QC

Prime contains full list of all that necessary for field QC: handle tools and interactive applications for parameters computation and displaying.

Seismic trace attributes:

  • the instantaneous amplitude,
  • the instantaneous phase,
  • the instantaneous frequency,
  • the instantaneous weight average frequency.

Wave field parameters:

  • the weight average frequency;
  • dominant frequency;
  • the energy of trace;
  • the ratio of trace energies which are related to the different horizons;
  • the signal to noise ratio, which is estimated through the cross-correlation function;
  • the logarithm of amplitude, cepstrum decomposition, which is estimated through the cross-correlation function;
  • the RMS amplitude in sliding window;
  • the coherency.
