Scope
- 300 ha of land has been acquired on Barrow Island
- 3x5 MTPA LNG Trains
- 15 million tonnes of LNG per year
- 300 terajoules per day domestic gas plant
- Ground breaking occurred on 1 December 2009
- First LNG in 2014
- Production ends between 2054–2074
Using initially 18 wells, gas will be delivered via subsea gathering systems and pipelines to the north-west coast of Barrow Island, then via an underground pipeline system to gas treatment and liquefaction facilities on the island's south-east coast. The plant will consist of 3 liquefied natural gas (LNG) trains, each capable of producing a nominal capacity of five million tonnes per annum (MTPA).
Carbon dioxide (CO2), which comprises around 15% of the raw gas stream, will be stripped out then injected into formations deep below the island. This forms a very large carbon capture and storage project, with 3.4 to 4 million tonnes of CO2 planned to be stored each year.
LNG and condensate, initially stored in onshore tanks, will be offloaded from a 2100m jetty onto LNG carriers and oil tankers, for delivery to overseas customers.Natural gas for domestic use will be exported by a 70 km subsea pipeline to the mainland, for transmission to local customers.
On the total investment of the Gorgon LNG project, media articles have reported analyst forecasts of estimated costs ranging from A$11 billion (in 2003), A$16 billion (2007), and A$50bn in March 2009 to A$43b in Sept 2009. Chevron, however, mentioned in September 2011 that the foundation phase will cost about US$29bn and consists of two LNG processing trains with combined capacity of 8.9mtpa.

Famous quotes containing the word scope:
“As the creative adult needs to toy with ideas, the child, to form his ideas, needs toys—and plenty of leisure and scope to play with them as he likes, and not just the way adults think proper. This is why he must be given this freedom for his play to be successful and truly serve him well.”
—Bruno Bettelheim (20th century)
“The scope of modern government in what it can and ought to accomplish for its people has been widened far beyond the principles laid down by the old “laissez faire” school of political rights, and the widening has met popular approval.”
—William Howard Taft (1857–1930)
“Every person is responsible for all the good within the scope of his abilities, and for no more, and none can tell whose sphere is the largest.”
—Gail Hamilton (1833–1896)
