ABSTRACT:
An apparatus for estimating a property of a fluid downhole, is provided an includes: an optical fiber that receives light emitted from a light source and including an unclad portion adapted for contacting the fluid; a photodetector for receiving optical signals from the portion; and a spectrometer for obtaining an evanescent spectrum of the fluid from the portion. A method and a system are included.
