1. A method for producing a virtual assay of an oil sample, wherein the oil sample is characterized by a density, selected from the group consisting of crude oil, bitumen and shale oil, and characterized by naphtha, gas oil, vacuum gas oil and vacuum residue fractions, the method comprising:
entering into a computer Fourier transform infrared (FTIR) spectroscopy data indicative of transmittance over a range of wavenumbers for the oil sample without distillation;
calculating and assigning, as a function of the FTIR spectroscopy data, an analytical value (AV); and
calculating and assigning, as a function of the AV and the density of the oil sample, virtual assay data of the oil sample and the naphtha, gas oil, vacuum gas oil and vacuum residue fractions, said virtual assay data comprising a plurality of assigned data values.
