Abstract
A semblance attribute to more reliably detect a seismic discontinuity is provided. The semblance attribute of the center point of a seismic volume is calculated from 3D traces within a spatial and time window. The seismic attribute is dependent, at least in part, on the ratio of the square of the sum of the amplitudes of said traces within the window and the sum of the squared amplitudes of said seismic traces over within the window.
