Did you know that rocks have memory?
The seismic signature of a sedimentary rock is strongly influenced by the geological history of the rock, e.g., the depositional environment, whether it has experienced tectonic burial and uplift, etc.…

Half full or half empty
“Oil major ExxonMobil bets that through technological advances, shale producers can manage to double crude output from their existing wells.” That was one of the headlines from an article published…
Exploring CO2 storage efficiency: striving for clarity
Prior to building a full 3D model of a carbon store, the mass of CO2 that can be stored in a reservoir can be calculated by multiplying the pore volume by the…
Embracing change
“My parents approached my upbringing in different ways”, says Hayet when we met up on Teams to do the first part of this interview. “My father, an accountant, is curious…
Rapid and long-lasting sealing of bedrock using concretion-forming resin
Wells and underground excavations typically require effective permanent sealing when they have fulfilled their intended functions. Abandonment of hydrocarbon production or CO₂ injection wells or sealing of underground waste repositories are…
A passion for the product
“My best tip for salespeople new to the job is to establish long-term relationships with clients. Let them know you will go the extra mile and show them a passion…
FWI Imaging under complex geological anomalies
Map of Offshore Liberia with project location in orange. Figure 2: a) Tomography and 15Hz DM FWI (refraction) velocity model; b) Additional higher frequency DM FWI run up to 40Hz…
A new hydrogen play
Exploration for geologically occurring hydrogen is taking off worldwide. In May, FDE announced a serendipitous discovery of hydrogen whilst drilling for coalbed methane in the Lorraine region in France. In…
ISA: No quick decisions despite deadline breach
The Metals Company (TMC) is eager to begin production. They might be the first company in the world to start deep sea mining in the Clarion-Clipperton Zone (CCZ), located in…
If you are not using ensemble modeling, you are most likely leaving money on the table
Most reservoir development or management decisions require a three-dimensional numerical representation of the reservoir. Intuitively, that digital representation consists of a single model to which all subsurface disciplines contribute to…
Understanding geothermal energy
The energy contained in a geothermal fluid is defined by its enthalpy, generally given in kilojoules per kilogram (kJ/kg). For a liquid, the enthalpy is primarily determined by its temperature.…
From Statfjord Øst to Suriname – this week’s subsurface news and observations
Longboat – Acquiring interest in Statfjord Øst A small surprise this week was to see Longboat Energy acquiring a 4.8% share from INPEX in one of the most mature fields…
