  • 重庆时时分析手机软件:BroadSeis with BroadSource

    后一万能码 2期内中 www.qgqx.net 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.

    Benefits

    The BroadSeis-BroadSource solution

    • provides over 6 octaves of signal in the shallow section (from 2.5Hz to 200 Hz),
    • delivers ultra-high resolution of near surface detail and can be used for site surveys and shallow hazard identification
    • has all the advantages of a conventional source - stable, reliable, good directivity and available in flip-flop mode.
    • is available on all CGG vessels, with over 75,000km2 of BroadSource data so far acquired

    Ghost-free broadband data

    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.

    glacial fill

    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

    Shallow Hazard Identification

    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.

    Accurate well-ties

    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.
