Summary:Methods and related systems are described for real-time wellsite production allocation analysis. Spectroscopic in-situ measurements are made in the vicinity of a wellsite of a produced fluid from one or more boreholes. The produced fluid includes in a co-mingled state, at least a first fluid component from a first production zone and a second fluid component from a second production zone. An allocation is estimated in real-time for at least the first fluid component in the produced fluid based at least in part on the spectroscopic in-situ measurements. The in-situ measurements can be several types, for example: (1) absorption of electromagnetic radiation having wavelengths in the range of ultraviolet, visible and/or infrared light, (2) X-ray fluorescence spectroscopy measurements, (3) electromagnetic scattering spectroscopic measurements such as Raman spectroscopy measurements, (4) NMR spectroscopy measurements, and (5) terahertz time-domain spectroscopy measurements.
