Abstract:
Methods and related apparatuses of a downhole micro nuclear magnetic resonance (NMR) device having a resonant tuning (LC) circuit for use in a formation for collecting NMR signals from a fluid in the formation while under downhole pressures and temperatures. The downhole micro NMR device includes: a micro tube for the flowing fluid to flow therethrough; at least one magnet disposed about the micro tube; and at least one micro RF coil structured and arranged approximate to the micro tube and tuned to a Larmor frequency corresponding to a applied magnetic field from the at least one magnet.
