Amplitude completes Annie-2 development well offshore Victoria
Amplitude Energy drilled the Annie-2 development well to a total depth of 2,253 m measured depth on 28 October 2026 with the semisubmersible Transocean Equinox, then cased and completed it with a subsea tree. The well is in permit VIC/L37 in Commonwealth waters offshore Australia, about 10 km north of its planned tie-in to the existing Casino Henry Netherby (CHN) pipeline.
Data from the well indicate good reservoir quality, with a significant improvement in permeability, porosity and deliverability compared with the original Annie discovery. Gas composition samples match the discovery. Well clean-up ran 9 to 10 November, and Annie-2 is being suspended for development as part of the East Coast Supply Project (ECSP). The program is ahead of schedule, and Amplitude is updating reserve estimates for Annie and Juliet over the coming weeks.
The Transocean Equinox will move to the Nestor exploration prospect to drill the final well in the ECSP campaign. Amplitude holds 50% of VIC/L37, with O.G. Energy holding the other 50%.
