Abstract
The invention comprises an apparatus and method for simple fluorescence spectrometry in a downhole environment using a UV light source and UV fluorescence to determine a parameter of interest for a sample downhole. The UV light source illuminates the fluid, which in turn fluoresces light. The fluoresced light is transmitted back towards the UV light source and through the pathway towards an optical spectrum analyzer. API gravity is determined by correlation the wavelength of peak fluorescence and brightness of fluorescent emission of the sample. Asphaltene precipitation pressure is determined by monitoring the blue green content ratio for a sample under going depressurization.
