Global investment firm Carlyle and the European Bank for Reconstruction and Development (EBRD) have agreed to sell Black Sea Oil & Gas (BSOG), Romania's largest offshore natural gas producer, to Mazarine Energy.

The transaction covers Black Sea Oil & Gas and BSOG Holding Activity, with completion subject to customary regulatory approvals.

Following the acquisition, BSOG will remain the operator of the Midia Gas Development (MGD) project in the Romanian Black Sea, which has supplied approximately 12% of the country's domestic gas demand since production began in June 2022.

Under Carlyle's ownership, BSOG led investments of more than $400 million in MGD on behalf of itself and its joint venture partners, developing the first offshore hydrocarbon production hub in the Romanian Black Sea in more than 30 years.
