On January 17, 2009, Israel’s economy and even its strategic stature changed when a team led by the Texan firm Noble Energy discovered gas in the Tamar field in the eastern Mediterranean, which is estimated to contain 9.7 trillion cubic feet (TCF) of natural gas. The Tamar well-heads which contain methane gas are rated at a high level of purity, with an energy value of production per well-head over four-fold higher than Saudi oil well-heads. Two years later, the same team drilling a few dozen kilometers further west discovered a monstrous gas field, appropriately called Leviathan, which is now estimated to contain 18 TCF and could begin supplying gas in 2016.
