Abstract
The processing comprises an analysis of a seismic image to estimate seismic horizons in an area of the subsurface and the calculation of an accumulation value associated with each pixel of the seismic image by accumulation along a set of estimated seismic horizons to form a synthesized image composed of accumulation values. This synthesized image is transformed to obtain a seismic representation in which signed amplitudes are allocated to the pixels of the synthesized image. The transformation may comprise a combination with the original seismic image or else a convolution with a wavelet or another convolution kernel.
