Training KHAN to recognize:
Oil, Wet, Tight, Shale


Generally not possible to accurately analyze pay from a long depth interval at one time in a conventional top down approach unless make assumptions about constant parameters. Single Archie parameters are not necessarily valid for larger intervals.

KHAN incorporates other petrophysical parameters besides porosity and resistivity as appropriate including composition to encompass lithofacies.
