METHODS AND SYSTEMS FOR QUANTIFYING THE GRADE OF PETROLEUM OIL BASED ON FLUORESCENCE

摘要

Systems and methods evaluate the grade or API gravity of petroleum. The methods and systems disclosed herein overcome many of the difficulties commonly associated with petroleum exploration. The methods and systems include collecting fluorescence emission spectra of soil samples and inputting these into an artificial neural network, which is able to rapidly and accurately assess and classify data from multiple soil samples. Additionally, the methods and systems can be useful in identifying other compounds related to or commonly found together with petroleum, including hydrocarbons and aromatic compounds.

1. A method for determining the grade of petroleum in a sample, the method comprising:
a. obtaining a sample comprising petroleum; b. contacting the sample with a digestion composition; c. filtering the sample in order to isolate a filtrate; d. quantifying the amount of fluorescence produced by the filtrate; e. comparing the amount of fluorescence in the filtrate to a standard curve, where the curve correlates the amount of fluorescence to the grade of petroleum; and f. identifying the grade of petroleum in the sample.
