    distribution, offset distribution and azimuth distribution in a bin have direct
    effects on geometry attributes in 3D seismic survey design. The authors
    introduce in this paper a uniformity quantitative analysis method for offset
    distribution by average value, square deviation and weighting factor. The paper
    analyzes effects on offset distribution uniformity of different 3D geometry
    parameters by the proposed uniformity quantitative analysis method. Furthermore,
    the paper analyses effects on seismic stack amplitude or frequency uniformity
    of different 3D geometry parameters by the seismic wave modeling. The results
    show that offset distribution uniformity is in good agreement with seismic
    stack amplitude or frequency uniformity. Therefore, it improved method can be
    considered as a useful tool for analyzing and evaluating 3D geometry attribute
    uniformity.
