Wavefield Mobilizes Bergen Surveyor for First Job

Wavefield Geophysical AS has completed an upgrade of its Bergen Surveyor vessel in preparation for the company's first survey: a new multi-client 2D program in the Central Nordkapp basin offshore Norway.

Now fully mobilized, the Bergen Surveyor is equipped with solid Teledyne SDS-55 streamer and dual Bolt Annular Port Gun source arrays and will acquire the regional 2D survey for sister company InSeis AS. The upgrade will also enable the vessel to acquire 3D data with dual streamers and a dual-source configuration.

Originally converted in 1997, this latest upgrade to the Bergen Surveyor makes it an extremely flexible unit, said Wavefield. The company explained that the vessel is rigged for the long offset 2D, developmen,t 3D/4D, and source vessel markets. It added that the use of the Bolt APG source in particular gives it a very compact, efficient, and high-output energy source that can be designed to meet the varying requirements for source performance in different regions world-wide and also to match as close as possible the output from other sources in multi-azimuth acquisition and legacy 4D surveys.
