Greece is set to re-enter offshore gas exploration, marking a significant shift in its energy strategy after nearly forty years. The government has signed a drilling contract with a consortium led by ExxonMobil, alongside partners Energean, Helleniq Energy, and Stena Drilling. This initiative aims to tap into the potential natural gas resources located in the Ionian Sea.
The focus of this exploration campaign will be on Block 2 within the northwestern Ionian basin, where geological surveys suggest the presence of substantial natural gas reserves. The first target identified for drilling is the Asopos 1 prospect, with operations anticipated to commence in early 2027.
Industry estimates indicate that the area may hold up to 270 billion cubic meters of natural gas, a volume significantly greater than Greece’s current annual consumption levels. The planned well is expected to reach depths exceeding 4,600 meters, necessitating an investment ranging from 60–70 million euros. While there are high expectations surrounding this project, stakeholders caution that the outcomes of such explorations remain uncertain.
If successful, large-scale development of the discovered resources could require additional investments estimated at up to 5 billion euros. Such developments could potentially yield considerable long-term revenues for the state. This project is seen as a pivotal opportunity for expanding Greece’s energy sector, though its commercial viability has yet to be established.
The initiative has been characterized by officials and international collaborators as part of broader efforts toward enhancing energy cooperation. This development not only aims to bolster Greece’s domestic energy supply security but also holds implications for overall regional energy stability.
