Santos Ltd, as Operator on behalf of the Patchawarra Southwest Block Joint Venture Parties, announces the discovery of a new gas field in the South Australian section of the Cooper/Eromanga Basins.

The block gas exploration well, Raven 1, flowed gas at 254,900 cubic metres per day (9.0 million cubic feet per day) with 56 API condensate at 26 kilolitres per day (165 barrels of condensate per day) from reservoir sands in the Early Permian, Patchawarra Formation, over the interval 2622-2632m. The test was run through a 13mm (0.5) surface choke.

The Raven 1 well is located 7km southwest of the Moonanga Field and approximately 47km westnorthwest of the Moomba Gas Plant.

The well has reached a total depth of 2987m. The well will be cased and suspended as a future gas producer.

The Raven 1 discovery is the 10th well to be drilled in an 11 well Patchawarra Southwest gas exploration program which commenced in late 1996. Nine of these wells have been successful with 8 new gas fields discovered. The final well in the program, Double Jay 1, will commence drilling following rig relocation.
