BSOG is Romania’s largest offshore natural gas producer. As operator, it led the investment of more than $400 million in the Midia Gas Development (MGD) project, the first offshore hydrocarbon production hub in the Romanian Black Sea in more than 30 years. The project includes the offshore Ana platform, a 126-kilometre subsea pipeline and the onshore gas treatment plant at Vadu. Since coming onstream in June 2022, MGD has become a significant contributor to Romania’s energy supply. The project produces more than 100 million standard cubic feet of gas per day, accounting for 11.8% of Romania’s total natural gas production during the first half of 2026, according to ANRE’s monthly reports.
BSOG will remain the operator of the MGD project, ensuring continuity as the business enters its next phase of development. For Mazarine Energy, the acquisition builds on an existing operating presence in Romania.
Edward van Kersbergen, CEO of Mazarine Energy, said: “Romania has been a core part of Mazarine Energy’s business since 2017, and we are proud to build on that presence with BSOG. MGD is a major achievement for the country’s energy security, and we are committed to carrying forward what the BSOG team has accomplished and to supporting Romania’s energy supply for years to come. We thank Carlyle and the EBRD for their trust and look forward to working with the BSOG team, our partners and the Romanian authorities.”
