Vintage Completes Concept Designs for Oz Vali Field
The ATP 2021 joint venture - comprising Vintage Energy, Metgasco and Bridgeport - has completed concept designs for developing the Vali field in Queensland, Vintage said on September 17 in a statement. The field is expected to have a production life of around 20 years.
“The data used for the development concept was generated from the highly successful flow test of Vali-1 ST1, which delivered a stabilised gas rate over a two-day period of 4.3mn ft3/day through a 36/64” choke at 942psi,” Vinatge said. Vali-1 ST1 is due to be completed next month.
The plan envisages nine fracture stimulated vertical wells that will target reservoirs in the Patchawarra Formation and the Tirrawarra Sandstone. The first two wells are slated to be drilled in first half of 2021, and will also appraise upside potential in sands within the Toolachee Formation and Nappamerri Group, Vintage said.
The nine wells will be tied a central manifold, with gas to be transported via multiple composite pipelines to the Santos-operated Beckler field and then into the Moomba gathering system.
“We will be initially targeting approximately four petajoules per annum of gross gas production, and I am of the belief this could be increased substantially with appraisal and exploration success in the area,” Neil Gibbins, Vintage managing director, said.
The Vali discovery in Queensland was announced in January this year. Vinatge is the operator with a 50% interest while Metgasco and Bridgeport each own 25%.
