METHOD AND SYSTEM FOR DETECTING A GEOLOGICAL OBJECT IN A SEISMIC 3D IMAGE BY USING IMAGE SEGMENTATION

Abstract: a computer implemented method provides for detecting a geological object in a geological formation by processing a seismic 3d image, said seismic 3d image comprising a plurality of pixels representing seismic measurements performed on the geological formation. the method includes computing, based on the seismic 3d image, a geological-time (gt) isochronous surface of the geological formation, wherein the gt isochronous surface corresponds to the coordinates of pixels of the seismic 3d image which represent portions of the geological formation considered to have a same geological age, computing a seismic attribute 2d image representing at least one seismic attribute of the geological formation on the gt isochronous surface, and detecting, by image segmentation, pixels of the seismic attribute 2d image which represent the geological object.
