Abstract

This study presents an innovative approach for seismic image enhancement using multi-parameter CIGs. During the imaging, summation-free CIGs are generated and analyzed as constant depth slices at every image location. The signal’s coherency is measured by semblance coefficient for different dip-angles across these depth slices in order to detect the specular directions of the model. The enhanced migration image is achieved by partial stacking of the gathers along these directions only. The ability to analyze the structural parameters of each image point allows us to better handle cases of complicated wave propagation and to improve the image quality at poorly illuminated areas or near complex structural geometry. The proposed method and its practical benefits are demonstrated for synthetic and real datasets.
