Chevron Corporation and its partners have taken a final investment decision (FID) for the expansion of production capacity at Leviathan natural gas field, an important offshore energy asset in the Eastern Mediterranean. The offshore gas field now targets an annual output of about 21 billion cubic metres (bcm). The sanctioned expansion by Chevron on the Leviathan natural gas field offshore Israel involves offshore drilling, subsea infrastructure and platform upgrades. Leviathan is planned to come online toward the end of this decade. The offshore gas field is also key to Israel’s domestic energy supply and with the expansion, it will be able to increase deliveries to regional markets including Egypt and Jordan.

The expansion project will include the drilling of three additional offshore wells, installation of supporting subsea systems, and upgrades to treatment facilities on the existing Leviathan production platform. These measures are expected to raise aggregate field output to approximately 21 bcm per year, nearly doubling current capacity. Chevron’s subsidiary Chevron Mediterranean Limited serves as operator, holding roughly 39.66 % equity, with partners NewMed Energy holding 45.34 % and Ratio Energies with 15 % completing the working interest group.

A Look at Leviathan Natural Gas Field Offshore Israel

Since its discovery off the coast of Haifa, Leviathan has been the largest gas field in the Eastern Mediterranean and a key asset in Israel’s energy portfolio. Commercial production began in 2019. This reshaped Israel’s energy dependence and security alongside its regional export dynamics. The decision by Chevron and partners for the expansion of Leviathan also comes as regional demand for gas continues to increase. This demand is driven by one of the largest gas export commitments in Leviathan’s history. This features a multi-billion-dollar sales arrangement with Egyptian offtakers who will use the Nitzana natural gas pipeline for supply.
