Abstract
The velocity analysis by using the spectra has shown better results than the velocity function technique, besides that the former is characterized by higher stacking velocity values. The stacking velocities obtained from the two techniques were evaluated in relation to the average velocities from wells located on the seismic lines. The comparison shows that all the velocity function values are much lower than the average velocities. The stacking velocities by using velocity spectra vary slightly between lower and higher values than the average velocities.
The raw final stack using velocity spectra shows better improvement than the final stack using velocity functions; for example, in the recognition of faults.
