Measurement of Viscosity of Hydrocarbon Liquids Using a Microviscometer

Research output: Contribution to journalJournal articleResearchpeer-review


The viscosity of normal alkanes, their mixtures, and true boiling point (TBP) fractions (C (sub 6) -C (sub 19)) of four North Sea petroleum reservoir fluids have been measured by use of an automatic rolling ball mixroviscometer at 20°C. The equipment is specially suited for samples of limited amount as only 120 to 2500 micro l. is required depending on the viscosity range. The densities of the fluids were also determined. The accuracy of these measurements is ascertained and compared with literature data on n-alkane mixtures. The data reported for reservoir fluids includes molecular weights as well as density. Finally, generalized viscosity correlations for the C (sub 6) to C (sub 19) fractions are discussed.
