Chevron is shooting a big 4D marine seismic survey offshore Western Australia that is expected to take at least ten weeks to acquire.
The survey will cover production licences WA-46-L, WA-47-L and WA-48-L in the Wheatstone and Iago gas fields in Commonwealth waters north of Barrow Island.
The 4D project aims to repeat the acquisition of the 3D survey over the same area in 2011–2012, as part of a monitoring programme. The programme is scheduled to occur between mid-December 2022 and mid-April 2023, subject to vessel availability, and is expected to take ~75 days to acquire.
Seismic acquisition will be conducted 24 hours a day. Chevron’s environment plan proposals have been published on the Nopsema website and are open for comment.
