  • Automatic gain control for seismic data
    Patent number: 4636993
    Abstract: An improved apparatus and method for calculating automatic gain correction to be applied to seismic samples is disclosed which features apparatus and method for calculation of the average absolute value of a window of samples in the vicinity of the sample being processed, the calculation being performed a first time with the window shifted toward a first side of the sample and a second time with the window shifted toward a second side of the sample, and selecting for use in gain correction the minimum of the two calculated average absolute values, such that high amplitude samples in the vicinity of relatively low amplitude events is precluded from causing unrealistic shadowing around such events.
