The Cooper Basin forms the most significant element of Australia’s largest onshore oil and gas province. Since the discovery of natural gas at Gidgealpa in 1963 and oil at Tirrawarra in 1970, 229 x 109 m3 (8.2 tcf) of recoverable raw gas and 6.9 x 106 kL (43.9 mmstb) of recoverable oil* have been found in South Australia at 1 January 1998. A total of 129 x 109 m3 (4.6 tcf) of gas and 4.6 x 106 kL (29.1 mmstb) of oil have been produced to date. The Tirrawarra Field contains 80% of known oil reserves; one-third of South Australia’s Cooper Basin gas reserves are in the Moomba and Big Lake gas fields. Pipelines supply Cooper Basin gas to Adelaide and Sydney as well as a number of regional centres, ethane to Botany Bay, and a liquids pipeline carries oil, condensate and liquefied petroleum gas (LPG) to Port Bonython.
The Cooper Basin is a Late Carboniferous to Middle Triassic, non-marine sedimentary basin which underlies the desert region of northeastern South Australia and South-West Queensland. One-third of the basin (35 000 km2; 13 500 square miles) is in South Australia; the unconformity at its upper surface varies in depth from 970 to 2800 m while the base of its deepest trough reaches ~4400 m below sea level.
* Numbers refer to Cooper oil only. Total recoverable oil (Cooper and Eromanga) in SA is 17.5 x 106 kL (110 mmstb).
