The Vintage Energy Ltd.-led joint venture in southwest Queensland Cooper basin permit ATP 2021 completed the development concept for Vali gas field.
Vintage estimated field life of 20 years with first production and cash flow expected during the third quarter of the 2021 financial year.
The JV plans nine fracture stimulated vertical wells targeting the Patchawarra formation and Tirrawarra Sandstone reservoirs—both both of Permian age. The first two will be drilled during first-half 2021, subject to regulatory and joint venture approval and rig availability.
Upside potential in sands within the Toolachee formation and Nappamerri Group will be appraised.
All wells in the development connect to a central manifold, with gas transported via multiple composite pipelines to Santos-operated Beckler field and on into the Moomba gathering system for processing at the Moomba plant.
Vintage is initially targeting production of 4 petajoules/year.
Development is based on recent well tests at the Vali-1 ST1 sidetrack (OGJ Online, Aug. 6, 2020). The base case is for production of 5 million cu ft of gas per well.
Surface facilities at Vali will be kept to a minimum.
A new field reserve assessment is under way. The current independently certified 2C contingent resources are estimated at 37.7 bcf (OGJ Online, Mar. 3, 2020).
Vintage is operator with 50%. Metgasco Ltd. and Bridgeport (Cooper Basin) Pty Ltd. each hold 25%.
