The advent of broadband acquisition and processing has delivered a step-change in the resolution of seismic data. In particular, the combination of the BroadSeis™ and BroadSource™ 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.
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:
For even better resolution at the near surface our TopSeis™ solution uses a unique source-over-streamers configuration to deliver vastly increased near surface fold from a split spread with zero offsets.
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.
Reveal intricate velocity details for the clearest images. Harness seismic low frequencies from BroadSeis, StagSeis, seabed and land data.
