Israel is examining its policies and options for exporting natural gas in light of the vast gas discoveries made offshore Israel in 2009 [the Tamar field, with 11 trillion cubic feet (Tcf) of reserves] and in 2010 (the Leviathan field, with 20 Tcf), as well as the smaller Tanin field (1.1 Tcf) in 2011 and the Karish field (1.8 Tcf) in 2013. In June 2013, the government of Israel sanctioned the export of 40% of these proven reserves.
