The Lebanese energy sector received a boost a few years ago with the discovery of potentially large gas and oil fields in the Eastern Levant basin - resulting in the issuing of licences for drilling to three large companies this year. 

But a major find in Lebanon's southernmost waters could raise the possibility of a dispute with Israel, which is developing a number of offshore gas deposits, with one large field, Tamar, already producing gas, and the larger Leviathan field set to go online next year.
