Royal Dutch Shell plans to use Floating Liquefied Natural Gas (FLNG) technology for the first time to develop its Prelude and Concerto gas fields near Western Australia's northwest coast.
Shell plans to develop the Prelude gas field in the Browse Basin, which contains 2 to 3 trillion cubic ft of recoverable gas, using a floating LNG vessel.
Shell's FLNG technology can process gas "in situ" over an offshore gas field, decreasing the environmental impact and project costs of an LNG development, the company said.
Shell’s executive director, upstream international Malcolm Brinded, said that the FLNG technology has the potential to unlock some of Australia’s "stranded" gas reserves.
These reserves were previously considered uneconomic to develop because of their small size or distance from shore.
Shell is the 100% equity owner and operator of the WA-371-P permit, comprising the Prelude and Concerto discoveries, which will be sequentially developed.
The Prelude FLNG project is currently in the Front End Engineering and Design (FEED) development phase, and is awaiting a final investment decision.
