Z-99 Proper time-referencing for prestack Q estimation and compensation P276 Summary 1 GANYUAN XIA BP E&P Technology Houston TX 77079 USA When applying attenuation compensation for prestack marine data the traveltime spent in the water layer should be removed from the total traveltime because water practically does not attenuate acoustic waves. Current industry practices use either vertical water bottom time or offset water bottom time as the reference time. Both worked for certain water depths and targets but failed in general to remove the water layer accurately. The relative timing error of improper timing referencing can be as large as
