LAS VEGAS – WesternGeco featured during the SEG annual meeting in Las Vegas a look at the results of its IsoMetrix marine seismic survey done with the cooperation of Statoil in the North Sea.
The IsoMetrix technology measures the full up-going and down-going notchless seismic wavefield sampled at a 6.25 m by 6.25 m (20.5 ft by 20.5 ft) point-receiver surface grid. This sampling in both crossline and inline directions makes the data suitable for a variety of interpretation and modeling applications, said WesternGeco.
This ability to measure the wavefield is the result of a new type of towed streamer called Nessie. It combines hydrophones with point receiver, and multi-component, microelectromechanical (MEMS) accelerometers.
