OMV Petrom, the largest energy producer in Southeastern Europe, and NewMed Energy Balkan, a subsidiary of NewMed Energy, have announced the signing of a rig contract for the drilling of two offshore exploration wells in the Black Sea, offshore Bulgaria.

This milestone marks a significant step forward in the two companies’ strategic efforts to unlock new energy resources in the region.

The contract was awarded to Noble Corporation, a globally recognized offshore drilling contractor. The selected drillship, Globetrotter I, is a state-of-the-art ultra-deepwater drillship, designed for efficient offshore drilling operations.

'We are excited to move forward with this important phase of our exploration program in Bulgaria,' said Cristian Hubati, member of OMV Petrom Executive Board, responsible for Exploration and Production. 'This contract underscores our commitment to investing in the region’s energy potential and to working closely with local authorities and stakeholders to ensure safe, efficient, and environmentally responsible operations.'

Yossi Abu, CEO of NewMed Energy: 'We are excited about the opportunities NewMed has in Bulgaria alongside our partners and remain committed to advancing drilling operations in the license we hold together with OMV Petrom. The agreement announced today brings us one step closer to unlocking the potential we see in this license.'

The two wells will be drilled on the Han-Asparuh Block.

The drilling campaign is expected to start in the fourth quarter of this year and last approximately four months. The value of the rig contract is approximately USD 80 million.

The integrated drilling services will be provided by Halliburton and the well testing services will be provided by SLB.

Total drilling budget expected at approximately EUR 170 million.

This initiative aligns with Bulgaria’s broader energy diversification goals and has the potential to contribute significantly to regional energy security.

Han Asparuh 

Han Asparuh is an exploration block located in the western Black Sea in Bulgaria, south of the Neptun Deep block in Romania and has an area of 13,712 km² with water depths slightly below 2,000 m. Exploration activities started in 2012 and included geological and geophysical surveys and the drilling of three exploration wells. An extensive 3D seismic campaign was finalized in May 2020 to identify potential drilling targets.  

OMV Petrom in the Black Sea 

OMV Petrom has over 40 years of experience in oil and gas production in the Black Sea. In the Romanian sector, it operates several blocks, producing oil and gas in the shallow waters. In deepwater, OMV Petrom, in partnership with Romgaz, is developing the Neptun Deep project, with estimated volumes of 100 billion cubic meters of gas. First gas production from Neptun Deep is expected in 2027. More details about Neptun Deep here.
