In-situ gas-processing technique

Shell has announced plans to use an innovative in-situ gas-processing technique in its offshore gas field off the northwest coast of Western Australia.

Shell has announced plans to use an innovative in-situ gas-processing technique in its offshore gas field off the northwest coast of Western Australia.

The technique, known as Floating Liquefied Natural Gas (FLNG), will be used for Shell's Prelude and Concerto gas discoveries located in the Browse Basin.

Shell argues that the ability to process gas in situ over an offshore gas field will reduce project costs and the environmental footprint of an LNG development.

The Prelude FLNG project is now in the front-end engineering and design (FEED) phase of development. FEED for Prelude is being undertaken as part of Shell's contract with the Technip-Samsung Heavy Industries consortium for the design, construction and installation of multiple FLNG facilities.

Malcolm Brinded, Shell’s executive director, upstream international, said the FLNG technology has the potential to unlock some of Australia's 'stranded' gas reserves that have previously been considered uneconomic to develop because of their small size or distance from shore.
