27 Jan 2018 correlations for estimating viscosity of live crude oils by comparing with our experimental data of undersaturated oil viscosity. In this work
The live oil viscosity is often estimated from correlations which account for the effect of dissolved gas and pressure on the viscosity of dead (stabilised) oil. The viscosity of gas-free crude oil can be estimated from correlations of Beal [57], Beggs-Robinson [58], Egbogah-Ng [59], or Labedi [60], to name a few. While Beal correlated dead oil viscosity as a function of API gravity and temperature, Chen and Connally presented a correlation for the effect of dissolved gas on oil viscosity. More recently, Beggs and Robinson, (3) presented an empirical viscosity correlation equation for dead or gas-free crude oil as a function of API gravity and temperature.

Crude oil viscosity is an important physical property that controls and influences the flow of oil through porous media and pipes. It is defined as the internal resistance of the fluid to flow. New viscosity correlations for dead crude oils. Based on a non-linear regression method, using relatively a large set of experimental data, new comprehensive correlations for prediction of viscosity of the Iranian heavy and light dead crude oils have been developed. The correlation originated from analyzing 460 dead oil viscosity measurements. The data set from which the results were obtained ranged from 16°API to 58°API and 70°F to 295°F. The correlation tends to overstate the viscosity of the crude oil when dealing in temperature ranges below 100°F to 150°F.
Crude oil is a complex mixture of various components. Depending on its geographic origin, its chemical composition and consistency vary. The different types of crude oil need to be classified for further treatment. Both a crude oil's viscosity and its API (American Petroleum Institute) degree are important parameters for classification.
An Improved Correlation Approach to Predict Viscosity of Crude Oil Systems on the NCS. Møller, Jørgen Bergsagel. Master thesis. Thumbnail. View Physical properties that differ between heavy crude oils and lighter grades include higher viscosity and specific gravity, as well as heavier molecular composition For this study, density, viscosity and pour point of all crude oils is measured at different temperaturesis calculated by using correlation equation (Brown, 1996). The Puttangunta et al model for the viscosity's of conventional light crude oil is a one parameter viscosity in which temperature correlation was developed from
Yield structure of crude oils with increasing density of crude - Yields of different crude oil distillation cuts are plotted as function of whole crude specific gravity. Fractions based on European and North American markeds, and the typical differences in crude oil fractionation in the two markeds are also shown.

Oil Viscosity Below the Bubble Point It is the viscosity of crude oil below the bubble point pressure and a given temperature. With the point pressure and a given temperature. With the lowering of pressure below the bubble point pressure, gas is released leaving behind a saturated oil at the new pressure.
