Bonaparte Basin

Its total area is approximately 270,000 square kilometres (100,000 sq mi), most of which is offshore.

[1] The basin originated from the Cambrian period to the Cenozoic era, 540 to 360 million years ago.

Limestone, sandstone, mudstone, basalt, coal and glacial sediments are embedded in the basin.

Total estimated reserves are 29 million barrels (4.6×10^6 m3) of oil and 860 petajoules (2.4×1011 kWh) of gas.

There were studies on petroleum and natural gas,[3] which have resulted in oil and gas-producing wells and two undersea pipelines to the Northern Territory.
