Disposal of probes in Prušánky
In March 2025, the abandonment of three production wells in the Prušánky area was successfully completed - specifically wells Prušánky 4b, 6 and 8. Together, these probes opened and produced the Labe horizon in the Middle Baden on the subsiding crust of the Schrattenberg fault system.
The liquidation took place on the following dates:
- Prušánky 6: 6-13 March 2025
- Prušánky 4b: 14-18 March 2025
- Prušánky 8: 19-25 March 2025
Mining history
- Prušánky 4b was an exploration well that discovered a natural gas field in July 2006. The well produced both gas (51.13 million m³ in total) and oil (4,795.58 m³), with an average daily oil production of 28 m³ in 2013.
- Prusanky 8, a well drilled in 2009, verified the northern extension of the field. Production continued until April 2019, when the horizon was watered. A total of 62.68 m³ of gas and 11,407 m³ of gasoline were produced.
- The Pruzhany 6 well, drilled in 2013, was designed to help complete the oil zone but only captured the gas portion of the field. Between 2014 and 2019, 13.86 million m³ of gas and 41 m³ of gasoline were produced.
After evaluating the electrofracture measurements, no further saturation was detected in the overburden horizons, and therefore it was decided to dispose of the probes after production was completed. This brings to an end almost 20 years of production in the Prušánek area, which has yielded significant energy resources in the form of natural gas, oil and gasoline.

An IT guy who goes to the vineyard to clear his head
The road above Moravský Žižkov comes to an end, and from there on, the only way forward is a path winding through the rows of vines. It is here that Milan Svoboda ‘clears his head’ after work. During the day, he maintains servers and manages cloud systems and their security; in the afternoons, he picks up his secateurs and tends to the vineyard.
The new look of the Úprkov site
The refurbishment of the MND site and building on Úprkova Street is gradually transforming the working environment to better meet the current needs of both the company and its staff. This is not merely a technical upgrade – the project specifically combines functionality, aesthetics and the community aspect of the space. The transformation of the site is not taking place in a single phase. The refurbishment of the interior spaces has been underway since 2024 and also includes technical aspects such as the modernisation of the heating system. The modifications to the outdoor area are based on an architectural study prepared by Jung architekti at the end of 2025.
Poddvorov 27 – A reclamation project with a future
Perhaps no other MND site better illustrates the successful reclamation of land following the end of mining operations. The site of the former Poddvorov 27 borehole now serves as an example of how an area left behind by mining operations can be given a new purpose and actively utilised once more – in the form of a modern agrovoltaic concept.
