ABSTRACT:
A method in real time control systems for seismic interference to indicate an acceptable level of interference in relation to the amplitude, angle of incidence, and frequency of a seismic reflection signal, and to remove such interference loaded signals during seismic surveys, comprises steps to determine lower threshold values of coverage, identify interference and amplitude anomaly in the recorded signal of reflection, estimate the expected value of amplitude characteristic of the signal on the basis of recorded amplitude characteristics of recorded signals from one or a plurality of preceding series of survey, mark time windows in which interference and/or amplitude anomaly are identified, generate a table of the number of times a certain time window was marked in the series of recordings of the same point of reflection, assign limits on the number of interference events to various marked time windows, and remove from the recordings those time windows wherein the number of interference events exceeds the limit.
