More Information
Summary:A method for analyzing unconventional rock samples (202) using nuclear magnetic resonance (NMR), comprising tracking fluid change in the rock sample (202) over a time period, calculating transverse relaxation time (T2) spectra and generating fluid distribution profiles by the computer processor (704) based on NMR imaging, where the fluid distribution profiles represent a movement of the fluid, and quantifying fracture volume by the computer processor (704). L'invention concerne un procédé d'analyse d'échantillons de roche non conventionnelle (202) à l'aide de la résonance magnétique nucléaire (RMN), comprenant le suivi d'un changement de fluide dans l'échantillon de roche (202) sur une période, le calcul de spectres de temps de relaxation transversale (T2) et la génération de profils de distribution de fluide par le processeur informatique (704) sur la base d'une imagerie RMN, les profils de distribution de fluide représentant un mouvement du fluide, et la quantification du volume de fracture par le processeur informatique (704).
