ABSTRACT:
Apparatus and method are disclosed for use with a horizon picking method for 3D seismic data. Variables such as picking method, whether simple or iterative, score required of an iterative method and .DELTA.T between target wavelets and seed wavelet are input into the computer. During the picking process, parameters as to the number of successful picks and the number of failed picks because of the method of picking and because of failed picks due to the score not being achieved in the iterative method and because of failed picks due to the difference in time between the target wavelet and the seed wavelet being greater than the .DELTA.T variable are recorded. The number of score failures to pick a target wavelet from a seed wavelet is recorded where the score achieved is less than the input score. A characteristic of such number of score failures, such as the percentage of score failures to the total number of picking tries, is displayed on a CRT screen.
