Title: METHOD AND SYSTEM FOR STABILITY DETERMINATION OF ASPHALTENES UTILIZING DIELECTRIC CONSTANT MEASUREMENTS
Abstract:
A method of determining asphaltene stability within a crude oil sample that includes obtaining a crude oil sample and performing a fractional analysis of the crude oil sample. The method further includes measuring, via a cylindrical capacitor, a dielectric constant of the crude oil sample and its fractions. Responsive to the measured dielectric constant, the stability of the asphaltenes within crude oil sample is determined.
