Chevron Secures Four Greek Offshore Exploration Leases in Strategic Mediterranean Push

Event summary

  • Chevron and HELLENiQ ENERGY signed lease agreements for four offshore exploration blocks in Greece, with Chevron holding a 70% operating interest.
  • The blocks are located south of Crete (South Crete 1, South Crete 2) and within the Peloponnese (South of Peloponnese, Block A2).
  • The consortium was selected following an international tender launched by the Greek government in 2025.
  • Phase one of the leases involves 2D and 3D seismic exploration work programs to assess hydrocarbon potential.
  • The agreements are subject to ratification by the Greek Parliament.

The big picture

Chevron's acquisition of four offshore exploration leases in Greece marks a significant expansion in the Mediterranean region, where it already operates gas fields in Israel and Cyprus. This move aligns with Chevron's strategy to strengthen its global energy portfolio and unlock new supplies in frontier regions. The deal underscores the company's focus on exploration and development in politically stable yet under-explored areas, potentially positioning it for long-term growth in the Eastern Mediterranean energy sector.
