Romania has narrowed first gas from the €4 billion Neptun Deep project to the first half of 2027, bringing an expected 8 bcm/year of Black Sea production closer to the regional market as Central and Southeast Europe seek alternatives to Russian supply.
Developers OMV Petrom and Romgaz said seven of the project’s ten development wells have been completed, while the offshore platform and main pipeline infrastructure are already installed.
Plateau production is targeted by the end of the third quarter of 2027 at around 140,000 barrels of oil equivalent per day, equivalent to roughly 8 bcm of gas annually.
Recoverable resources are estimated at about 100 bcm.
The tighter timetable matters beyond Romania.
At plateau, Neptun Deep could produce volumes comparable with a significant share of current Romanian consumption, potentially freeing additional gas for export into Hungary, Bulgaria, Moldova and other regional markets.
Romania is already becoming an important northbound gas transit market as supplies from Greece and Bulgaria move towards Central Europe.
New domestic production would strengthen that role and reduce reliance on imported gas.
The key commercial question will be how much of Neptun Deep is absorbed domestically and how much reaches neighbouring markets.
Pipeline capacity, storage and long-term sales contracts will determine that balance.
The project is now moving from development risk towards execution risk.
With most wells completed and major offshore infrastructure installed, the remaining challenge is delivering first gas on schedule and ramping output rapidly enough to influence regional supply by winter 2027-28.
