Description
Generating seismic instantaneous attributes
Seismic attributes gives valuable information in the reflection seismology as well as reservoir studies. The main seismic attributes in the reflection seismology are
1.Amplitude
2.Frequency
3.Phase
Besides these attributes there are many attributes that can be generated using the seismic data or for that matter seismic trace and analyze their properties which will be helpful in understanding the physical properties of the wave propagation, attenuation etc. These attribute information is useful in better understanding of the structural and stratigraphic interpretation of the geological events.
Seismic Instantaneous Attributes are computed sample by sample and indicate continuous change of attributes along the time and space axis.

Input gather
Parameters
Time window
Provide the time window to measure the required seismic attributes within the defined time window
Instantaneous attributes types
Envelop:Which is helpful in identifying the discontinuities like faults, lithology etc.
Phase ARG:Phase shows the continuity of the events. It is independent of amplitude
Phase_Unwrap_ARG
Frequency:Instantaneous frequency represents the mean amplitude of the wavelet and also it is the derivative of the phase.
Frequency_Deviation:
Bandwidth:
NormAMP:
FREQW:
THIN:
FENV:
SENV:
Q:Q is known as Quality factor where the wavelet travels beneath the subsurface underwent energy loss. In other words higher frequency loss and dispersion. To compensate the loss we measure the Q value and apply for both Phase and Amplitude.
