Santos Ltd, as Operator for the South West Queensland Unit, announces a successful gas exploration well in the Queensland sector of the Cooper/Eromanga Basins.

The exploration well, Roti West 1, flowed gas at 132,250 cubic metres per day (4.7 million cubic feet per day) with 55 kilolitres (345 barrels) of 61 API condensate per day from reservoir sands in the Permian Epsilon Formation over the interval 2295m – 2310m. The test was conducted through a 13mm (0.5) surface choke and was conducted over only one of the multiple gas bearing reservoirs in the well.

Roti West 1 gas discovery follows the successful Wippo East 1 well which also discovered gas from multiple horizons in the Permian aged Toolachee, Epsilon & Patchawarra Formations.

Roti West 1 is located 30km east of the Ballera Gas Centre and some 10km south east of Wippo East 1.

The well will be cased and suspended as a future gas producer.
