Two key Israeli gas fields are set to stop production and the country’s 197,000 b\/d Haifa oil refinery has shut down some units, in response to the US-Israel and Iran conflict.<\/p>\n
The US and Israel began a military operation against Iran today. Tehran has responded by firing missiles against Israel and against US military assets<\/a> in regional countries.<\/p>\n Israel’s energy ministry has instructed Greek firm Energean to temporarily suspend production at its offshore Karish gas field “following the recent geopolitical escalation in the region”, the company told Argus. A source said Israel has also ordered the closure of the country’s largest gas field, Leviathan, as a precautionary measure. Leviathan operator Chevron referred questions to the energy ministry. There is no indication of the status of Chevron’s other gas field in Israel, Tamar.<\/p>\n The Haifa refinery operator Bazan said it has shut down some unspecified units. Israel has another refinery, Paz Oil’s 110,000 b\/d Ashdod.<\/p>\n The shutdowns in Israel are some of the first effects of the conflict on regional energy infrastructure. These appear to be precautionary, given the Haifa refinery was severely damaged in a missile attack<\/a> during the 12-day war between Israel and Iran in June 2025.<\/p>\n Then, Leviathan and Karish were shutdown, and Tamar continued to produce uninterrupted.\u2028The shutdowns of the gas fields are likely to result in a steep reduction or complete halt to Israeli gas exports to Egypt, as happened last year.<\/p>\n The biggest effect of the conflict would be disruption to shipping lanes and energy movements through the strait of Hormuz, through which around 20pc of global oil supply and a significant share of LNG exports transit.<\/p>\n
