The global energy sector from a subsurface perspective

Geology & Geophysics

Going deeper for salt mining

Henk Kombrink
The Dutch subsurface is well known for its gas resources, hosting the world-famous Groningen field. What is less well known is that there is plen­ty of salt, too. These evaporites…

What do air hockey and induced seismicity have in common?

Molly Turko, Devon Energy
At first glance, air hockey – a fast-paced arcade game – and induced seismicity – earthquakes trig­gered by human activity – seem unrelated. Yet, both share a fascinating connection through…

The Grand Canyon of the Middle East

The outcrop photo shows what is commonly known as the Grand Canyon of the Middle East: Wadi Ghul and Wadi Nakr in the Jebel Shams Massif in northern Oman. From…

When your oil reservoir turns out to be a lithium deposit

István Nagy-Korodi, Consulting Geologist
As the global energy transition accelerates, the demand for critical raw materials (CRMs) is rising at an unprecedented pace. The list of elements essential for modern technol­ogies – from lithium…

Hydrocarbon and seal properties are key

Lukasz Krawczynski and Martin Neumaier
Most commonly, Petro­leum Systems Analysis (PSA) studies tend to focus on source rock distribution, its quality, and the ther­mal regime of the basin to then model migration pathways and the…

Dead oil traces in a lonely pebble bed

Henk Kombrink
Where most explora­tion activity on the UK Continental Shelf took place in the North Sea, and later along the Atlantic Margin west of the Shet­land Islands (WOS), it is good…

Porosity in compressional stress regimes

David Rajmon, Consulting Geologist
Porosity prediction sits at the heart of basin models and pros­pect evaluation. It underpins our understanding of reservoir quality, pore pressure, and thermal his­tory. Traditionally, porosity has been modelled as…

Sponge clasts in calciturbidites

Text: Henk Kombrink, Photography: Ali Jaffri, Applied Stratigraphix.
At the recent IMAGE Conference in Houston, somebody told me that the Permian Basin in Texas is not only famous for its hydrocarbon resources, but also because the uplifted areas…

Pasties, piskies, pegmatites… and Pliny

Juan Cottier, MMbbls Subsurface Consulting
Britain has strong, quiet, an­cient communities on its fur­ther reaches: Norse Shetland, Gaelic and Doric Scotland, Wales, the Isle of Man, and Cornwall at the southwest tip. All connected by…

Decoding slip with tension gashes

Molly Turko, Devon Energy
Tenson gashes are fractures in rocks formed under ex­tensional stress, of­ten filled with minerals like quartz or calcite. These fea­tures are key kinematic indi­cators in structural geology, revealing fault slip…

“The day I cut an 88 ft core of top seal”

Henk Kombrink
“LinkedIn seems to be the place to brag about your career successes,” says Luke Johnson from TRACS International in this video. But sometimes, it is things that went wrong that…
