TGS has begun a 1,500km 2D seismic survey north of the Sunrise-Troubadour gas fields and to the west of the Abadi gas field, offshore Indonesia.

The MHI11 survey will complement a seismic survey that was acquired in 2007 and extensive multibeam data.

On completion, the library will include 120,000km of 2D seismic data, 3,500km2 of 3D seismic data, 400,000km of multibeam bathymetric data and 1,200 core samples covering one million square kilometres in Indonesia’s deepwater basins.

M/V Aquila Explorer will secure the seismic data, which is expected to be completed by the end of the fourth quarter of 2011.
