Shell FLNG gas production

Shell finally starts production from its Floating Natural Gas Unit (FLNG) Prelude asset in Australia, marking the first phase of operations of this nature in the region

The FLNG unit is located in the Browse Basin, approximately 475 km north-northeast of Broome, Western Australia. The project is operated by Shell with a 67,5% stake, with Inpex (17,5%), CPC (5%) and KOGAS (10%) as partners. Shell introduced the gas aboard Prelude FLNG for the first time in June 2018. Gallina, a Singapore-based LNG carrier, performed the import. The next step was to test and prepare the LNG plant aboard the Prelude in preparation for opening the wells.

The opening of the wells and the start of production were announced on Wednesday, December 26th by Inpex, which is involved in the development of the Project in Block WA44-L off the west coast of Australia through its subsidiary Inpex Oil & Gas Australia Proprietary Limited (YOGA).

The Prelude FLNG facility will separate and liquefy gas produced from the well to produce liquefied natural gas (LNG), liquefied petroleum gas (LPG) and condensate. These products will then be loaded directly from the FLNG facility to the tankers and shipped in sequence.

YOGA's equity portion of the LNG produced through the project is expected to be supplied to JERA (approximately 0,56MTPA) and Shizuoka Gas (approximately 0,07MTPA) in the plateau production volume, thus contributing to the stable supply of energy to Japan.

O project involves the development of the Prelude and Concerto gas field located 475 kilometers north-northeast of Broome, on the west coast of Australia, and separating and liquefying the gas produced at the FLNG facility. Prelude FLNG is the first FLNG project in Inpex's portfolio.

Built by the Technip-Samsung consortium, the 488 meter long and 74 meter wide FLNG unit left the shipyard in South Korea at the end of June 2017 and reached Australian waters at the end of July. All 16 mooring lines at the Prelude field were connected in August of the same year.

The largest floating facility ever built will unlock new energy resources at sea and produce approximately 3,6 million tonnes of liquefied natural gas (LNG) per year. It will remain in place through all weather events and is designed to withstand a Category 5 cyclone. The FLNG will remain in place for 20-25 years.
