Abstract
Systems and methods for classifying oil materials. A method of determining a refractive index of oil comprising: generating an incident beam, incident on a conductive material and at an angle of incidence to the conductive layer, between the conductive material and an oil material; monitoring the power of a reflected beam; and determining an angle of resonance by changing the angle of incidence of the incident beam; determining a refractive index of the oil material using at least the power of the reflected beam. Systems and methods may be provided for on-surface testing or downhole in situ testing.
