The ATP 2021 joint venture (JV) (Vintage 50% and operator, Metgasco Ltd 25% and Bridgeport (Cooper Basin) Pty Ltd 25%) awarded the Vali-1 ST1 fracture stimulation activities to Condor Energy Services Pty Ltd (Condor) in June, with Condor currently mobilising its equipment to site. This is expected to be completed over the coming days.
The Vali-1 ST1 fracture stimulation programme is planned to be six stages, five in the Patchawarra section and one in the deeper Tirrawarra / Basal Patchawarra section, at depths of between 2810 m to 3140 m. The previously successful casing pressure test, cement bond logging and baseline temperature log, have all provided important information for the design of an effective fracture stimulation programme.
Flow testing will record gas flow rates from the Patchawarra Formation and Tirrawarra Sandstone, where gas was recovered during drilling operations. The objectives of the flow testing programme will be to measure total stabilised gas rates, downhole reservoir pressure and individual zonal gas flow contribution. The results of the fracture stimulation and flow testing programme will be assessed and incorporated into a commercialisation plan for the asset.
Vintage Managing Director, Neil Gibbins, said: “The fracture stimulation of the Vali-1 ST1 well is the first of two key steps that will provide an indication of the gas flow capability of the Vali discovery. It is pleasing that all activities are on schedule to this point and we look forward to again working with Condor to complete a safe and hopefully successful stimulation operation at Vali-1 ST1.
“Vali is an important step for Vintage as we look to evolve beyond exploration and appraisal into production. The recent successful gazettal bid for Block CO2019-E (PELA 679) near Moomba, the Odin Structure in PRL 211 and the numerous prospects and leads in ATP 2021, all add up to a material footprint for Vintage in the Cooper Basin, an area where our technical team has had much success over the years.”
