Amplitude Energy Limited is an ASX-listed gas production company headquartered in Adelaide. It owns and operates offshore gas fields in Commonwealth waters and onshore processing plants in the Otway and Gippsland Basins, and holds non-operated oil production in the Cooper Basin.

Amplitude Energy (ASX:AEL) reported that the Annie-2 development well has been cased and completed and is being suspended, to be made ready for development as part of the East Coast Supply Project (ECSP).
Annie-2 reached a total depth of 2,253m MD on 28 October 2026 and a clean-up of the well was undertaken on 9-10 November 2026. The company says data to date indicates a significant improvement in permeability, porosity and deliverability compared to the initial discovery. The well recorded 43.6 metres net pay in the Waarre C formation sands. A peak, surface-constrained flow rate of 58.8 MMscf/day was achieved, and the main flow period recorded an average stabilised gas rate of 57.2 MMscf/day, with no formation water recovery recorded. The company says the programme is well ahead of schedule and budget, with none of the general contingency budgeted for the ECSP drilling programme consumed to date. Amplitude Energy holds a 50% interest in VIC/L37 and has recorded a gross Contingent Resource of 65 PJ (32.4 PJ net to AEL) for Annie on a 2C basis. The Transocean Equinox rig will next drill the Nestor exploration prospect.
The peak rate was constrained by surface test equipment, not well deliverability. Interpretation is ongoing, no estimate of reserves or contingent resources is reported in this release, and Annie and Juliet Reserve estimates are still being worked on.
