Shape-based metrics in reservoir characterization

摘要

Method for the segmentation and classification of seismic or other geophysical data. Curves or surfaces are identified in the geophysical data (10), then pairs of the curves or surfaces (12) are matched up according to a selected measure of shape similarity (13) such as the Hausdorff distance between members of a pair. The matched curves or surfaces (15) are used to define geobodies or faults in the geophysical data volume (16). The same inventive concept may also be used to warp/align (register) two different data volumes (72).

1. A computer-implemented method for segmenting a 2-D or 3-D volume of geophysical data representing a subsurface region for interpretation of physical structure in the subsurface region, said method comprising:
identifying curves or surfaces in the geophysical data, using a computer to match up pairs of the curves or surfaces according to a selected measure of shape similarity, using the matched-up curves or surfaces to define geobodies or faults in the geophysical data volume, interpreting the geobodies or faults to indicate physical structure of the subsurface region, and using the interpreted physical structure to explore for or produce hydrocarbons.
