Abstract
Impedance is used to determine the performance of paraffin inhibitors in oil containing paraffin. The method and system can use a specially designed impedance cell having a cell constant of less than 1 cm. Further, the method can include obtaining at least impedance measurements above the wax appearance temperature (WAT) for an oil sample treated with a paraffin inhibitor and an oil sample not treated, and impedance measurements below the WAT for the treated oil sample and the untreated oil sample. Thereafter, the impedance measurements are correlated to determine paraffin inhibitor performance.
