The present invention relates to a method of processing seismic image of the subsurface, said seismic image comprising pixels, each pixel having a color value. The method comprises determining two surfaces in the seismic image, the two surfaces extending from one side of the seismic image to an opposite side of the seismic image, the two surfaces being determined based on geological information extracted from well data from at least one well in the subsurface; determining the dip components for pixels of the first surface and for pixels of the second surface; for each current pixel of the seismic image between the two surfaces: determining interpolated dip components based on dip components of the two surfaces; determining an interpolated surface based on at least the interpolated dip components; determining a density value based on a number of intersections of the determined surfaces with a column comprising said current pixel, said intersections being below said pixel in said column; determining a geological-time image, columns of said geological-time image are computed based on the density values of pixels of a corresponding column of the seismic image; and on the color value of pixels of the corresponding column of the seismic image. |
