  • Method for creating a gain function for seismic data and method for processing seismic data
    Patent number: 5642327
    Abstract: Disclosed is a method for creating a gain function for seismic data and to processing methods for utilizing such a gain function. The method of creating the gain function generally includes representing the seismic data as a plot of the logarithm of amplitude versus time. Various order polynomial functions are subsequently fitted to the plotted seismic data. The best fitting polynomial is then selected from these various order polynomials, the inverse of which is the gain function. This gain function can be utilized in a seismic processing method.
