How to identify fluid migration with 1D models and temperature data
One revealing experience occurred while I was working in a basin offshore Thailand. I only had temperature data from several wells. Once a 1D model was built for each of…

How AI-based image analysis of cuttings enables better reservoir definition
With the advance of new AI-based technologies, drill cutting data can now be quickly and consistently analyzed and interpreted to better characterize the subsurface. Working together with Bapco Upstream, we…
The Caribbean
The presence of oil in the Caribbean has long been known, and has successfully been explored for across the region – with producing fields in Cuba, Barbados, and the Caribbean…
Looking into the 2025 subsurface crystal ball
But first, what was the talk of the town in 2024? Namibia stole many of the headlines, as it continues to do today and will probably continue to be doing…
Eyes wide open at the right time
“I took the most jagged path into the oil business, as you can imagine,” says Henry S. Pettingill. “There was nothing for me to identify myself with the oil industry,…
Getting drill-ready for the energy transition
Frank van Bergen “If you don’t include the subsurface in the journey towards reducing CO2 emissions, it will be impossible to reach net zero”, says Frank van Bergen. Frank heads…
The evolution of managed pressure drilling
Nick Ward “Managed pressure drilling (MPD) has been around for a long time”, says Nick Ward when we meet in his office in Tullos, Aberdeen. Nick oversees the MPD business…
Jevons paradox
The environmental ideology driving the statement, “the sooner hydrocarbons or fossil fuels are gone, the better for the world”, is misguided and misses the fact that to create a positive…
Data fabric architecture – the solution to explore better?
Geologists like visuals. That is why Puneet Saraswat and his colleagues from Querent AI are a step ahead already, because they create visuals, out of large collections of reports. They…
A seismic facies library
Seismic facies classification can be a tedious process, especially in an exploration context where large areas need to be assessed. In order to speed up that process, using a library…
Death by 0.9
During an evening lecture organized by the Geoscience Energy Society of Great Britain (GESGB) in Aberdeen the other day, a discussion unfolded about how to risk play elements in a…
Less is more – uncertainty in rock properties
My last article opened a topic of uncertainty in basin models. Discussion following its publication brought up an interesting research paper describing how increasing model complexity increases uncertainty in its…
