Bacterial life is everywhere in the subsurface

Not-so-hot volcanic rocks in Saudi Arabia

This in what a team of researchers concluded in a paper published in the journal Geothermics this year. It must have been a bit of a surprise to find very…

Preventing scaling in geothermal production wells

The Munich area in Germany is lucky when it comes to its geo­thermal potential. There is a good Upper Jurassic car­bonate reservoir at the right depth, and the water com­position…

Too fast, too soon

In Geothermal energy production, it is all about the tem­perature of the produced water, brine or steam. A drop in temperature has a direct effect on the amount of energy…

Pushing the limits of tracer technology

Faster and faster

Drilling faster is a big driver for technological develop­ment in every aspect of the subsurface industry, and the shallow geothermal sector is no exception. “We can significantly increase the drilling…

Drilling into new frontiers – drilling into magma

No, it is not entirely new. Drilling straight into magma has happened be­fore. But in Iceland, the Krafla Magma Testbed (KMT) con­sortium is now going to research it more rigorously…

Finding a hotspot in Alaska

Domestic gas production in Alaska’s Cook Inlet is declining rapidly, and for that reason, there is now an incentive to further increase the share of renewable energy. One candidate to…

Monetizing the geothermal resource

“The Client we work with in Dakota at the moment applied fans to cool the produced fluids from their assets before it was piped away. Now, we ex­tract the heat…
