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.

Disposal of Ždánice probes: closing another chapter of mining
At the start of 2023, the decommissioning of three wells in the Ždánice area was successfully completed. This symbolically marked the end of a chapter in the long history of oil and gas extraction in this region. Each well had a different history and significance, but what they had in common was that they had fulfilled their purpose and, upon reaching the end of their life cycle, were professionally and safely secured in a permanent state.

Oil production at the Lanžhot field ends after 70 years
The site is awaiting reclamation and restoration to nature. After almost seven decades, mining at the Lanžhot deposit, the southernmost oil deposit in the Czech Republic, is coming to an end. In a remote forest area at the confluence of the Dyje and Kyjovka rivers, in a location that is located in a protected zone and whose administration is becoming increasingly demanding from a legislative point of view, only a few wells remain today. These will be gradually closed in the coming years and the entire area will be prepared for reclamation.
