The present invention discloses a diffusion edited pulse technique that allows
information about a fluid to be extracted, comprising: a) obtaining a fluid sample;
b) generating a sequence of magnetic field pulses in the fluid, the sequence comprising
an initial magnetic field pulse, a first portion that follows the initial magnetic
field pulse, and a second portion that follows the first portion; c) detecting
magnetic resonance signals using the second portion of the sequence; d) modifying
the first portion of the sequence, and repeating steps (b) and (c); and e) extracting
information about the fluid by determining relaxation and diffusion characteristics
and their correlation based on the signals detected in steps (c) and (d). Also
disclosed is a logging tool equipped with a processor to implement the diffusion
edited pulse technique.
