Detailed fracture system analysis lays the foundation for precise structure and stratigraphy description. In this paper several fracture system description methods using seismic data are briefly discussed. Their mutual relation, evolution, advantages and weaknesses are also addressed. The approaches to computing three-generation coherence cubes, to extracting enhancing attributes of discontinuity including dip, azimuth, variance, chaos are summarized. A new graph thinning method adapted from computer vision processing is introduced and illustrated with a real data example. Finally, it is pointed out that the quality of input data is vital to automatic seismic data interpretation comparing to various fracture delineation methods.
