Offshore Oil & Gas Discovery in Poland’s Permian Basin Margin in the Baltic Sea is Very Significant: Could Be Biggest Find in Europe in a Decade

   A major Polish oil & gas discovery was just announced by Central European Petroleum (CEP) a few kilometers offshore, far northwest Poland, near the German border. It has been touted as one of Europe’s biggest oil and gas discoveries of the past decade. The find is along the margin of Poland’s Permian Basin. The reservoir rocks appear to be a zone in the prolific Zechstein Dolomite, specifically the Ca2 main dolomite, with significant potential in the Rotleigand Sandstone below the dolomite.









     I wrote about oil & gas in Poland in September 2024, and this new discovery adds a new source to that. Poland, along with several European countries, imports the vast majority of their oil & gas, so new domestic discoveries could benefit the country. I wrote then:

Currently, Poland imports up to 95% of the oil it consumes. Thus, finding domestic oil is very significant. Poland has worked hard to wean itself off of Russian oil and gas. Poland consumes about 580,000 barrels of oil daily, of which it imports approximately 540,000 barrels. In 2023, about 45% of Poland’s oil was imported from Saudi Arabia. For a country very dependent on imports, even small oil finds are significant. Russia was, of course, opposed to the development of Polish shale gas when it was being pursued, since it would compete with Russian gas. Poland’s electricity grid is powered mainly by carbon-intensive, air pollution-intensive lignite coal. A bigger domestic natural gas industry could alleviate that pollution and CO2 emissions by burning natural gas instead. However, at low production rates, it would require lots of wells and increase land use, landowner, and environmental issues as well.”

     The new discovery is part of CEP’s Wolin East Concession. The (WE1) well, some 6 kilometers from the port city of Świnoujście in Poland's northwest, may contain 22 million tons of recoverable crude oil and condensate, along with 5 billion cubic meters of commercial-grade natural gas. According to EuroNews:

The broader concession area, spanning 593 square kilometres, is estimated to contain over 33 million tonnes of oil and condensate, as well as 27 billion cubic metres of gas.”

That would more than double Poland’s current estimated oil reserves, which stood at around 20.2 million tonnes in 2023, according to Polish public broadcaster TVP.”

If confirmed, the discovery would rank as Poland’s largest conventional hydrocarbon deposit and among the biggest in Europe in the last 10 years, according to the Polish Press Agency.”

     CEP’s CEO Rolf G. Skaar noted:

Wolin East is more than just a promising deposit — it is a joint opportunity to unlock the full geological and energy potential of the Baltic Sea.”

The Polish Exclusive Economic Zone in the Baltic Sea, of which Wolin East is a part, is considered to be underexplored, so more new discoveries are possible. Wolin East could become the largest oil and associated gas deposit ever discovered in Poland. That would be a victory for a country that needs domestic energy and has suffered from failures and geological issues in its once-touted shale gas reserves in the 2010s.

     According to the press release:

Tests confirmed a 62-meter hydrocarbon column and excellent reservoir properties for oil and gas production in the Main Dolomite geological formation. “

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.”  

     The WE1 well was drilled in February 2025. The well then underwent logging, core analysis, and downhole testing. The well was drilled with a jack-up rig to a depth of 2,715 meters in 9.5-meter deep waters. The well encountered a 62m hydrocarbon column in the Main Dolomite. Original estimates were for a higher gas content and a lower oil content. In either case, Poland needs both gas and oil.
