"Processes to analyze a trace su00ecsmico target and to select traces su00ecsmicos to analyze the contents of ruu00ecdo a trace target storage medium legu00ecvel by computer, and,The processing system su00ecsmico ".A process for analyzing a seismic trace target comprises generally select other traces in the space source - receiver not including traces from the same recording of shot, which contains the trace target.And compare the features selected with the trace target.The process generally includes establishing a distance value indicative of the number of collections of shot to be considered together with the analysis of a trace target.By specifying which features among several recordings of shoot compared with the trace target, based on the distance value, calculating a first value of the amplitude associated with the magnitude of the trace target.To calculate a second value amplitude associated with the amplitudes of the traces of comparison is specified, and comparing the first value of the amplitude to the second value of amplitude.The features of comparison, and the target can be analyzed in different windows of time. The trace target is modified in an appropriate way if it is verified that contains noise.The preferred process may be implemented in a system of seismic processing which is included on a seismic vessel.As the process does not require that all the seismic data are acquired and then classified before analyzed for noise, as is the case with many conventional trace editing techniques,The process of achieving preferred can be implemented in real time or close to real. As such, it is possible to control the quality of data in real time.
