    摘要: Method for building a seismic imaging velocity model, particularly at the boundary of a geo-body, and to perform imaging, by taking into account the elastic reflection and scattering information in the seismic data. More illumination of the base and flanks (or in general, the boundary) of the geo-body is provided from (a) inside of the geo-body (502), with elastically converted waves at the geo-body boundary used (via elastic RTM flooding); and (b) from outside the geo-body (503), by utilizing prism waves with elastic RTM to handle the phase correctly in the model building step. The increased illumination and correct elastic phase are used for geo-body boundary determination. Elastic RTM is then applied (505), along with the elastically derived imaging velocity model, to maximize the use of elastic energy in the imaging step, and to obtain the correct image with the correct phase.

    摘要: Embodiments of methods of creating and interpreting animated mosaics of multiple seismic surveys are disclosed herein. Volumes from individual seismic surveys may be flattened in each seismic cube. Animations/movies may then be produced by capturing a series of z-slice movie frames through each of the flattened volumes. The individual sets of movie frames are geo-referenced to a basemap image of well locations using appropriate composition software. Where overlap exists between surveys, the surveys are prioritized and lower priority volumes are masked by higher priority volumes. This technique provides a matched, unbroken image across overlapping volumes at each stratigraphic layer. As the movie or animation plays, a moving arrow pointer shows the vertical position of the current movie frame on a stratigraphic section consisting of a seismic reference section that is optionally labelled with suitable regional sequence names and other stratigraphic zonation data.

    摘要: A method of determining a search expression describing a feature of interest in a set of data points distributed throughout a geological object is provided. Each data point contains a value for a geological attribute at that point. The search expression has a plurality of entries. The method including the steps of: (i) displaying the geological object using display codings corresponding to value subranges for the geological attribute such that all data points which have values for the geological attribute falling within a given value subrange are displayed with the same coding; (ii) selecting a plurality of data points of the feature of interest; and (iii) allocating value characters to entries of the search expression, the value characters corresponding to the value subranges for the geological attribute of the selected data points.
