"Since 2009, a series of large natural gas discoveries in the Levant Basin have altered the dynamics of the Eastern Mediterranean region. Israel's discovery of the Tamar Field and subsequent discovery of the larger Leviathan Field created the potential for the country to become a regional player in the natural gas market. Since the initial Israeli discoveries, Cyprus and Egypt have also found new gas deposits in the Mediterranean. The Aphrodite Field was discovered by U.S. firm Noble Energy in Cypriot waters in late 2011 and the massive Zohr Field was found in Egyptian waters by Italian firm Eni in 2015.These discoveries create the potential for Cyprus to export gas and for Egypt to meet more of its domestic gas needs. Lebanon has not yet discovered recoverable gas reserves, but geologic data indicates that there is the potential for Lebanon to possess significant gas resources. Israeli gas discoveries have been contested by Lebanon, which disputes an area of about 300 square miles along the countries' unsettled maritime border. The Administration has sought to mediate the maritime dispute between Israel and Lebanon."
