DEN 14 | The potential of hydrocarbons in Greece and the "Vertical Corridor" transformation

Greece has taken a decisive step into large-scale offshore hydrocarbon exploration with a landmark agreement between Chevron and HELLENiQ ENERGY, unlocking key offshore areas south of Crete and the Peloponnese. The deal marks a transition from state-managed concessions to privately operated exploration, positioning Greece as a potential natural gas producer and strategic energy hub in the Eastern Mediterranean. Backed by Chevron’s capital and technical expertise, the initiative aligns with Europe’s urgent need to diversify away from Russian gas while strengthening Greece’s geopolitical and economic role in the region.

Chevron assumes a 70% operating stake, bringing deepwater expertise and financing, while HELLENiQ ENERGY retains 30% participation without early-stage capital burden, significantly de-risking Greece’s exploration efforts.

The new concession nearly doubles Greece’s offshore exploration area to ~94,000 km², covering four key blocks (South Crete 1 & 2, South Peloponnese, Block A2), with significant untapped gas potential.

Potential reserves (e.g., up to 280 bcm south of Crete) could cover decades of domestic demand
The Greek state is expected to capture ~40% of project value
Could help fill Europe’s post-Russian gas supply gap

A successful discovery would transform Greece from a transit country (LNG imports) into a gas-producing and exporting hub, supporting infrastructure like the Vertical Corridor and enhancing regional energy security.
