Abstract:
A method of controlling the quality of processed seismic data, comprising the steps of:(a) selecting a first portion of the seismic data for test processing;(b) processing said selected first portion of the seismic data according to a combination of at least one first processing step to form a first processed data portion;(c) analyzing said first processed data portion to form a measure of the quality of the first processed data portion;(d) controlling a parameter of the processing in the response to the quality measure;(e) processing the seismic data utilizing the parameter which has been controlled in step (d);(f) selecting a second processing step;(g) selecting a second portion of the processed seismic data produced by step (e) for test processing;(h) processing said second portion of the seismic data selected in step (g) according to the second processing step to form a second processed data portion;(i) analyzing said second processed data portion using the quality measure of step (c);(j) controlling a parameter in said second processing step in response to the quality measure from step (i); and(k) processing the seismic data utilizing the parameter which has been controlled in step (j).
