The Cooper Basin (English: Cooper Basin ) is a 130,000 km² sedimentary basin in Australia , which is partly in the northeastern part of South Australia (portion; 35,000 km²) and extends to the southwest of Queensland . It is named after Cooper Creek , which flows into Lake Eyre . The Cooper Basin originated from the late Carboniferous to the Middle Triassic . The sediments are 1250 to 3670 meters thick .
The nature in the Cooper Basin is mostly desert-like and includes parts of the Simpson Desert , Channel Country and the Sturt Stony Desert .
Energy sources
mineral oil and natural gas
The Cooper Basin is the area of the most significant oil and gas reserves on mainland Australia, discovered in the 1960s. The first gas deposit, Gidgealpa 2, was discovered in 1963. Pipelines transport the natural gas to Brisbane , Adelaide and Sydney .
The largest producer of oil and natural gas in the Cooper Basin is Santos Limited with production facilities in Moomba .
The oil and gas deposits in the Cooper Basin are small in volume and widely fragmented. There are eight geothermal springs and 1,800 for oil and gas extraction that are used economically. Few companies are active in the Cooper Basin area that exploit the deposits in this region. For crude oil and natural gas production, these are Austin Exploration Limited, Cooper Energy, Beach Petroleum Limited, Innamincka Petroleum, Magellan Petroleum, Impress Energy and others; in geothermal energy it is Geodynamics Limited.
Geothermal energy
The companies that investigated the Cooper Basin were looking for a large recovery. While drilling at a depth of 3500 meters, they encountered granite at a temperature of around 240 ° C and the Cooper basin was selected for a geothermal project. The stone deposits are considered to be the hottest in the world, which are located at an economically acceptable drilling depth and not in the vicinity of volcanoes. When the reservoir was drilled, there was a small earthquake with a magnitude of 3.7 on the Richter scale .
