ABSTRACT:
A method and apparatus is described for determining a parameter of interest of a formation fluid. The method comprises moving a tool attached to a tubular member along a borehole in a subterranean formation. The tool is used to determine the refractive index, pressure and temperature of a formation fluid sample, in situ, at a predetermined location along the borehole. A refractive index of a reference fluid is calculated at the sample conditions. The parameter of interest of the formation fluid is determined at the predetermined location from a comparison of the corresponding formation fluid refractive index and the reference fluid refractive index at the predetermined location. In another embodiment, the refractive index of a natural gas sample is determined and compared to the refractive index of pure methane, at downhole conditions, to indicate the dryness of the natural gas.
