INPEX submits plans for WA survey

INPEX plans to undertake a 2D seismic survey of two exploration permits in the Browse and Canning Basins offshore Western Australia.

The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) has opened the application for public comment until next month.

INPEX reported that the 2D seismic survey would take place in WA-532-P and WA-533-P and include the acquisition of seismic data in production licence WA-50-L, also within the Browse Basin.

The survey will be undertaken by a seismic survey vessel towing an underwater seismic source and a single streamer behind it.

INPEX highlighted that based on the environmental risk assessments presented in the environment plan (EP), an acceptable window of opportunity was determined to be from November 1 to May 31 in any calendar year that the EP applies.

The duration of the survey is set to take 140 days to acquire the seismic data, with the potential of taking up to 210 days depending on weather.

INPEX further outlined that in the event that the seismic acquisition is unable to commence on November 1, 2021 due to prolonged COVID-19 restrictions, further provision to commence the activity in November 2022 or November 2023 has been allowed for in the resubmission.

“The permit areas are located wholly within Commonwealth waters. At the closest point, the survey activity will be undertaken over 87km west of Broome and 42km offshore from the Dampier Peninsula,” INPEX outlined in its EP.

In addition, the seismic data acquisition within production licence WA-50-L will be undertaken on behalf of INPEX Ichthys.
