CEP Makes ‘Significant’ Oil Discovery Offshore Poland
July 22, 2025

Canadian exploration and production company Central European Petroleum (CEP) has made a significant oil discovery in its fully owned and operated Wolin East 1 (WE1) well, located in the Baltic Sea, offshore Poland.
The WE1 well was drilled using Noble Corporation’s Noble Resolve jack-up rig in waters 9.5 meters deep and reached a vertical depth of 2715 meters.
Tests confirmed a 62-meter hydrocarbon column and excellent reservoir properties for oil and gas production in the Main Dolomite geological formation, according to the company.
The Wolin East oil discovery is estimated to contain mean recoverable oil, sales gas and natural gas liquids totalling 200 million barrels of oil equivalent (mmboe).
There is also significant further low-risk exploration, appraisal and secondary recovery potential within the license in the Main Dolomite as well as in the deeper Rotliegend formation.
With these opportunities included, the Wolin license in total is estimated to contain more than 400 mmboe of recoverable hydrocarbon resources, which constitutes the largest conventional hydrocarbon field yet discovered in Poland, and one of the largest conventional oil discoveries in Europe in the past decade, CEP claims.
“This is a historic moment for both Central European Petroleum and Poland’s energy sector. We view this discovery as a foundation for long-term, responsible development of Poland’s offshore resources. Wolin East is more than just a promising field – it represents a shared opportunity to unlock the full geological and energy potential of the Baltic Sea,” said Rolf G. Skaar, CEO of CEP.
“The discovery of the Wolin East hydrocarbon deposit – although it still requires the preparation, submission, and approval of the deposit’s geological documentation – may prove to be one of the breakthrough moments in the history of hydrocarbon exploration in Poland, especially with regard to areas that have so far remained insufficiently explored, such as Poland’s Exclusive Economic Zone in the Baltic Sea.
“If this discovery is ultimately confirmed, the Wolin East deposit could become the largest oil and associated natural gas field discovered in Poland to date. The future development of this site may significantly contribute to strengthening Poland’s energy security and reducing its dependence on external hydrocarbon suppliers, provided that all necessary formal requirements enabling its exploitation are met in advance,” added Krzysztof Galos, Undersecretary of State and Chief Geologist.
