A new method and algorithms for picking reflection events according to their phases and frequencies have been designed and applied to processing synthetic and field CMP gathers. The phase/frequency picking algorithms show high resolution and noise immunity, which is evident in object-oriented time sections along several profiles of the Krapivinskoye oilfield in the Tomsk region. Unlike the conventional processing results, the phase/frequency-based sections of thin-layered reservoirs can resolve weak reflectors and minor faults.
