Heavy oil density and viscosity
In this study, crude oils from Malaysian oil fields are studied to determine their wax formation tendency for flow assurance purposes. For this study, density, 10 May 2012 Physically heavy crude oil have higher viscosity and density or specific gravity with an heavier molecular composition. Heavy crude oil has Kinematic viscosity can also be calculated from dynamic viscosity and density data determined at the same temperature. rate shear stress shear. Viscosity. and the fluids typically have a viscosity in the range of 0.5 to 4 cP (mPa.s) but may be as high as 40 cP in heavy oils. Fluid density can range from 0.2 up to 1.5 g/cc.
For example, the viscosity of Venezuela's Orinoco extra-heavy crude oil lies in the range 1000–5000 cP (1–5 Pa·s), while Canadian extra-heavy crude has a viscosity in the range 5000–10,000 cP (5–10 Pa·s), about the same as molasses, and higher (up to 100,000 cP or 100 Pa·s for the most viscous commercially exploitable deposits).
Heavy Fuel Oil HFO, also known as “residual fuel oil”, is based on the high viscosity, tar-like mass, which remains after the distillation and subsequent cracking of crude oil in order to produce lighter hydrocarbon products, such as petrol, distillate diesel fuels and heating oil or feedstocks for lubricants. The generic term heavy fuel oil (HFO) describes fuels used to generate motion and/or fuels to generate heat that have a particularly high viscosity and density. In the MARPOL Marine Convention of 1973, heavy fuel oil is defined either by a density of greater than 900 kg/m³ at 15°C or a kinematic viscosity of more than 180 mm²/s at 50°C. erally related to crude oil properties, such as density and viscosity. The most widely used definition for heavy oils is based on the API gravity1 proposed by the American Petroleum Institute, which uses the oAPI scale (index that is based on the oil relative density) as the criterion for oil classification. The API degree The viscosity of the gas saturated oil is found as a function of dead oil viscosity and solution gas-oil ratio (GOR). Undersaturated oil viscosity is determined as a function of gas saturated oil viscosity and pressure above saturation pressure. Figs. 3 and 4 summarize all of the dead oil viscosity correlations described in Tables 2 and 3.
viscosities adjusted accordingly. For each dead oil viscosity measurement, it is important to know the fluid density as well as the analysis temperature. When the
A total of 30 heavy oil samples of different API gravities ranging from 11.7 to 18.8 were tested. Viscosity and density were measured in the temperature range from 20 to 160 °C. The accuracy of the experimental density data was determined using Standing and Katz method. For example, the viscosity of Venezuela's Orinoco extra-heavy crude oil lies in the range 1000–5000 cP (1–5 Pa·s), while Canadian extra-heavy crude has a viscosity in the range 5000–10,000 cP (5–10 Pa·s), about the same as molasses, and higher (up to 100,000 cP or 100 Pa·s for the most viscous commercially exploitable deposits). The density of the heavy oil in the Shanjiasi field is up to 0.9719 g/cm 3, and the dynamic viscosity of this heavy oil reaches hundreds to thousands of mPa·s at 50 °C. Even as the temperature has been increased to 80 °C or 100 °C, their dynamic viscosity is still as high as dozens of mPa·s. increased the demand for heavy oil in the international market. Crude oil is classified as light or heavy oil based on different physical properties, such as molecular weight, viscosity, density, and API gravity. The most common definition of heavy crude oil is crude oil with API gravity less than 20, according to the International Energy Agency

The term “Heavy Oil” is a reference to the high density. (API Gravity) of those oils. The measurement that we care most about today is viscosity since that is the erally related to crude oil properties, such as density and viscosity. The most widely used definition for heavy oils is based on the API gravity1 proposed by the 4 Jun 2015 Viscosity increases with decreases in crude oil API gravity (assuming a constant Watson characterization factor) and decreases in temperature. The density of the heavy oil in the Shanjiasi field is up to 0.9719 g/cm3. The dynamic viscosity of this heavy oil reaches hundreds of thousands of millipascal- 19 Jul 2013 The demand for transport, together with the increasing scarcity of world fuel resources, has been responsible for many of the advances in crude
