Abstract
A method for evaluating a formation fluid includes flowing formation fluid through a flowline in a downhole fluid sampling and evaluation measurement tool deployed in a wellbore and making optical absorption measurements on the flowing formation fluid to generate a plurality of optical density spectra. A spectrum from the plurality of generated spectra is selected using predetermined selection criteria that are based on optical density values at one or more selected wavelengths in the generated spectra. At least one fluid property is estimated from the selected spectrum.
