Natural gas seeps

GasFields Commission Queensland has undertaken a historical data search that has identified the existence of natural gas seeps from the Surat, Eromanga, Cooper, Georgina, Bowen and Galilee basins in Queensland.

These soil gas surveys demonstrate that landscape gas seeps existed naturally before the recent expansion of the onshore gas industry in Queensland.

For further information, visit the GasFields Commission Queensland website on historic landscape gas seeps data.
