Woodside proposes to conduct well intervention activities within the North Shelf Project to remediate a down-hole valve and continue production from the lower reservoir. The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) recently gave the company the green light to go ahead.
The North West Shelf Project, which has been in operation since 1985, comprises the Goodwyn A (GWA), Angel, and North Rankin production platforms, and associated subsea infrastructure. The facilities are operated by Woodside on behalf of the North West Shelf Project participants.
The intervention activities are set to take place at the TPA03 well, operated by Woodside and located approximately 138km north-west of Dampier in permit area WA-5-L. TPA-03 and in 113m water depth.
It 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.
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 in March 2022 as part of ongoing operations.
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.
