Welcome to Petroleum Geology Forums

Greetings -
I have magnetic resonance imaging (MRI) .las files from Schlumberger. These files contain (Combinable Magnetic Resonance) CMR data e.g.

CMFF .CFCF :CMR Free Fluid {F13.4}
CMRP_3MS.CFCF :CMR 3ms Porosity {F13.4}
TCMR .CFCF :Total CMR Porosity {F13.4}

I was hoping to use the NMR Interpretation module in IP to out put curve of e.g. nmr_effective porosity.
However, this requires an input T2_array distribution base curve; which does not come with the CMR data.

My question is: do i have to waste time in calculating nmr effective porosity when i already have the CMR 3ms Porosity? (same applies for the other curve)

Just in case i need to create and display a T2_array distribution base curve, how do i do that in IP?

You don't need to load the T2_array distribution curve to compute NMR_effective_porosity.
You can use the following equation:

NMR_effective_porosity = TCMR - CMRP_3MS

This should be similar to the petrophysical effective porosity.
Regarding the question on how to load T2_array_distribution curve into IP, I do not have the answer as I have never loaded one yet.
