Amplitude Energy took a final investment decision on the development phase of its East Coast Supply Project in the offshore Otway Basin, off Victoria, and agreed with partner O.G. Energy to drill the Nestor exploration well.
Development plan
The Annie, Juliet and Artisan fields are designed to deliver gross production of up to about 90 terajoules a day through the Athena Gas Plant, for at least four years from first gas, targeted for 2028. The development scope covers subsea installations and plant modifications during fiscal 2028. It remains subject to completion of Amplitude's acquisition of the Artisan field.
Nestor and the rig program
The Juliet-1 exploration well, drilled in permit VIC/L24, has been completed and is being suspended for future development. A flow test there peaked at a surface-constrained 56,700 mcf/d, with 61 meters of gross pay and 52 meters of net pay found in the Waarre C formation. Gas samples showed about 1% carbon dioxide and 2% nitrogen.
The Transocean Equinox semisubmersible will move to the Annie discovery this week to begin the Annie-2 development well. Nestor will be drilled after Annie-2 with the same rig, as an optional well preserved in the current campaign. Engineering and design work is complete, and all regulatory approvals are in place. If Nestor finds gas, the well will be completed during the current campaign using the same one-touch approach as the rest of the ECSP program, and could be commercialized as early as 2028 through existing Otway infrastructure.
| Well | Result |
|---|---|
| Juliet-1 | 56,700 mcf/d peak flow (surface-constrained), 61 m gross / 52 m net pay, Waarre C formation |
| Annie-2 | Development well, drilling starts this week |
| Nestor | Optional exploration well, drilled after Annie-2 |
