TOKYO – INPEX has started production from the Ichthys LNG project offshore/onshore northwest Australia.

Gas has started flowing from the first offshore production well following the completion of final safety verifications including additional measures concerning electrical equipment.

Produced gas/condensate from the Ichthys field’s subsea wells, in 260 m (853 ft) water depth, heads to thecentral processing facility (Ichthys Explorer) for separation into gases and liquids.

At peak the offshore facilities will produce 1.6 MMcf/d of gas and 85,000 b/d of condensate.

The separated liquids will travel through a short pipeline to the nearby FPSOIchthys Venturer for storage and subsequent offloading to tankers.

Gas will be transported via the 890-km (553-mi) long gas export pipeline to the onshore gas liquefaction plant at Darwin, Northern Territory.

On arrival, the gas will undergo further separation and liquefaction to produce liquefied petroleum gas (LPG) and liquefied natural gas (LNG).

The two-train plant will eventually produce around 8.8 MMt/yr of LNG for the Asian market, 1.65 MMt/yr of LPG, and an additional 15,000 b/d of condensate.

INPEX’s partners in the project are Total, CPC Corp, Taiwan, Tokyo Gas, Osaka Gas, Kansai Electric Power, JERA, and Toho Gas.
