Web1. okt 2016 · The reflectivity coefficient plays a key role in stratigraphic description and stratigraphic attribute inversion. However, reflectivity inversion is still a challenge due to the influence of noise and singularity of de-convolution. With the help of SCS, we construct a finer dictionary. WebThe normal incidence seismic trace is then obtained by the convolution of a seismic wavelet (input pulse) with the reflectivity function. The amplitude of each spike on the reflectivity function is determined by the value of the calculated reflection and …
