New Cooper Basin Exploration Play Discovery: Wellington 1

Santos Ltd, as Operator for the South West Queensland Unit, announces the success of a new gas play in the Queensland sector of the Cooper/Eromanga Basins.

The Wellington 1 gas exploration well in Southwest Queensland has been cased and suspended as a Toolachee Formation gas producer.

Santos’ Managing Director Mr John Ellice-Flint said “The well successfully proved the existence of a stratigraphic trap in the Baryulah/Juno region 35 kilometres due south of the Ballera gas plant.
We intend to quickly complete connection of the well to the Baryulah trunkline before the end of November and follow-up appraisal activity is planned to assess the extent of the hydrocarbon accumulation.

This discovery fits well with Santos’ strategy of extracting additional value from its Cooper Basin assets.”

During an initial two-hour production test the Wellington 1 well flowed gas to surface at a calculated rate of 257,700 cubic metres per day (9.1 Million cubic feet per day) through a 12.5millimetre (1/2 inch) choke.

The interests of the Producers in the South West Queensland Unit are:

Santos Group (Operator)


Delhi Petroleum
