Chevron Approves Leviathan Gas Expansion, Locking in Eastern Mediterranean Supply Growth

Chevron and its partners have taken a final investment decision to expand production at the Leviathan gas field, committing capital to a project that will anchor Eastern Mediterranean gas supply well into the next decade.

The decision formalizes a long-anticipated expansion aimed at lifting output from one of the region’s most strategic offshore assets. Leviathan supplies Israel’s domestic market and exports gas to neighboring states, notably Egypt and Jordan, making it a central node in cross-border energy flows.

The expansion scope includes additional offshore wells, new subsea infrastructure, and upgrades to the existing production platform. Once completed, total gas delivery capacity is expected to rise to around 21 billion cubic meters per year, with increased volumes scheduled to come online toward the end of the decade.

Chevron framed the investment as a response to sustained regional demand and as a signal of long-term confidence in Eastern Mediterranean gas development. Company executives emphasized that Leviathan’s output underpins energy supply for multiple markets while supporting regional energy security through stable, large-scale production.

Discovered in 2010 and producing commercially since late 2019, Leviathan ranks among the largest offshore gas fields in the Mediterranean basin. Chevron operates the project through its Mediterranean subsidiary alongside local partners, holding a leading role in operational and investment decisions.

The final investment decision moves Leviathan’s next phase from planning into execution at a time when gas supply security, export capacity, and infrastructure resilience are becoming increasingly intertwined with regional geopolitics. With expansion now approved, Leviathan is set to reinforce its position as a cornerstone of Eastern Mediterranean gas supply rather than a marginal growth project.
