprints of anthropogenic global warming. In this article, we present observations. It should be apparent from the title of this article…
The Sub-Salt Imaging Challenge
Throughout the world, sub-salt imaging remains a major issue. Service and oil companies are striving to meet this challenge. Sub-Salt Imaging Challenge
