Method and system for stability determination of asphaltenes utilizing dielectric constant measurements
MetadataShow full item record
A method of determining if unstable asphaltenes are present in a crude oil sample includes obtaining a crude oil sample and performing a fractional analysis of the crude oil sample. In one embodiment, the method further includes measuring, via a cylindrical capacitor, a dielectric constant of the crude oil sample. Responsive to the measured dielectric constant, presence of unstable asphaltenes within the crude oil sample is determined. Responsive to the determined presence of unstable asphaltenes in an amount above a predetermined value, asphaltene precipitation is mitigated by addition of a chemical additive to the well.
