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.

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 material, between the conductive material and an oil material;
- monitoring the power of a reflected beam;
- and
- determining a refractive index of the oil material using at least the power of the reflected beam.
An apparatus for determining a refractive index of an oil material comprising:
- a light source for generating an incident beam;
- an optically permissive material, for refracting the incident beam;
- a conductive material;
- a detector configured for sensing characteristics of a reflected beam;
- and
- an oil material receptacle configured for co-operatively disposing the oil material relative to the conductive material, the oil material interacting with the conductive material such that when the incident beam interacts with the conductive material under resonant conditions, the detector senses an attenuation in the power of the reflected beam.
A downhole tool adapted for determining a refractive index of an oil material in an oil layer, the downhole tool comprising:
- a descending device adapted for lowering a housing into a hole to a depth where the downhole tool interfaces with an oil layer;
- and
- an analytical tool, coupled to the housing, the analytical tool including:
- a light source for generating an incident beam;
- an optically permissive material, for refracting the incident beam;
- a conductive material;
- and
- a detector configured for sensing characteristics of a reflected beam;
- wherein the oil material is co-operatively disposed relative to the conductive material and the oil material interacts with the conductive material such that when the incident beam interacts with the conductive material under resonant conditions, the detector senses an attenuation in the power of the reflected beam.
