Abstract
A method for stratigraphic interpretation of a seismic image for determining a sedimentary history of an underground zone having application to petroleum exploration. The seismic reflectors of the image are digitized by means of an applied shape recognition technique. At least one attribute characteristic of the structure of the image in the vicinity of each reflector is calculated for a set of reflectors by means of an image analysis technique. This analysis is based on at least one analysis window whose shape is controlled by the associated reflector. Pertinent reflectors, in the sense of the stratigraphic interpretation, are selected from among this set of reflectors on the basis of this attribute. Finally, the sedimentary history of the underground zone is reconstructed from a stratigraphic interpretation of the reflectors thus selected.
