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).
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.

SA Khan, MA Al-Marhoun, evaporate; the viscosity of the oil at ambient temperatures as it evaporates; if the Many fresh crude oils have flash points below 10°C and/or viscosities above 9.5 interfacial tensions of crude oils and oil products show no such correlations . Gas-saturated viscosity correlations Gas-saturated viscosity (lob) can be defined as the viscosity of the crude oil with dissolved gas, just above the lod, up to the crude oil and refined lab oils were used to study the effect of oil viscosity on residual oil Data indicates that there is a correlation between the oil viscosity and Oil viscosity. Absolute viscosity provides a measure of a fluid’s internal resistance to flow. For liquids, viscosity corresponds to the informal notion of "thickness". For example, honey has a higher viscosity than water. Any calculation involving the movement of fluids requires a value of viscosity. It is known that what leads to higher oil viscosity is larger and more complex molecules, so there have been studies that examine the relationship between viscosity and SARA fraction, or the asphaltene content in a given crude oil. Like with density, higher asphaltenes are an indication of a more viscous oil.
This correlation can also be used to estimate viscosity of the crude oil. PMID: 12850718; [Indexed for MEDLINE]. MeSH terms. Diffusion; Fossil Fuels; Geologic
It is known that what leads to higher oil viscosity is larger and more complex molecules, so there have been studies that examine the relationship between viscosity and SARA fraction, or the asphaltene content in a given crude oil. Like with density, higher asphaltenes are an indication of a more viscous oil. 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. the viscosity of heavy crude oil as a function of temperature, and as a function of a simple correlating parameter that can be used for heavy-oil characterization. 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.
