Delek Drilling is a limited partnership formed in 1993 as a subsidiary partnership of the Delek Group, which is controlled by entrepreneur and businessman Yitzhak Tshuva. The partnership is active in exploration, development, production and sale of natural gas, crude oil and condensate. The Delek Group Ltd. holds (indirectly) 100% of the share capital of Delek Drilling Management (1993) Ltd., the general partner in Delek Drilling, alongside the limited partner, which serves as a trustee and holds the participation units issued by it in trust for the unit holders. These units confer participation in the limited partner’s rights in the partnership. Delek Drilling is traded on the TA-25 Index on the Tel Aviv Stock Exchange. Delek Drilling, together with its partners Avner Oil Exploration and US company Noble Energy, Inc., has been an active and prominent partner in all the significant gas discoveries made in the exclusive economic zone (EEZ) of Israel as of the final decade of the 20th century through to the present. In 2009, the discovery of the Tamar and Dalit fields 100 kilometers off of Israel’s northern coast by Delek and its partners marked a major turning point for the Company and for Israel’s energy sector as a whole. Tamar was the world’s largest natural gas discovery in 2009. Tamar’s and Dalit’s reserves are estimated today to contain over 9 trillion cubic feet (TCF) of natural gas, a quantity sufficient to meet Israel’s natural gas needs for over 20 years. In late 2010, Delek struck the largest natural gas find in Israel’s history at the Leviathan well. Both Tamar and Levi-athan are the largest deepwater gas discoveries in the world in the past decade.
