Spanning the borders of north-east South Australia and south-west Queensland, the Cooper and Eromanga Basins house Australia’s largest onshore oil and gas field development. Santos discovered the first commercial hydrocarbon resource (natural gas) here in 1963 and first oil in 1970.

Santos now produces sales gas, ethane, crude oil and gas liquids from these basins.

The Cooper Basin asset is strategically important, housing key processing infrastructure at Moomba integral to the processing and transportation of gas around the east coast of Australia, supported by substantial underground storage facilities.

Raw gas and ethane are processed at the Moomba plant, South Australia, and then piped to domestic east coast gas markets as well as the GLNG project for export to Asia. 

Natural gas liquids recovered at the Moomba plant are sent together with stabilised crude oil and condensate via a 659 kilometre pipeline to Port Bonython, South Australia, for further processing. Products including naphtha, crude oil, propane and butane are sold to domestic customers via the road tanker loading facilities and export customers via the ship loading facility.

Santos is committed to building production, investing in new technology and increasing the utilisation of our infrastructure to drive efficiencies and deliver a low-cost, cash flow positive business.
