Fiber optic refractometer |
| abstract |
A downhole refractometer apparatus and method include a light source, an optical fiber that receives light emitted from the light source and a fluid cell that receives a downhole fluid. A metalloid interface member is disposed to provide an interface with the downhole fluid in the fluid cell, and a light detecting device detects a light reaction at the metalloid interface member, the downhole fluid property being estimable at least in part based on the light reaction. |
