CGG announced on Wednesday it has completed its first BroadSeis-BroadSource 3D survey in Australia in July of this year. The ‘Sandman’ deepwater broadband survey on the Northwest Australian shelf was awarded to CGG by oil major Shell and will go a long way towards understanding the area’s oil and gas potential. 

 

The 2,810 km2 3D BroadSeis survey was acquired by seismic vessel Viking Vision towing a 12 x 100 x 6,000 m spread of steerable Sercel Sentinel solid streamers and equipped with BroadSource, CGG’s broadband marine seismic source. 

 

Processing of the data is expected to be completed in the second quarter of 2014.

 

Coupling BroadSource with BoradSeis offers the widest available bandwidth and very low frequencies for deeper and more accurate drilling, CGG claims. This allows the system to  provide high-resolution imaging for the interpretation of subtle hydrocarbon traps and identification of drilling hazards such as shallow gas, making it especially suitable  for the Northwest shelf of Australia. 

 

Jean-Georges Malcor, CEO of CGG, said: “The Sandman survey, acquired successfully using both BroadSeis and BroadSource, is a first globally for Shell and we are confident that it will help unlock the considerable E&P potential of such an important region as the Northwest shelf of Australia.”
