Combination of minimum-maximum (m-m) attribute and zero-INTENS-difference (z-i-d) attribute for estimating below-tuning layer thickness : A new technique proposal

Abstract- This paper demonstrates a new alternative way in estimating layer thickness below the tuning thickness of a poststacked,zero-phase seismic. Preliminary reflectivity map is built by band-pass filtering the amplitude map of the seismic. The filter removes the non minimum and or non maximum...

Preliminary reflectivity map is built by band-pass filtering the amplitude map of the seismic.

The unresolved thickness below the tuning thickness is then corrected by zero-INTENS-difference (z-i-d) attribute, a form of spectral analysis of the seismic trace. z-i-d attribute is zero difference of Integrated Energy Spectra (INTENS) between a synthetic seismic and its true seismic.
