Work starts on Leviathan field’s first phase - OIL & GAS JOURNAL

By OGJ editors

Wood Group has begun detailed engineering for the 30,000-ton fixed platform to be installed offshore Israel to handle production from deepwater Leviathan natural gas field (OGJ Online, Feb. 23, 2017).

Operator Noble Energy Inc. has drilled two of the four wells to be completed subsea in about 5,200 ft of water during the first development phase. Each will be able to produce more than 300 MMcfd of gas.

Twin 73-mile, 18-in. flowlines will carry production to the platform, which will be set in 270 ft of water about 6 miles from shore.

With a deck weight of 22,000 tons, the platform will have three processing trains with capacities of 450 MMscfd each.

Processed gas will flow into the Israel Natural Gas Lines Ltd. onshore transportation grid at Dor in northern Israel.

Noble estimates gross capital costs for first-phase development at $3.75 billion and gross reserves related to the investment at 9.4 tcf of gas. Leviathan holds gross recoverable resources of 22 tcf.

Production from the first phase is to start by the end of 2019 at 1 bcfd.

Noble expects all production wells to be completed next year.

A second development phase would add 900 MMcfd of Leviathan production capacity from four new wells, two processing trains, four compression trains of 300 MMcfd each, and a third tie-back flowline.

Leviathan interests are Noble 39.66%, Delek Drilling and Avner Oil Exploration 22.67% each, and Ratio Exploration (1992) LP 15%.
