In a move reflecting a shift in energy strategy, Greece is returning to offshore exploration to strengthen its energy security and leverage its domestic resources.
A major milestone for Greece's energy sector was achieved at the Ministry of Environment and Energy, with the signing of the exploratory drilling contract for Block 2 in the Northwest Ionian Sea.
The contract was signed between the ExxonMobil – Energean – HELLENiQ Energy consortium and Stena Drilling, which will provide the drillship for the operation.
The scale of the opportunity is significant. Estimated potential reserves stand at approximately 270 billion cubic meters of natural gas. roughly 40 times Greece's annual consumption of 6–7 bcm. Drilling will reach a depth of 4,622 meters, at an initial cost of €60–70 million. Should the well prove successful, a further €5 billion in development investment would follow, with potential state revenues estimated at €10 billion over 20 years.
Drilling at the "Asopos" prospect is expected to commence in early 2027 marking Greece's first offshore exploratory drilling activity in nearly half a century. Operations are expected to last approximately 60 days.
The Minister of Environment and Energy, Stavros Papastavrou, emphasized that if significant natural gas reserves are confirmed, this could trigger a major boost in economic growth and enhance Greece’s geopolitical influence.
Energean CEO Mathios Rigas stated:
“This is a new and completely unexplored geological play. Current estimates point to 280 billion cubic meters of gas, compared to Greece’s annual consumption of 6–7 bcm, making the potential impact on energy security significant.”
He added:
“However, this is an exploration well, and the probability of success is 16%, which is typical in our industry. ExxonMobil’s participation reflects confidence in the data, while all risks are borne by the companies, not the Greek state or its citizens.”
U.S. Ambassador Kimberly Guilfoyle praised the collaboration, noting that Greece is emerging as a leading player in regional energy transition. Stena Drilling also expressed its pride in being part of the project.
The project carries significant economic weight, not just for the energy sector, but for Greece's broader growth trajectory and its standing as a regional energy hub. The Minister described it as a "realistic energy transition," built on domestic resources rather than imported dependency.
For Greece, the timing matters. A discovery of this scale could strengthen its position as an energy producer and a regional partner across Southeast Europe.
This also aligns with the role IN-VR has consistently supported over the years, advancing energy sector development and enhancing energy security across Greece and the Balkans. We are proud to be part of this journey.
