The end of Eavor?

A feat of engineering. That’s how the Eavor loops in Geretsried could be described. But that’s about it. When it comes to contributing to the energy transition, and the advance of geothermal energy, I think Eavor has not achieved much.…

Recent study points at North Sea being the highest global emitter of methane from abandoned wells – but is that true?

In a study recently published in National Science Review (NSR), the North Sea appears to be the basin that is home to the largest emitters of methane from abandoned oil and gas wells. This has already raised eyebrows with journalists, and calls into…

Keeping geoscientists busy

Geoscientists can go too far in the relentless pursuit to de-risk all elements that could cause a CO2 store to leak. At least, that is my take based on listening to a presentation by a member of the Endurance Partnership…

Why data obtained by legacy gas wells are not always a good indicator for assessing geothermal potential

The Upper Permian Rotliegend sandstone in the Netherlands is a very well-explored reservoir. That is because a lot of gas fields are reservoired in this aeolian and fluvial succession that attains thicknesses up to 300 m in places. But the…

Has the Aarhus geothermal project become a little less geothermal than initially planned?

In a recent statement on LinkedIn, geothermal exploration and development company Innargi announced that its flagship project in Aarhus, Denmark, will be developed differently from what was originally foreseen. Where the idea was to build seven production facilities with associated…

Making small pools work

Despite there still being major uncertainties for operators on the UK Continental Shelf, as Niall McLean from Brodies Solicitors clearly explained in his talk about the Finch ruling, when talking to people during coffee breaks at the recent Devex Conference,…

“We’re in this weird time of pre-AI and post-AI”

A few months ago, I published some thoughts on how Norway has proven to be such a hotspot when it comes to new subsurface technology. Dan Austin, who has been in Norway for quite a few years, got in touch…

The presence of oil and gas at a geothermal conference

“I work on gas installations, but I have come to this conference to network, as so many people from the sector are here,” somebody tells me at the lunch table when I get into a conversation. Another company I speak…

Picking prospects: Exploring the Orchard Platform’s Haupt Dolomite play

The UK mid North Sea High (MNSH) can be considered as one of the least explored hydrocarbon provinces on the UK Continental Shelf. Early drilling campaigns targeted pre-Permian structures, with the Z2 Haupt Dolomite only regarded as a secondary reservoir…

Less oil, more water

It is something that I am not often exposed to, but that does not mean it is unimportant – produced water. The SPE Aberdeen section organized a panel discussion around the challenges of produced water yesterday, during which five experts…

Finding the right store for CO₂ can lead to very different outcomes

It happens quite regularly that people’s surname seem to be closely linked to the profession they operate in. This certainly applies to Alexander Bump from the University of Texas in Austin. Even when he wasn’t really advocating for storing CO2…
