New mineral discovery in the Norwegian Sea
Grøntua is the name of the new sulphide deposit that was found during a trip under the auspices of the Center for Deep Sea Research at the University of Bergen…

The birth of a new play
This is a story of how subsurface data was used in the way it should be – to incrementally gain a better understanding of how a petroleum system works. And…
A 1 % error margin is not acceptable anymore
It is something that many geoscientists may not think about daily, but there is a whole community in the upstream oil and gas sector that is working to make sure…
Exploration geology – science or art?
During my career in the oil industry, exploration geology has changed enormously. Not long after I joined Shell in February 1979, my son, who was play school age, asked me…
Never say no
“I was born disciplined”, says Aluka at the start of the interview. “With my parents both being academics, it was no surprise that I wanted to learn”, she continues, “but…
The time of deep resistivity
Times are gone that deep resistivity tools are only being used for geo-steering. The inverted data help build geomodels, help estimate net pay thickness away from well data and see…
The geoscience of decommissioning
“ Let’s not try to sugarcoat it, it wasn’t always easy”, she continues. “The pandemic unfolded, and taking care of homeschooling, a full-time job and completing the university modules on…
Time-lapse gravity
Monitoring strategies for offshore Carbon Capture and Storage (CCS) cannot simply replicate those used in the oil and gas industry, which often rely on 4D seismic methods. Regulations mandate monitoring…
Geothermal energy from buried basement rocks
Closed-loop shallow geothermal boreholes drilled up to a depth of around 200 m are quite common in Estonia. But recently, the Geological Survey decided to embark on a project to…
With ‘real-time’ reservoir management now within reach, energy companies are seeing they simply have no choice but to adapt to the growing technology landscape
Basemap: Location of the UKCS 3D Seismic Merge – Central North Sea (polygon) with an associated High Definition Frequency Decomposition RGB colour blend along time slice 1960 ms. Why the…
The cream of the outcrop
This panorama shows an Upper Miocene succession, la Rambla de Lanujar, in the Betic Cordillera, featuring in one of our field trips to Tabernas, Almería, Spain. Apart from being a…
How the winner of a technology competition made room for the losers to take over the market
Sweden comes third in the list of countries using geothermal energy. But it is not deep geothermal energy, it is shallow geothermal – mostly sourced through closed loop systems of…
