ATHENS, Feb 16 (Reuters) - A consortium led by U.S. oil major Chevron signed exclusive lease agreements on Monday to look for natural gas off southern Greece, expanding the United States' presence in the eastern Mediterranean.
The deal doubles the amount of Greek maritime acreage available for exploration and is the second in months involving a U.S. energy major as the European Union seeks to phase out supplies from Russia and the U.S. seeks to replace them.
Exxon Mobil in November joined Energean and Helleniq to search for gas in another offshore block in Western Greece.
Monday's agreement allows Chevron to lead the search for gas in four deep-sea blocks, south of the Peloponnese peninsula and the island of Crete, stretching across 47,000 square kilometers (18,147 square miles). It follows Chevron and Hellenic Energy, Greece's biggest oil refiner, last year winning an international tender.
Greece, which has no gas production and relies on gas imports for power generation and domestic consumption, has revived its quest for gas exploration after a 2022 energy price shock driven by Russia's invasion of Ukraine.
The European Union is building up renewables capacity to cut greenhouse emissions, but has acknowledged the need for natural gas as a transition fuel to help stabilise the grid when intermittent wind and solar energy are not available.
The Greek parliament will need to approve the lease contracts before the Chevron-led consortium can start seismic research later this year. Greece has said the consortium has up to five years to locate potential recoverable deposits and any test drilling would not take place before 2030-2032.
Exxon Mobil and Helleniq also hold a licence to look for hydrocarbons in another two deep-sea blocks south of Crete and are evaluating seismic data before moving ahead with any exploratory drilling there.

Natural gas is a fossil fuel composed mainly of methane, used as an energy source for heating, cooking, and electricity generation.
An exploration agreement is a legal contract allowing a company to search for natural resources in a specified area.
Seismic research involves using sound waves to investigate the geological structure of the Earth, often to locate oil and gas reserves.
A consortium is a group of companies or organizations that collaborate for a specific project or purpose, sharing resources and expertise.
