Increase Resolution

With Broadband Marine Acquisition for Geohazard Identification

The advent of broadband acquisition and processing has delivered a step-change in the resolution of seismic data. In particular, the combination of the BroadSeisTM and BroadSourceTM solutions removes both the source and receiver ghosts to deliver in excess of 6 octaves of signal, with exceptional low-noise low frequencies and high frequencies limited only by the recording sample interval and the absorption of the earth. When this technology is combined with Full Source Characterization and 3D designature and deghosting, unparalleled resolution is achieved.

Resolution-3D

The exceptional resolution delivered by this combination provides the optimum resolution available and enables BroadSource-BroadSeis surveys to be used as site surveys and for geohazard identification:

  • Wavelets with minimal sidelobes for the highest-resolution ghost-free images
  • High frequencies limited only by recording sample interval and the Earth’s absorption
  • Broadest bandwidth in the industry, with best low-frequency S/N ratio: 2.5 – 200Hz, over 6 octaves in the shallow section
  • Optimum 3D spatial resolution from flip-flop dual-source arrays

Intelligent Interpolation

When data is intelligently interpolated using a 5D Fourier anti-leakage algorithm to a 6.25 x 9.375m, gas pockets of 20m and iceberg scrapes as small as 15m can be identified.
