A method for determining properties of a mixture of fluids includes: (a)
acquiring a plurality of nuclear magnetic resonance measurements from the
mixture of fluids, each of the plurality of nuclear magnetic resonance
measurements having a different value in an acquisition parameter for
which at least one relaxation selected from the group consisting of
longitudinal relaxation and transverse relaxation affects magnitudes of
the nuclear magnetic resonance measurements; (b) generating a model of the
mixture of fluids; (c) calculating a synthesized nuclear magnetic data set
based on the model; (d) comparing the synthesized nuclear magnetic data
set with the nuclear magnetic resonance measurements; and (e) adjusting
the model and repeating (c) and (d), if difference between the synthesized
nuclear magnetic data set and the nuclear magnetic measurements is greater
than a minimum.
