Abstract:
A method for efficiently processing a seismic 2-D or 3-D measurement data set comprising a large number of seismic traces, wherein each data set comprises a series of data points having amplitude values, the method comprising the steps of:a) determining a threshold value for the series of data points; b) converting the set of measured data into a set of binary data comprising a plurality of binarized data points in which each data point is assigned either a number â€œ0â€  if an amplitude value is lower than said threshold value or a number â€œ1â€  if an amplitude value is equal or greater than said threshold value; c) forming for each binarized data point a cell of a predetermined cell size from said plurality of binarized data points wherein each cell defines an environment including a central data point; and d) conducting a similarity analysis on each cell wherein each of said cells has said central data point and said central data point is assigned a similarity value reflecting the degree of similarity of binary data values in its respective cell wherein said similarity value corresponds to the quantity of the greatest number of the data points in the cell with the same binary value.
