Claim Text:
1. A nuclear magnetic resonance (NMR) measurement system comprising: a sensor assembly comprising a sample holder having a body defining an interior cavity for receiving a fluid sample, a frame member disposed in the interior cavity of the sample holder, an antenna coil disposed in the interior cavity about the frame member, an inlet that allows the fluid sample to enter the interior cavity, an outlet that allows for the fluid sample to be flushed from the interior cavity, and a magnet assembly having a central bore in which the sample holder is disposed; and pulse sequencer circuitry that supplies signals to the antenna coil; wherein, when the interior cavity of the sample holder is filled with the fluid sample, the antenna coil and the frame member are at least partially submerged in the fluid sample, and the antenna coil is configured to obtain NMR measurements of the fluid sample in response to the signals wherein the NMR measurements comprise at least one of a longitudinal relaxation time distribution (T wherein the model-independent mapping function is determined using a database comprising NMR and fluid property measurements obtained on a plurality of reservoir fluids at a plurality of temperatures and pressures.
