ABSTRACT:
The invention is a method of evaluating a sample of an underground formation such as drill cuttings to determine the producibility of any hydrocarbons present in the formation by solvating a sample in a polar solvent which will solvate asphaltenes, solvating the sample in an aliphatic solvent which will solvate most crude fractions without solvating asphaltenes, quantitatively measuring the emission fluorescence at a wavelength below 400 nm of both solvated samples at an excitation wavelength at which most petroleum compounds fluoresce, and determining the producibility of any hydrocarbon present in the sample by comparing the emission fluorescence of the two samples to previous correlations made between fluorescence and known producibility.
