Abstract
Methods including: measuring a mid and/or near Fourier-transform infrared (FTIR) and/or Raman spectrum of a hydrocarbon fluid; determining an estimated cold filter plugging point (CFPP) for the hydrocarbon fluid using a vibrational spectroscopy-CFPP correlation model; and treating the hydrocarbon fluid to cause a change in the estimated CFPP. In some cases, the treating of the hydrocarbon fluid comprises: adding a flow improver to the hydrocarbon fluid.
