Environmental Management Authority (NOPSEMA).

According to

abandonment the Yodel-Three and Yodel-Four manufacturing wells, and the Capella 1
exploration effectively.

Permanent
plugging will contain eradicating short-term plugs and putting in everlasting
abandonment obstacles within the wells utilizing a cell offshore drilling unit (MODU).

Woodside will
go away the Echo Yodel subsea infrastructure in-situ completely to allow the infrastructure
to proceed to supply a tough substrate to take care of the marine development and
habitat that at the moment helps native ecological capabilities.

The proposed petroleum
actions program is scheduled to happen between the primary quarter of 2021 and
fourth quarter of 2023.

Permanent
plugging actions for the three wells is predicted to take about 20 to 60 days
per effectively to finish. If carried out as a single marketing campaign, the cumulative
length might be as much as 180 days, together with mobilisation and demobilisation.

As for the
infrastructure that will likely be left in-situ, it consists of the Yodel-Three and Yodel-Four Xmas
timber, pipeline, umbilical, infield umbilical termination basket, umbilical
termination assemblies, and the pig launcher.

It is value
noting that the actions don’t overlap with any established or proposed
marine protected areas with the closest nearshore delicate habitats being the boundary
of the Montebello Australian Marine Park some 24 kilometres to the south.
