B008 Air–Leak Detection Using Frequency Domain Deconvolution A.J. Day* (PGS Geophysical AS) S. Hegna (PGS Geophysical AS) G. Parkes (PGS Geophysical AS) & N. Turnbull (PGS Geophysical AS) SUMMARY Air-leaks in marine seismic sources are known to have a detrimental effect on the source signature and they are therefore not tolerated during production. If an air-leak is detected acquisition must cease whilst the fault is rectified leading to costly “downtime”. A method for detecting air-leaks has been developed that makes use of signatures recorded by near-field hydrophones positioned near each gun in an array. The complex spectrum of each trace
