Vintage Energy Ltd. has begun its planned fracture stimulation program at Vali gas field in southwest Queensland Cooper basin permit ATP 2021.
The campaign, expected to take 42 days, involves fracturing the gas-bearing Permian-age Patchawarra formation reservoir across multiple zones in the Vali-2 and Vali-3 wells.
Fracturing at discovery well Vali-1ST is complete, Vintage said.
The campaign is a prelude to completion of all three wells for gas production for sale to AGL under a March sales agreement.
Work is being carried out by Schlumberger and supervised by Griffin Energy Solutions.
Production from the Patchawarra will be supplemented by flows from another reservoir in the Toolachee formation, the company said.
Vali field is to be connected to the Moomba gas gathering network in South Australia with the gas destined for the eastern Australian domestic market.
Vali field has been independently assessed as containing 2P reserves of 101 petajoules.
Vintage is operator with 50% interest. Metgasco Ltd. and Bridgeport (Cooper Basin) Pty Ltd. each hold 25% interest.
