Wind and solar energy – temporarily stored in a salt cavern
One of the major challenges for the energy transition is the storage of excess energy that can be used at times when the wind does not blow or the sun…

A dissolvable tool
Andrew Garioch from Well-SENSE talks us through the use of fibre-optic technology for well intervention work
Shallow geothermal energy production may soon be more important than deep geothermal energy production in the Netherlands
It is a development that is not often talked about or highlighted in the media, but data on subsurface energy production using water as a carrier clearly shows how important…
The race for pressure space
Another pressure plot without values on the Y-axis! That’s what I thought when watching Eirik Jenssen’s presentation at the Dig X Conference in Oslo yesterday. Eirik works as a Reservoir…
CNOOC makes largest offshore hydrocarbon discovery in special rock formation. What is that about?
Last week, I was struck by a headline published by media outlet OGV. It read: CNOOC makes world largest offshore hydrocarbons discovery in special rock formation. Reading through the article,…
How to explain the low energy output of one of the UK’s flagship geothermal projects?
In September last year, the UK Government announced a list of renewable energy projects that qualify for a minimum price guarantee for the energy delivered to the grid. Geothermal projects…
What is the longest well drilled along hole?
Based on a post on social media, in which we asked our followers to name the well with the highest step-out ratio – the ratio between horizontal distance and vertical…
Not as straight as we sometimes think
Of course, field observations have long shown that faults are not the perfectly straight lines we often see in schematic cross-sections. However, subsurface data do not always allow the detailed…
Oil – and increasingly gas – on steroids
“We went from two to nineteen mudlogging units recently”, said a representative from Geolog at the IPTC Conference in Saudi Arabia this week. “It is obvious that things are picking…
A tent and a rig
Looking out of the plane window when approaching Dammam, Saudi Arabia’s oil capital, the darkness of the desert is interrupted by star-shaped lights in places. I wondered what they were…
Monitoring a geothermal motor
Following the drilling of successful exploration wells into the Kenyan Rift Valley in the 1970’s, the flagship Olkaria geothermal field has seen a steady development to a capacity of around…
Oil in the Dammam field overburden – lateral migration or an imperfect seal?
Next week, I’ll be attending the IPTC Conference in Dammam, Saudi Arabia. It made me look at the local geology of the area, only then to realise that Dammam is…
