Abstract

A system includes a downhole formation fluid sampling tool and a processor. An optical spectrometer of the downhole formation fluid sampling tool is able to measure an optical characteristic of a formation fluid flowing through the downhole formation fluid sampling tool over a plurality of wavelengths. The optical spectrometer generates optical spectra data indicative of this optical characteristic. The processor is designed to receive the optical spectra data generated by the optical spectrometer and to estimate a formation volume factor of the formation fluid based on the optical spectra data.

First claim

What is claimed is:

1. A system, comprising:
a downhole formation fluid sampling tool configured for operation in a downhole environment;
an optical spectrometer of the downhole formation fluid sampling tool, wherein the optical spectrometer is configured to measure an optical characteristic of a formation fluid flowing through the downhole formation fluid sampling tool over a plurality of wavelengths and configured to generate optical spectra data indicative of the optical char…
