Developments are forthcoming in Greece’s offshore hydrocarbons sector after an extension granted to ExxonMobil for exploration of a block west of the large island of Crete expired without the multinational carrying out field operations.
The 12-month extension, granted last year until early April 2026 at ExxonMobil’s request, had been intended to provide additional time to assess the sea area’s geological prospects for hydrocarbon exploitation. The concession now appears set to revert to the Greek state after failing to attract sufficient interest for costly three-dimensional seismic surveys.
The Greek side is now expected to consider relaunching the concession through a new international tender, either in its current form or divided into smaller blocks. The leadership of relevant agency overseeing such contracts, the Hellenic Hydrocarbons and Energy Resources Management Co., has recently signaled plans for a fresh licensing round for seismic exploration across Greek maritime zones.
Officials hope renewed momentum in the country’s energy sector, fueled by planned drilling activity in the Ionian Sea, could draw additional international and mid-sized energy companies into the market, either independently or through partnerships with domestic firms.
Over the past year, Greece has accelerated efforts to position itself as a regional energy hub, advancing offshore exploration projects south and west of Crete while expanding strategic energy partnerships in the eastern Mediterranean.
Interest in hydrocarbon production has also intensified amid persistent geopolitical tensions and energy security concerns linked to instability in the Middle East.
