Activity Description

Woodside currently produces hydrocarbons from the Pluto, Pyxis and Xena fields in Production Licence WA-34-L. This Environment Plan (EP) is a revision to the previously accepted WA-34-L Pyxis Drilling and Subsea Installation EP to include drilling and the development of one Pluto infill production well (PLA08). If required, Woodside will also include contingent activities including well intervention workover or re-drill of the Pluto, Pyxis and Xena production wells (PLA01 to PLA08, PYA01 and PL-PYA02, and XNA01 and XNA02) within Permit Area WA-34-L to monitor and maintain their integrity. The proposed PLA08 well will be tied back to the Pluto platform and operated under the accepted Pluto Facility Operations Environment Plan. The activities will be undertaken in Commonwealth waters around 170km north-west of Dampier and 50km south-east of the Montebello Islands, in permit area WA-34-L. The proposed PLA08 well will be located at approximately 820m water depth and will be tied back to the existing Pluto manifold by approximately 300m flexible jumper lines. PLA08 drilling and subsea installation activities are currently anticipated to commence in November 2023 and are expected to take approximately 50 days to complete. Installation of the subsea connections and cold commissioning is anticipated to commence within 1-9 months from when the well has been completed and is expected to have a cumulative duration of about 4 weeks. Well intervention or workover activities may require up to 70 days per well and may be carried out at any time during the in-force period of the EP, but only if required. The timing and duration of the proposed activities is subject to change due to project schedule requirements, vessel availability, weather or unforeseen circumstances. The duration of the EP is for two years, and all activities will be completed by 30 November 2025.
