The Tanin gas field (Hebrew: מאגר תנין‎‎, "Crocodile reservoir") is a natural gas reservoir located 120 kmoff the coast of Israel. It is the country's seventh natural gas discovery. On 5 February 2012 Noble Energy reported that the Ensco 5006 drilling rig (formerly the Pride North America) had struck gas at a depth of 5,500 m. Preliminary estimates put the potential for natural gas at Tanin at 1.2-1.3 trillion cubic feet. A subsequent report evaluated the field as containing 1.1 trillion cubic feet of natural gas: 0.6 TCF proven (contingent) reserves and 0.5 TCF prospective. Tanin is located within the Alon A license, in which three companies are partners: Noble Energy (47%), Delek Drilling (26.5%), and Avner Oil Exploration (26.5%). It is Israel's third-largest natural gas reservoir.
