[Users] phase spectrum in spectral analysis

Dear users,

I have been lately testing the spectral decomposition tool in OD to
define and characterise various geobodies. 

Although good results in term of vertical thickness and lateral extent
assessment are obtained by analysing amplitude maps at given
frequencies, it is often mentioned in the literature the use of spectral
phase maps (additionally to spectral amplitude maps) to further detect
lateral discontinuities.

 

I am not quite sure if 1) OD has this option, and if not, (as I am just
a geologist) if a similar result could be achieved by 2) computing an
instantaneous attribute (ie phase) with the Spectral Decomp attribute
(at a given frequency) as an input.

 

Cheers,

 

Laurent
