Title: IMAGE ENHANCEMENT USING SEISMIC PARTITION IMAGES
Abstract:
A method for generating an image of a subterranean formation includes receiving seismic data that was collected from seismic waves that propagated in the subterranean formation. Partition images are generated using the seismic data. A geological model of the subterranean formation is generated. Dip fields in the partition images are determined. A target dip field in the geological model is determined. A degree of correlation between the respective dip fields and the target dip field is determined. Weights are assigned to the partition images based upon the degrees of correlation to produce weighted partition images. The image of the subterranean formation is generated by stacking the weighted partition images.
