Israel began producing natural gas from its own offshore gas fields in 2004. Between 2005 and 2012, Israel had imported gas from Egypt via the al-Arish–Ashkelon pipeline, which was terminated due to Egyptian Crisis of 2011–14. In 2009, a natural gas reserve, Tamar, was found near the coast of Israel. A second natural gas reserve, Leviathan, was discovered in 2010. The natural gas reserves in these two fields (Leviathan has around 19 trillion cubic feet) could make Israel energy secure for more than 50 years. In 2013, Israel began commercial production of natural gas from the Tamar field. , Israel produced over 7.5 billion cubic meters (bcm) of natural gas a year. Israel had 199 billion cubic meters (bcm) of proven reserves of natural gas as of the start of 2016.
