Vol. 22

Issue 3

We want our magazine to be a place people go to inform themselves of what is happening in the subsurface energy industry. Or, what is not happening…. We talked extensively to Marit Brommer, the CEO of the International Geothermal Association. She thinks that playtime is over, and geothermal should now scale up globally in the way it is doing in China. Here, the government has put out a clear mandate to use geothermal for heating purposes in large cities. Why does it not happen in more places? Read the interview!

For our cover story, we spoke to two world-renowned experts in the field of Direct Hydrocarbon indicators; Henry Pettingill and Rocky Roden. We went back to the basics of Amplitude Versus Offset, and also discussed the most important pitfalls when using the technique that has enabled de-risking of many of the worlds high-impact exploration wells.

Sometimes one needs to look beyond traditional data portals to find a great geological source of information. It happened to the team at CASP, who found a continuously cored section covering a large part of the Triassic in the Southern North Sea. This core proved to be essential for a study on the storage potential of Triassic reservoirs, as well as the sealing properties. A unique dataset that has been a game-changer for creating a better framework.

Producing a source rock and storing it in the subsurface; it’s a relatively new concept that has not had a lot of press, but it offers an attractive model of storing carbon in the subsurface permanently. We talked to Tim Baars from ReCoal, a Switzerland-based company that aims to scale up this technology fast.

And as always, our contributors shine their light on a wide variety of topics, from basin modelling to oil in basement, you will find it in this extensive issue.
