A puncture in a geothermal seal
More than fifteen years ago, Delft University of Technology (TU Delft) was one of the first institutions in the Netherlands to come up with the idea to warm their premises…

“In 10 years, nobody would risk installing a subsea well without fibre optic sensing”
It is corrosion resistant, has a long lifetime, no electronics are required downhole, and the “cable” is only a quarter of a millimeter thick. Fibre optic sensing technology has a…
Hydrocarbon shows don’t necessarily mean a significant discovery
“MCF Energy Announces Significant Gas Discovery in Austria“, is the headline of a press release issued a few days ago by Canadian player MCF Energy. That sounds like exciting news…
Deciphering the wealth of data that come from fibre optic sensing
It is corrosion resistant, has a long lifetime, no electronics are required downhole, and the “cable” is only a quarter of a millimeter thick. Fibre optic sensing technology has a…
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…
