Re: Splitting Zone in Interactive Petrophysics
Zonation is done when there are changes in petrophysical properties or geological formations. It is very rare that the clay parameters remain the same throughout the whole well from top to bottom, especially for long intervals. Therefore, if you do not zone the clay parameters properly, like GRmin and GRmax for example, you will end up with wrong Vclay values. Likewise, if the geological formations change, e.g. different sand groups or different depositional environment, the clay parameters should also be zoned to reflect these changes.
Even if a well is dry and does not contain any hydrocarbon, you should do zonation to calculate the petrophysical properties correctly.
