Houston-based Noble Energy Inc. is just months away from delivering commercial gas in Israel’s Leviathan field, with sales scheduled to start by the end of the year.

The $3.75 billion development, the largest energy project in the country’s history, recently saw the first of five topside units that would complete the Leviathan Platform set sail from the Gulf of Mexico. Following the assembly in Israel of the rest of the topsides in September, Noble says the company will conduct a series of commissioning tests before initiating commercial gas flow before the end of 2019.

The platform topside decks — 102 meters long, 80 meters wide and weighing 25,000 tons — would be located approximately 10 kilometers from the shore in a water depth of 86 meters.

The first phase of the estimated 22 Tcf development included four subsea wells, each capable of flowing more than 300 MMcf/d. The field holds 3.3 Tcf of proved reserves.

Noble expects to sell an average of 800 MMcf/d from Leviathan in 2020. Natural gas from the field will be transmitted through two 120-kilometer subsea pipelines directly to the Leviathan platform. Natural gas will be processed at the platform before the treated gas and stabilized condensate flow from the platform through a northern entry pipeline connected to the Israel Natural Gas Lines, the national gas transmission system.

The company operates Leviathan and holds a 39.66% working interest in the field, along with other partners Delek Drilling (22.67%), Avner Oil Exploration (22.67%) and Ratio Oil Exploration 1992 LP (15%).

With a total production capacity of 1.2 Bcf/d, Leviathan would more than double the quantity of natural gas flowing to the Israeli economy today.
