Abstract
The charting method consists in realising a recordings acquisition, constituting on the basis of the recorded seismic traces, a 3D seismic block (X, Y, T) sampled in elementary cells (C.sub.ijk), such that each elementary cell contains a sample (k) of a central seismic trace (TR.sub.ij), calculating for each elementary cell (C.sub.ijk) of the seismic block, the energy thereof, and fixing an energy threshold beyond which the presence Tk of anomaly zones is considered probable, selecting cells of the block which have energy equal or superior to the said threshold, coding the selected cells, such that all the cells belonging to a same contiguously selected cell set have the same code and the selected cells belonging to distinct contiguously selected cell sets have different codes, and effecting an XY projection of the coded cell block.
