Claim:
1. A method of analyzing a composition of a hydrocarbon phase of a hydrocarbon-containing fluid containing a plurality of hydrocarbons of different chain lengths, comprising: using a nuclear magnetic resonance (NMR) tool to conduct a NMR relaxation measurement, a diffusion measurement, or both on the hydrocarbon-containing fluid to obtain NMR data; using a non-NMR tool to conduct an additional measurement of a reference fluid containing hydrocarbons to obtain non-NMR data wherein the additional measurement comprises gas chromatography, optical spectroscopy, or both; and using the NMR data and the non-NMR data in an inversion process to determine an indication of the composition of the hydrocarbon phase of the hydrocarbon-containing fluid.
