Greece is set to revitalize its offshore hydrocarbon exploration efforts, a sector that has seen little activity for nearly four decades. The Ministry of Environment and Energy is prioritizing the parliamentary approval of four offshore concession agreements involving Chevron, aiming for completion by January. This legislative move is critical for advancing the country’s hydrocarbons program and unlocking subsequent phases of exploration.
In parallel, Energean is pushing forward with its plans for exploratory drilling in the northwest Ionian Sea. The company anticipates that if regulatory procedures progress more swiftly than in previous cycles, it could commence drilling operations by late 2026. This would mark Greece’s first offshore exploratory well since the 1980s, signaling a significant shift in the nation’s energy landscape.
Under an optimistic scenario, Chevron could initiate seismic surveys south of Crete within a year, representing the first tangible field activities under the newly ratified concessions. These surveys are essential for informing future drilling decisions and will be conducted in areas designated as South of Crete I and South of Crete II. Energean has indicated readiness to drill in Q4 2026 or early 2027, contingent on timely regulatory approvals, including the Environmental Impact Study for Block 2.
The timeline for these activities is heavily dependent on the efficiency of state authorities in granting necessary clearances. Delays due to public objections or administrative hurdles could significantly hinder progress. For Chevron’s consortium, state officials expect seismic research vessels to gather data by late 2026, with further work planned in additional blocks following initial surveys.
Additionally, Helleniq Energy, Chevron’s Greek partner, is advocating for expedited progress in exploration operations, targeting advancements as early as H2 2026. The overall pace of development will hinge on Chevron’s final investment decisions and the speed at which state approvals are secured. If these projections materialize, Greece may soon transition from preliminary licensing and studies to active offshore exploration within two years.
