Dolphin 1 partners Noble Energy Inc., Delek Group Ltd. and Ratio Oil Exploration have found clear signs of natural gas at the Dolphin 1 exploratory well in the Hanna license. The preliminary results found 550 billion cubic feet (15.7 billion cubic meters) of natural gas - about half the size of Yam Tethy's Mari B well, which has been in operation since 2004.
The Dolphin 1 discovery is Noble Energy and Delek's sixth straight natural gas discovery in Israeli waters: Noa in 1999, Mari B in 2000, Tamar and Dalit in 2008, and Leviathan in 2010.The Dolphin 1 well is the most promising of the three geologic structures in the Hanna license. The gas bearing strata are located in a structure known as the Tamar sands at a depth of 4,440 meters in waters 1,560 meters deep. The prospect is located 110 kilometers west of Haifa.
