Noble Corporation, a globally recognized offshore drilling contractor, was awarded the contract. The chosen drillship, Globetrotter I, is an ultra-deepwater vessel designed for efficient offshore operations.

"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," said Cristian Hubati, Member of OMV Petrom Executive Board, responsible for Exploration and Production.  

The two wells will be drilled on the Han-Asparuh Block, with the drilling campaign expected to commence in Q4 2025 and last approximately four months. The rig contract is valued at approximately $80 million. Halliburton will provide integrated drilling services, and SLB will handle well testing services. The total drilling budget is projected to be around €170 million. 

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

The Han-Asparuh Block is an exploration block in the western Black Sea, south of Romania's Neptun Deep block. It covers an area of 13,712 square km with water depths slightly below 2,000 m.

Exploration activities began in 2012, including geological and geophysical surveys and the drilling of three exploration wells. A comprehensive 3D seismic campaign was completed in May 2020 to identify potential drilling targets.
