Next Generation Geophysical Land & Shallow Water Acquisition

The company "NPP "Specgeofizika" participated in the International Summit

The topic of our report was:

Quasi – Continuous Recording and Controlled Sweep Signals Both Increase Productivity of Standard Cabled Acquisition and Image Resolution
(Alexander Zhukov (GDS))

• 3D field experiment comparing Slip Sweep, synchronous simultaneous psuedo-random signals (shuffle) and ISS.
• Looked at ways to enable a cabled system operation to employ ISS style shooting. Continuous recording acquisition is successfully tested.
• Acquisition productivity may be increased with ISS like methods performed by standard vibroseismic crews.
• Final images do not much depend on acquisition methods but mainly on sweep signals employed.
• The Broadsweep signal provides for better resolution and geological object delineation.
• New controlled pseudorandom sweeps potentially can increase both productivity and SNR.
