  • Patent number: 3946356
    Abstract: A synthetic display is provided, in cross-sectional form, of the theoretical strength of seismic reflections. The theoretical strength is computed from calculated inverval-velocity values and known or estimated density values. By comparison of this synthetic reflection-strength display with the observed reflection-strength display, useful conclusions may be drawn about the nature of geological materials and the complex origin of reflections.

  • Patent number: 3931609
    Abstract: The present invention relates to a model, and the making of such model, of subsurface features of the earth, utilizing a plurality of processed seismic sections spaced apart in a manner representing the disposition of the seismic profiles along seismic survey lines from which they came. The technique facilitates the making of interpretive geological judgements, and is of particular utility when direct indications of hydrocarbons exist.
