PCT No. PCT/GB96/01964 Sec. 371 Date Feb. 24, 1998 Sec. 102(e) Date Feb. 24, 1998 PCT Filed Aug. 12, 1996 PCT Pub. No. WO97/08570 PCT Pub. Date Mar. 6, 1997A technique is provided for controlling the quality of processed seismic data without requiring subjective intervention. Seismic data, for instance acquired by land or marine techniques, are supplied as input (1) and a portion for testing is selected (2). First and second combinations of seismic data processing steps are selected (3 and 6). The selected data portion is processed (4 and 7) using these combinations and the thus-processed portions are analyzed to calculate the attributes thereof (5 and 8). These measures are compared (9) and the combination of processing steps giving the better attributes is then used to process the input seismic data (10 or 11).
