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.
Claims39
A method of determining a refractive index of oil comprising:
- generating an incident beam, incident on a conductive material having one or more channels, and at an angle of incidence to the conductive material, between the conductive material and an oil material;
- separating the oil material, using the one or more channels, into separate phases;
- monitoring the power of a reflected beam;
- determining a refractive index of the separate phases of the oil material using at least the power of the reflected beam;
- and
- determining one or more other thermophysical values.
An apparatus for determining a refractive index of an oil material comprising:
- a light source for generating an incident beam;
- an incident beam refractor;
- 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, wherein the oil material receptacle includes one or more channels.
A downhole tool adapted for determining a refractive index of an oil material in an oil-bearing portion of a formation, the downhole tool comprising:
- a tool string configured to lower a housing into a wellbore disposed in the formation to a depth where the downhole tool interfaces with the oil-bearing portion;
- and
- an analytical tool, coupled to the housing, the analytical tool including:
- a light source for generating an incident beam;
- an incident beam refractor;
- and
- a conductive material, the conductive material including one or more channels;
- 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.
