Greek officials have announced the completion of all administrative procedures for the entry of US energy company Chevron into Block 10 in the Gulf of Kyparissia, off western Peloponnese.

The announcement was made by Environment and Energy Minister Stavros Papastavrou and the CEO of the Hellenic Hydrocarbons and Energy Resources Management Company (EDEYEP), Aristofanis Stefatos, on Monday, confirming that the regulatory process for the company’s participation has now been fully finalized.

A Chevron delegation arrived in Athens on Monday for the agreement’s completion.

Block 10, located in the southern Ionian Sea off the Gulf of Kyparissia, was previously held by Helleniq Energy, which has transferred a 70% stake to Chevron following a joint request for participation in the concession.

Papastavrou said that, following the US energy major’s request to join hydrocarbon exploration activities, “the procedures have been completed,” marking Chevron’s expansion into a fifth offshore block in Greece. Chevron and Helleniq Energy have already signed agreements for four other offshore areas south of Crete and the Peloponnese.
