Vintage Energy finds gas in Vali-2 appraisal
Vintage Energy Ltd., Adelaide, found gas in both key Permian-age reservoirs in its appraisal of the Vali gas discovery in the Cooper basin of southwest Queensland.
Logging data from the Vali-2 appraisal well confirmed gas in the Toolachee and Patchawarra formations. The well has been cased as a future producer.
One of the main objectives for Vali-2 was to assess the potential for gas in the Toolachee four-way dip closure, which was not tested in the Vali-1 ST1 discovery well.
Successful recovery of a wireline gas sample bodes well for an increase in the certified Vali field reserves which currently only reflect gas in the Patchawarra, the company said.
The Toolachee in Vali-2 is 6 m up-dip of Vali-1 ST1 while the Patchawarra was intersected 7 m high to prognosis. Based on the log response, the Patchawarra appears to have a greater amount of sand throughout, the company said.
Vali lies in permit ATP 2021. Vintage is operator with 50% interest. Partners are Metgasco Ltd. and Bridgeport (Cooper Basin) Pty Ltd. with 25% each.
The rig is being mobilized to the Odin-1 wildcat in permit PRL 211 in South Australia. The well is expected to spud in the next week.
The Odin structure is a large fault-bound Patchawarra formation closure derisked by the success at Vali.
