PGS wins offshore wind characterisation project PGS has won a large offshore windfarm site characterisation contract in the US from a ‘leading renewable energy company’. PGS will use the vessel Sanco Swift, which is rigged as an offshore wind site characterisation vessel. Mobilisation is scheduled for August 2023 and acquisi-

tion is expected to complete in February 2024, with total project duration of approx. 180 days. The company’s second offshore wind site characterisation project will be acquired with PGS’ ultra-high-resolution 3D (UHR3D) P-Cable. ‘The UHR3D system provides significantly more detailed subsurface data for shallower targets compared to traditional seismic acquisition systems,’ said PGS. Berit Osnes, executive vice-president new energy of PGS, said: ‘Our geophysical approach to map and understand the shallow subsurface layers with our UHR3D system is significantly more efficient than conventional solutions. Energy companies acknowledge the value of shorter lead time for accessing high-quality data.’

Chevron plans 4D survey offshore Australia
200 Day Recording Down to 3,450m
Chevron is planning a 4D marine seismic survey (MSS) over 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, Western Australia. The 4D MSS aims to repeat the acquisition of the 3D MSS conducted over the same area in 2011-2012, as part of a monitoring program. The 4D MSS is scheduled to occur between mid-December 2023 and mid-April 2024, subject to vessel availability, and is expected to take ~75 days to acquire. While the seismic and support vessels may mobilise to the operational area during December 2023, seismic acquisition will not commence before 1 January, 2024. Seismic acquisition will be conducted 24 hours a day. The Full Power Zone for the 4D MSS defines the area where the seismic source will be discharged at full power. The Full
