Downhole fluid properties analysis probe, tool and method

A downhole fluid properties optical analysis probe (1) to analyze at least one property of a multiphase flow mixture (100) flowing in a hydrocarbon well (51) has an elongated cylindrical body shape and comprises an optical tip (5) at one end of the elongated cylindrical body arranged to be in contact with the multiphase flow mixture (100), and an optoelectronics module (11) at another end of the elongated cylindrical body arranged to be separated from the multiphase flow mixture (100) and coupled to the optical tip (5) by an optical fiber bundle. The optoelectronics module (11) comprises at least one light source (13) arranged to emit electromagnetic radiations in a wavelength range such that reflectance occurs when gas (g) is present at the optical tip (5) and fluorescence occurs when oil (o) is present at the optical tip (5), at least one reflectance light detector (14) arranged to be responsive to a reflectance light and to provide a reflectance signal (u1(t)) and at least one fluorescence light detector (15) arranged to be responsive to a fluorescence light and to provide a fluorescence signal (u2(t)). ...
