JERUSALEM, Aug 7 (Reuters) - Israel’s Leviathan natural gas field has signed the largest export agreement in the country’s history, worth up to $35 billion to supply gas to Egypt, NewMed , one of the partners in the field, said on Thursday.

Leviathan, off Israel’s Mediterranean coast with reserves of some 600 billion cubic metres, will sell about 130 bcm of gas to Egypt through 2040, or until all of the contract quantities are fulfilled.

The Leviathan reservoir began supplying Egypt shortly after production began in 2020. It signed an initial deal in 2019 for 60 bcm - or 4.5 bcm a year - that is expected to be fully supplied by the early 2030s.
