The marine seismic survey proposed is a conventional 2D survey similar to most others conducted in Australian waters in terms of technical methods and procedures. The survey will be conducted using a purpose built seismic vessel.
Data acquisition will occur along approximately 10,000 km of predetermined sail lines, spaced ~25 km apart within the survey area, covering approximately 168,000 km2. At the closest point the survey polygon is located ~100 km from Exmouth, ~90 km from Carnarvon and 25 km from Geraldton. The water depths in the survey area are in the range of ~40 to >1,000 m with the shallowest water depths located along the eastern boundaries of the survey area.
The seismic vessel will not operate within 20 km of land across the entire survey area.
Data acquisition will take approximately four months to complete. The preferred commencement date for the survey is Q4 2014 with completion occurring before the end of Q1 2015. However, due to current restrictions on vessel availability it may not be possible to acquire data during this period and therefore the activity may occur at any time from Q4 2014 to Q4 2015. The survey vessel may return to port during the survey for the purpose of refuelling or crew changes, although refuelling and crew changes may also occur at sea.
