The geophysical company TGS-NOPEC Geophysical Company Pty Ltd (TGS) proposes to acquire multi- client (MC) two-dimensional (2D) and three-dimensional (3D) marine seismic surveys (MSS) within the Canning and Northern Carnarvon Basins in the North-west Marine Region (NWMR) offshore from Western Australia (WA).
The Canning-Northern Carnarvon MC MSS EP is expected to have a duration of up to 18 months. The timing of commencement and duration of individual surveys to be acquired within the operational area has not yet been determined, but it is anticipated that the first survey shall commence in Q2 2015. The commencement of each survey will be dependent on fair sea state conditions suitable for marine seismic acquisition, the availability of a survey vessel(s) for conducting the survey, client data schedule requirements, fauna migration timing and granting of approvals from the appropriate government bodies. The operating pressure for the seismic energy source for both 2D and 3D will be approximately 2,000 psi.
The Canning-Northern Carnarvon MC MSS operational area lies entirely in Commonwealth waters within the NWMR and encompasses an area of ~320,300 km². Water depths range from ~30 m to ~5,700 m, with the deepest water depths located along the north-western boundary of the operational area, and the shallowest water depths located along the eastern boundary. At its closest point, the operational area is ~7 km north of Bedout Island, ~25 km southwest of Imperieuse Island, ~55 km north of Port Hedland and ~65 km northeast from Legendre Island. An exclusion zone has been placed around the Glomar Shoal that ensures seismic acquisition shall only occur in waters 1 km beyond the 50 m contour line.
