Bentec 450 at the planned dress rehearsal
During the first quarter of 2025, the Bentec 450 is undergoing a five-year inspection. The rig had to interrupt its drilling campaign in Hungary, where it has been operating since last year, to carry out this important part of its regular maintenance. The inspection itself is mainly carried out in Lusatia and partly in Bad Bentheim and Hungary. Once completed, the BT450 is expected to be recommissioned and the project will resume during April.
During the five-year inspection of the main parts of the B450 kit, the following was carried out:

The Lužice complex following renovation
The second part of Karel Komárek’s two-day visit took him to the refurbished MND Drilling and Services site in Lužice. The project, involving an investment of 250 million crowns, not only saw the restoration of the site, which had been devastated by a tornado, but also its fundamental modernisation — from new operational areas and a central park to a comprehensive rainwater management system.
Košice as a springboard: MND sets its sights on further geothermal projects
The completion of the boreholes near Košice shows that deep geothermal energy can serve as a stable source of energy even in Central Europe. At the same time, however, it raises questions about where this type of project makes sense and how quickly it can be scaled up. Radovan Jedlička, Head of Business Development at MND Drilling & Services, discusses the potential, limitations and further opportunities.
