Transocean rig to drill Nestor after Annie-2 completion offshore Australia

Amplitude Energy has completed the Annie-2 gas well in the Otway Basin, with results indicating better reservoir quality and deliverability than the 2019 discovery well.

The Transocean Equinox semisubmersible rig has cased and completed the Annie-2 gas well in the Otway Basin offshore Victoria with a subsea tree, according to operator Amplitude Energy.

The well reached a total depth of 2,253 m MD on Oct. 28, and underwent cleanup earlier this week.

Data from the well has confirmed a good-quality reservoir, and better permeability, porosity and deliverability compared to the initial discovery well made in 2019.

The well is currently being suspended ahead of development for Amplitude’s East Coast Supply Project (ECSP).

Transocean Equinox will then relocate to drill the Nestor exploration prospect, the final well of the ECSP drilling campaign.

Annie-2 is in permit VIC/L37, 10 km north of its planned tie-in point to the existing CHN pipeline.

O.G. Energy is the other partner.
