TAGLINE
Interpret NMR T2 distributions: partition BVI/CBVI/FFI porosity, estimate permeability with Coates and SDR models, and QC against conventional porosity.
WHO IT'S FOR
Formation evaluation engineers and petrophysicists interpreting NMR logs for porosity partitioning and permeability estimation.
WHAT IT DOES
Accepts T2 bin amplitudes, applies cutoffs for bound vs free fluid, calculates Coates/Timur/SDR permeability, and builds a depth-log summary with conventional porosity QC. Dedicated crossplot tabs support visual QC of model vs measured data.
