When the lithium cycle bites back
Commodity cycles rarely announce their turning points. They emerge quietly, through inventory data, project pipelines, and subtle shifts in physical markets – long before consensus catches up. The lithium price…

Geomechanical models – not a luxury but a risk management tool
After over a hundred years of research and development, geomechanics modeling is not just a nice-to-have accessory in a drilling campaign, but it is one of the main pillars to…
Love and sex and oil and passion
We also never forget those true loves. We carry them for life. My first time and first love was Beatrice. I consider myself very lucky. I was young, and she…
Looking for a low-risk infill well? You might want to consider areas of weak 4D response
When porosities and fluid contrasts are modest, the acoustic impedance (AI) changes associated with water sweeping oil can be small, even at relatively shallow depths. That is the case in…
How structural setting and hydrocarbon phase are closely related
The Papuan Basin is located across a tectonically active area and is dominated by a gas-prone Jurassic petroleum system with a whole-of-system Gas-Liquid Ratio of 30,000 scf/bbl. The complex geology,…
Going deeper for salt mining
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?
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
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
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
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
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…
