Faults Extraction from seismic cube Using a double Hough transform

in: 25th gOcad Meeting, ASGA

Abstract

Many different seismic attributes have been proposed so far in the literature to “mark” the presence of faults in a seismic cube. From these attributes, the challenge is now to extract, automatically, a fault network where each fault is individualized. For this purpose, we use the Hough transform method in a two steps algorithm. The basic idea of this algorithm is that the intersection of a fault by a series of vertical planes is (approximately) a family of straight-lines. Each of these straight-lines is transformed into a point in a parametric space thanks to a first Hough transform. For each fault, the set of points so obtained constitutes (approximately) a new straight-line in the parametric space which is then transformed into a point of a second parametric space thanks to a new Hough transform. This paper presents the Hough transform adapted to faults extraction and show some real cases applications.
