The growth came amid five-fold growth in offshore gas production since the start-up of Israel's first major producing Tamar field in 2013, the report prepared by consultancy BDO for the Israeli Natural Gas Trade Association said.

Israel's gas reserves grew from 780 billion cubic metres (bcm) in 2012 to 1,087 bcm at the end of 2022, while 119 bcm was extracted over the same period, the report said.

The growth in reserves was due to several new discoveries, including Energean's Olympus field, which has been renamed Katlan, as well as further exploration activity around hubs including the Chevron operated Leviathan field.

The eastern Mediterranean region has seen rapid expansion of natural gas production over the past decade, following the discovery of major resources in waters off Israel and Egypt.

The gas is supplied to the region via pipelines and in Egypt is also exported to international markets through gas liquefaction terminals.
