摘要： A method of analyzing a fluid includes acquiring a sample of the fluid extracted from a subterranean region proximate to a borehole, the borehole including an injected fluid, applying light having a first excitation wavelength to the fluid sample, and measuring a first fluorescence spectrum. The method also includes comparing the first fluorescence spectrum to a reference fluorescence spectrum corresponding to a fluid having injected fluid contamination and/or to a second fluorescence spectrum based on applying light having a second excitation wavelength to the fluid sample. The method further includes estimating a level of contamination of the fluid sample with the injected fluid based on the comparing.
