The Cooper Basin
On the geologic time scale, 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. The Cooper underlies the southwestern Eromanga Basin (or Great Artesian Basin, a major water resource) and this region is referred to as the 'Cooper Eromanga Basin'.
Covering an area of one million square kilometres of central Australia, the Eromanga Basin is Early Jurassic to Late Cretaceous in age. The Cooper and Eromanga basins are intracratonic.
The centre of the Cooper Eromanga Basin is at approximately -28.097937, 140.200935Latitude: 28°5′52.573″S
Longitude: 140°12′3.366″E

Cooper Basin in South Australia
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.
The Cooper Eromanga Basin is situated mainly in northern South Australia and is located where the Cooper Basin is 'overlain' by the much larger Eromanga Basin which has an area of 1 million km2 in central-eastern Australia, 360000 km2 of which lie in South Australia[1].

Co-produced water, brought to the surface as part of petroleum exploration and production, peaked in 1994, with a total of about 34 ML/d (12499 ML/yr) from Eromanga (31 ML/d) and Cooper (3 ML/d). As at early 2009 rate was about 17 ML/d (6200 ML/yr)[2]
