The Brisbane-based company yesterday said the Victoria Petroleum-operated joint venture is preparing to run a drill stem test of oil shows encountered in sands of the Birkhead Formation over the interval 1725-1732.8m.
Wirraway-1 is designed to test a large, four-way dip closed structure on the western margin of the Cooper Basin.
The prospect has a similar but larger structure to Growler and Wirraway-1 is the second well spudded by the current JV, which comprises VicPet (40%), Impress Energy (40%) and Roma (20%).
Wirraway-1 is 4km northwest and updip of the Growler-1 discovery, which found a 15m oil column and recovered 35 barrels of oil during an open-hole DST from the Birkhead Formation last September.
Located 15km west of Wirraway-1 lies the Santos-operated Callabonna oil discovery, which recovered 17bbl of oil in the Birkhead Formation back in 1990.
The JV has previously said the Wirraway prospect has the potential to contain 7.6 million barrels of P50 recoverable reserves in the Birkhead, while other Jurassic reservoirs were also prospective.
