The combination of BroadSourceTM & BroadSeisTM brings the best broadband source and receiver solutions together in one seamless package, to deliver a ghost-free broadband solution with the widest available bandwidth at 2.5 - 200Hz. This upper frequency is limited only by the sample interval Nyquist and the absorption effect of the earth. The most detailed high-resolution subsurface images are delivered by the resulting sharp wavelets without sidelobes.
The BroadSeis-BroadSource solution
BroadSeis extends the bandwidth to both the low frequencies, by enabling the streamer to be towed deeper, and the high frequencies, by removal of the receiver ghost notch. BroadSource complements the BroadSeis receiver deghosting solution by removing the source ghost notch to extend the spectrum to the sampling interval Nyquist, without compromising the low frequencies.
Glacier flushes and sedimentary infill in old fjords
become visible in data acquired using BroadSeis
with BroadSource. Small features down to 15m
can be resolved
The 6 octaves of signal provided by BroadSource in the shallow section delivers incredible resolution and provides a detailed 3D image of the near surface. It becomes possible to identify sedimentary infill in old glaciation channels and clearly delineate unconformities and geohazards. This makes the data suitable for use as a site survey.
The broad bandwidth achieved using the BroadSeis– BroadSource combination produces wavelets which represent the true formation signature, without the confusion of sidelobe noise. This provides excellent ties with well data.
