Searcher Seismic Pty Ltd (Searcher) proposes to undertake a two-dimensional marine seismic survey (Bilby 2D Survey) in Commonwealth waters of the Offshore Roebuck Basin, Western Australia, commencing in March 2015 for a period of up to four months. The survey will be undertaken in an area of the North West Shelf located approximately 95 km north of Port Hedland and approximately 160 km west/south-west of Broome.
Searcher currently anticipates acquiring approximately 12,290 line km of 2D seismic data within the survey area. A broader operational area of approximately 55,000 km2 will accommodate those vessel manoeuvring and ancillary activities (i.e. additional area for the purpose of in-water equipment deployment, recovery and maintenance etc.) that are required to occur outside of the survey acquisition area.
A phased approach to data acquisition is planned, which will reduce the intensity of data acquisition within the 100 m isobath. Data acquisition has been planned to occur in two phases, separated by a period of 2-3 weeks in April when Bilby 2D Survey activities will cease and the survey vessel will conduct data acquisition elsewhere:
 • Phase 1 of data acquisition to initially focus on areas deeper than 100 m, using a minimum of 4 x 4 km line density grid, followed thereafter by data collection in a 4 x 8 km grid over the held acreage further south, in shallower waters.
 • Phase 2 of data acquisition to focus on ‘infilling’ the line density over the held acreage in the centre of the survey area. Line density during this Phase 2 has been planned to a minimum of 8 x 4 km and a maximum of 8 x 8 km.
