Patent ID: 7450468

Claim:
A computer-implemented method for interactively determining optimum deghosting parameter values for suppressing ghost reflections in seismic data obtained from hydrophone/geophone receiver locations, comprising: generating a plurality of energy traces, each of the plurality of energy traces representing a measure of the effectiveness of a set of trial deghosting parameter values for the hydrophone/geophone receiver locations, wherein the set of trial deghosting parameter values comprise a range of numerical constants and at least one increment, wherein the range comprises a minimum deghosting parameter value and a maximum deghosting parameter value, wherein, if neither the minimum deghosting parameter value nor the maximum deghosting parameter value is a multiple of the increment, then adjusting at least one of the minimum and maximum deghosting parameter values so that the at least one of the minimum and maximum deghosting parameter values is a multiple of the increment; displaying the plurality of energy traces; receiving an input of interactively picked deghosting parameter values based on a visual inspection of the displayed plurality of energy traces; displaying the picked deghosting parameter values; and receiving an input for interactively editing and smoothing the displayed picked deghosting parameter values based on a visual inspection of the displayed picked deghosting parameter values to obtain the optimum deghosting parameter values, wherein smoothing the picked deghosting parameter values comprises removing erratic variations in the displayed picked deghosting parameter values which are caused by noise which and are not representative of actual variations in a water bottom comprising the hydrophone/geophone receiver locations and wherein the optimum deghosting parameter values comprise optimum scalar values for each of the hydrophone/geophone receiver locations.
