Chevron’s planned gas exploration south of Crete brings American commercial interests into one of the Eastern Mediterranean’s most contentious maritime disputes. For Greece, the investment offers an opportunity to strengthen its position against competing Turkish and Libyan claims. Yet a major U.S. energy company’s presence does not guarantee Washington’s intervention if Turkey or Libya tries to obstruct exploration.
In February 2026, Chevron and HelleniQ Energy signed agreements for four offshore exploration blocks, including two south of Crete, with Chevron holding a 70 percent operating interest. Beyond potential gas discoveries, the project allows Greece to pursue exploration in waters affected by competing maritime claims.
A major U.S. energy company’s presence does not guarantee Washington’s intervention if Turkey or Libya tries to obstruct exploration.
On October 20, Libya’s Benghazi-based House of Representatives approved the Tripoli government’s 2019 maritime memorandum with Turkey, reversing its earlier opposition and reflecting Ankara’s growing influence in eastern Libya. Greece maintains that the agreement disregards the maritime rights of Crete and other Greek islands.
Seismic surveys are expected to begin in December, with operations south of Crete expected in early 2027. Turkey has already challenged the Greek exploration agreements. Libya has also objected to activities in maritime areas it claims and warned that continued exploration could affect negotiations with Athens.
The involvement of an American company introduces a new consideration. Turkey can dispute Greece’s maritime claims, but obstructing an American-operated project could create problems with Washington. Libya also needs foreign investment to develop its energy sector. Both have reasons to avoid a confrontation that could discourage international companies from operating in the region.
Yet the investment’s strategic value depends on how these governments assess American intentions. Ankara may believe that Washington will avoid a serious dispute with Turkey over offshore exploration.
Chevron’s activities in Libya further complicate the situation. In January 2026, it signed a memorandum of understanding with Libya’s National Oil Corporation and later secured an exploration block in the Sirte Basin. The company therefore has commercial interests on both sides of the dispute, and it wants access to resources and stable operating conditions, not a confrontation between governments. Athens should not confuse the company’s willingness to invest in Greece with support for Greek foreign policy.
For Greece, the immediate priority should be to prepare for the surveys without assuming that American involvement will prevent interference. The Greek government should consult Washington on possible responses to intimidation at sea and maintain communication with both eastern and western Libyan authorities. Athens must also continue discussions on maritime delimitation, even with Libyan officials who support the Turkish agreement. Refusing engagement would leave Ankara with greater influence over Libya’s position.
Athens should also recognize the limits of its regional partnerships. While Egypt rejects the Turkish-Libyan memorandum, it continues to improve relations with Ankara, with interests including border security, political stability, and economic cooperation. These priorities do not always coincide with Greece’s maritime concerns. For that reason, Athens needs to strengthen its own diplomatic channels rather than depend on other governments to contain Turkish influence.
Chevron gives Greece an additional argument in Washington. However, it cannot replace Greek diplomacy. The project’s value will depend on whether Athens can secure support for peaceful exploration while keeping channels open with Libya. It should also avoid presenting every objection to the surveys as a reason for confrontation. Diplomatic protests and physical interference are different challenges and require different responses.
American officials need to talk openly with both Ankara and Tripoli, making it clear that any threats or attempts to block vessels will draw a diplomatic response.
This distinction matters for Washington as well. While American companies operate across the Eastern Mediterranean, the United States benefits from regional investment and greater energy diversification, but its relationships with Greece, Turkey, and Libya do not always serve the same objectives.
Washington faces a critical choice as exploration draws closer to the most sensitive waters. It’s not enough to remain on the sidelines—American officials need to talk openly with both Ankara and Tripoli, making it clear that any threats or attempts to block vessels will draw a diplomatic response. That could mean public statements or direct engagement with the governments involved. The point is to protect U.S. business interests, without getting dragged into a military commitment or taking sides on Greece’s claims.
Soon, the surveys themselves will put this to the test. If American investment truly matters in the region, the reaction of Turkey and others will take this into account as operations move forward. Washington cannot expect U.S. companies to fly the flag and spread influence if it looks the other way when trouble starts. If the goal is stability and open seas, the United States needs to show it is willing to push back—at least diplomatically—when disputes start turning into real-world standoffs.
