Australia Pacific LNG/ APLNG - Australia Pacific LNG Pty Limited. Australia Pacific LNG is a joint venture between Origin Energy (42.5%), ConocoPhillips (42.5%) and Sinopec (15%), to develop Australia's largest 2P coal seam gas reserves. The Project includes the development of Australia Pacific LNG's coal seam gas resources in the Surat and Bowen basins in central south west Queensland, a 530km transmission pipeline, and a multi-train LNG facility on Curtis Island, near Gladstone. The Australia Pacific LNG Project will become a supplier of low emissions fuel to growing international energy markets as well as continuing to contribute cleaner energy through its domestic gas production equivalent to more than 40 per cent of Queensland's current gas requirements.
Bbl - barrel
Bcf - billion cubic feet of gas

Bowen Basin - an area of over 60,000 km2 in Central Queensland in which Australia Pacific LNG has CSG interests.
BTEX - benzene, toluene, ethyl benzene, and xylene.
Conventional Gas - gas extracted from conventional petroleum reservoirs. Compared with CSG and other forms of gas which are derived from other forms of reservoirs. These are referred to as Unconventional Gas.
CSG - coal seam gas (gas extracted from underground coal seams)

Factors used by Origin to convert to PJe (Petajoules equivalent)
This measurement is used by Origin to represent the equivalent energy in different products.
One million barrels crude oil = 5.83 PJe
One million barrels condensate = 5.41 PJe
One million tonnes LPG = 49.3 PJe
One terawatt hour (TWh) of electricity = 3.6 PJe
Conversions
1 Gigajoule - 1 billion joules (109)
1 Terajoule - 1000 gigajoules (1012)
1 Petajoule - 1 million gigajoules (1015)
1 barrel of oil equivalent (BOE) - 5,658.53 cubic feet of natural gas
1 barrel (bbl) - 42 US gallons, or 34.97 Imperial gallons, or 159 litres
1 million tonnes (Mt) LNG - 1.44 Bcm gas
1 therm sales gas - 1.055 KJ
1 kilojoule - 0.9478 BTU
