  • 河北体彩十一选五:Least-Squares Migration

    后一万能码 2期内中 www.qgqx.net Least-Squares Migration provides images with better balanced illumination, improved signal-to-noise ratio, reduced migration artifacts and more interpretable seismic amplitudes. Implementation of a Least-Squares Q-PSDM sequence corrects for absorption and related illumination effects, mitigating artifacts and noise.

    We have successfully applied Least-Squares Migration to datasets from all over the world, including areas of complex geology such as subsalt in the Gulf of Mexico. Least-Squares Migration also brings benefits to challenging time-lapse projects, especially for highly non-repeatable vintages or prospects with weak 4D signal.

    Delivering superior
    imaging

    On this BroadSeis dataset from our Cornerstone survey in UK Central North Sea, Least-Squares Q-PSDM (bottom image) provides a higher resolution image, along with improved illumination balance, reduced migration swing noise and better event continuity when compared to conventional imaging (top image).
