The partners in Israel's offshore natural gas field Leviathan said on Wednesday they signed a preliminary deal to supply gas to Egypt via an existing underwater pipeline to the Sinai peninsula. Under the deal, Leviathan -- which is expected to begin production in 2019-2020 -- would supply Egypt's Dolphinus Holdings with up to 4 billion cubic meters of gas a year for 10 to 15 years, the partners said in a statement to the Tel Aviv Stock Exchange. The price of gas is similar to other contracts and is linked to the price of Brent oil, they said. Dolphinus is a firm that represents non-governmental, industrial and commercial consumers in Egypt. Leviathan is owned by a group led by Texas-based Noble Energy and Israeli conglomerate Delek Group. http://english.ahram.org.eg/News/171694.aspx
