Leviathan gas field, which is located in the Mediterranean Sea in 135km from the Israeli Haifa, was discovered in 2010 by the American Noble Energy Company, which concluded contract with Israeli government back in 2008 on initiating joint gas and oil exploration in the Mediterranean. The gas reserves found in 2010 can be considered rather impressive as, according to Noble Energy the total natural gas reserves in this field are estimated up to 450 billion m3 which makes it one of the biggest gas fields in the world. The importance of Leviathan for Israel is conditioned by the fact that it will exempt the Jewish state from the energy dependence on Egypt, which imports exports gas to Israel. Taking into consideration that the political processes going on in Egypt since 2011 can bring to power “Muslim brothers”, who are of radical anti-Israeli orientation, discovering and processing of a gas field of its own has become for Israel an issue of paramount national importance.
