Bright spot is one of the pattern classes in a seismic section and the indicators of gas hydrocarbon accumulation. In the past, detection of bright spots depended primarily upon visual examination and the experience of a geophysicist. It is the authors contention that bright spot detection could be made more confidently by computer-aided analysis. This study concerns with two computer-aided methods. One is the decision-theoretic pattern recognition, the other is the syntactic or structural patterns recognition. Using these two methods, a seismogram is classified into two classes, i.e., bright spot and non-bright spot.
