Project Profile

Value: US$37,000 million
Location: Barrow Islands, off the Pilbara coast, 85 Kilometers north – north – east of onslow and 140 Kilometres west of Karratha
LNG: 15 Million tonnes per year

The projects will see the proposed establishment of a midstream development, which will includes an LNG facility on Barrow Island, which lies directly between the gas fields and the mainland. The LNG plant will have three trains, with a nominal capacity of 5 million tonnes per annum each (Train 1 due online 2014). The LNG plant can only be 300 hectares big under the 2003 Barrow Island Act. The joint venture partners have letters of understanding for the long-term supply of up to 4 million tonnes of LNG per annum to North American West Coast. There will also be a domestic gas plant, with a capacity of 256 MMcf/d (300TJ/d) is part of the project.

The CO2 re-injection scheme would transport produced CO2 from the Gorgon field and re-inject it into the Dupuy reservoir 2,500m below Barrow Island. If successful, the intended technology would reduce the LNG project’s CO2 emissions from 9.5 million tonnes per year to 3.5 million tonnes per year.

The Gorgon reservoir has 12.9tcf of gas in a water depth of 220m. It is also high in CO2 (in the 10-15% range) and is HT/HP (130 degrees c/360 bar). The Jansz Reservoir is lean with low co2 (1%) and is located in 1350m of water. There are plans to increase the capacity of the trains to 7/8 mtpa. The Final Investment Decision was approved on 14 September 2009.

Gorgon condensate has an API gravity of about 52.9 degrees and a sulphur content of 0.0088%.
