A method is disclosed for interpretation of multi-dimensional nuclear
magnetic resonance data taken on a sample of an earth formation.
Specifically, a set of NMR data is acquired for a fluid sample located
either in a borehole or in a laboratory environment. From the set of NMR
data, a multi-dimensional distribution is calculated using a mathematical
inversion that is independent of prior knowledge of fluid sample
properties. The multi-dimensional distribution is graphically displayed
on a multi-dimensional map. Each fluid instance or artifact visible on
the graph is identified as representing a probable existence of a
detected fluid. One or more quantitative formation evaluation answers for
one or more fluid instances is computed based on the multi-dimensional
distribution associated with the respective fluid instance.
