Μake us preferred on Google Chevron is preparing to begin seismic surveys in Greek waters before the end of 2026, as the U.S. energy major moves to identify potential hydrocarbon targets in its offshore concessions.
Environment and Energy Minister Stavros Papastavrou announced the start of the work during a visit to the United States, where he was part of Greece’s delegation to the 81st High-Level Week of the U.N. General Assembly.
Papastavrou met with Beatrice Bienvenu, Chevron’s country head for Greece, who confirmed the timeline for surveys in the Ionian Sea and in areas south of the Peloponnese and Crete.
According to information, the surveys are expected to take place in November and December, when a specialized seismic vessel contracted by Chevron is due to arrive to acquire geophysical data.
Chevron holds four offshore blocks awarded by the Greek state: A2, South of Peloponnese, South of Crete I and South of Crete II. It recently also entered Block 10. The vessel is expected to survey the first four.
Work will most likely begin in Block A2 before moving to South of Peloponnese, with the two blocks off Crete to be surveyed in the first half of 2027. The data will then be evaluated, and new 3D seismic surveys are planned for later in 2027.
Block 10 is considered the most mature of Chevron’s concessions. Chevron has requested an 18-month extension of the block’s second exploration phase. The block would be ready for drilling if, during that period, its 2D and 3D geophysical data point to a target with a realistic chance of a commercial discovery.
