Woodside Energy Ltd (Woodside) currently operates the TPA03 production well located approx. 138km north-west of Dampier in permit area WA-5-L. TPA-03 is a dual zone well connected to the Tidepole manifold and is produced by the Goodwyn Platform via subsea tieback before being exported to the interfield line (IFL) and to the Karratha Gas Plant for processing. The well is currently operated under the accepted Goodwyn Alpha Facility Operations Environment Plan (March 2022).

Woodside proposes to conduct well intervention activities at the TPA03 well to remediate a down-hole valve and continue production from the lower reservoir. Once the well intervention has been completed, the well will be shut-in until production is required. The shut-in and subsequent return to production of the well will be managed under the accepted Goodwyn Alpha (GWA) Facility Operations Environment Plan (March 2022) as part of ongoing operations.

The TPA03 well is located in approximately 113 m water depth. Activities are currently anticipated to be completed around H1 2024 with contingency in 2025. The timing and direction of the proposed activities is subject to change due to approvals, project schedule requirements, vessel availability, weather or unforeseen circumstances.
