Inpex to start seismic survey off West Australia
The Australian offshore regulator National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) has granted Japan's Inpex approval to undertake a 2D seismic survey of exploration permits WA-532-P and WA-533-P in the Browse and offshore Canning basins, the regulator said.
The 2D seismic survey will also include the acquisition of seismic data in production licence WA-50-L, also within the Browse basin. The permit areas are located wholly within Commonwealth waters.

At the closest point, the survey activity will be undertaken over 87 km west of Broome and 42 km offshore from the Dampier Peninsula. Seismic data acquisition will mainly take place in water depths between approximately 50 m and 600 m below mean sea level.
However, some seismic data acquisition may occur in shallower areas located at Lynher Bank in the southern part of WA-532-P where the shallowest water depth is about 30 m, and east of WA-533-P where the shallowest water depth is approximately 37 m, NOPSEMA said.
Inpex intends to acquire the survey between November 2021 and May 2022, with contingency to acquire between November 2022 and May 2023, and November 2023 to December 2023 if the earlier date is not achieved, the regulator said. The survey is scheduled to take 140 days.
