Optimum Decon
Optimum Deconvolution (OPTDCN) determines post-stack optimum deconvolution operators that would enhance the signal amplitudes by "spiking" them within a specified bandwidth.  This module measures the signal-to-noise ratio in defined windows of data volumes as a function of frequency.  It then designs an optimal filter such that all usable bandwidth is extracted.

Example
Gulf Coast data shows increased bandwidth in the second window. Post-stack process offers better interpretability of subtle faulting, tightly bedded formations, and sand packages of producing fields.
