GEO EXPRO is run by a small but dedicated team of people who all work together from different parts of the world to produce six magazines per year, in combination with publishing the magazine’s content online and on social media.

Our mission is to report on developments in the energy sector from a subsurface perspective, taking the role of observer and commentator on projects both in the oil and gas and renewable space. As such, we acknowledge the major importance oil and gas still plays with regards to energy security, whilst keeping a close eye on new developments in low-carbon subsurface solutions at the same time.

The Core Team

Ingvild Ryggen Carstens

Managing Director

As a student, Ingvild helped distribute the first-ever issue of the magazine and has had a close relationship with GEO EXPRO ever since. In 2022, she took on the role of managing director in which she oversees the strategic partnerships and the day-to-day aspects that come with running a small business. Ingvild has a dual bachelor degree in Marketing and Management from the University of Wyoming, and an MSc in Strategic Management and Multicultural Branding from Universität Innsbruck. In addition to her work for GEO EXPRO, she also organizes a series of conferences for the Norwegian geoscience community, oversees several other geoscience websites and the publication of the GEO magazine in Norway. Ingvild is based in Norway.

Henk Kombrink

Editor in Chief

Following a career as a geologist mainly working on regional projects in the greater North Sea region, Henk has been working with Ingvild and her team since 2020, culminating in taking on the editor role for GEO EXPRO in 2022. Reporting from his home in Aberdeen, still regarded as Europe’s energy capital, he is always on the hunt for good stories that relate to energy and subsurface. Henk has an MSc in Physical Geography and a PhD in sedimentary geology from Utrecht University. In addition to taking care of the content of the magazine, Henk also runs North Sea Core, a community interest company that distributes cores from oil and gas wells in the UK North Sea, and he is the editor for the Netherlands Journal of Geosciences.

Pia Himberg

Sales Manager

Pia is based in Norway and brings years of sales and business development experience to the team. She is also well versed in the industry through her role as sales director for the Norwegian magazine GEO and website geo365.no, which she has been doing with Ingvild Ryggen Carstens for multiple years already. Pia has a degree in Globalization and Development, Organization and Leadership. With broad international experience, having lived in several countries around the world, it is not a surprise that Pia likes to travel. And when at home on the farm, which she runs with her husband, she takes care of the dogs and horses whilst also continuing to learn through obtaining a degree in law.
