Which crude oil has the highest viscosity?
Crude oils – viscosity and °API
Crude Oil | Kin. Viscosity [mm²/s] at Temp. | API Gravity °API |
---|---|---|
Arabian Light | 10.7 at 20 °C | 34.2 |
Bonny Light | 2.90 at 50 °C | 35.4 35.8 |
Boscan | 11233 at 100 °F | 10.1 |
Brent | 2.86 at 50 °C | 37.9 38.2 |
What is the viscosity of crude oil?
(c) The reported values of viscosity for transportation of heavy and extra-heavy crude oils range between 350 cSt at 7 °C and 150 cSt at 50 °C. (d) The most common maximum specification of viscosity for transportation of heavy and extra-heavy crude oils is 250–400 cSt at 37.8 °C.
What is the viscosity of crude oil in Centipoise?

How is crude oil viscosity measured?
To measure absolute viscosity, insert a metal rod into the same two beakers. Use the rod to stir the oil, and then measure the force required to stir each oil at the same rate. The force required to stir the gear oil will be greater than the force required to stir the turbine oil.
Is oil more viscous than water?
More thick a liquid is, more slowly it will flow’. There is no relationship between viscosity and density of a fluid. But oil is more viscous than water and thus when when we put a drop of water and oil on a slant surface, water will move downwards more quickly than the oil drop.
Why is water so viscous?
Besides mercury, water has the highest surface tension for all liquids. Water’s high surface tension is due to the hydrogen bonding in water molecules. Liquids with stronger intermolecular interactions are usually more viscous than liquids with weak intermolecular interactions.
Is honey more viscous than oil?
Liquids that have a HIGH viscosity flow slowly (ie. honey, corn syrup, and molasses). Viscosity can also be thought of as a measure of how “thick” a liquid is. Therefore, we’ve shown that corn syrup and honey have a higher viscosity (or are more viscous) than water and cooking oil.
What is more viscous honey or ketchup?
Very viscous liquids tend to be long chained molecules. For example, honey has a much higher viscosity than water….What is Viscosity.

Honey | 10,000 cps |
Ketchup | 50,000 cps |
Sour Cream | 100,000 cps |
Does pressure affect oil viscosity?
Oil that has a high viscosity is going to be thicker and doesn’t flow as fast as oil with a lower level. This can affect the oil pressure depending on the time of year. It is quite possible that high viscosity will not allow oil pressure to build rapidly.
What are the properties of crude oil?
Although crude oil assays evaluate various chemical properties of the oil, the two most important properties determining a crude’s value are its density (measured as API specific gravity) and its sulphur content (measured per mass). Crude oil is considered ” heavy ” if it has long hydrocarbon chains, or ” light ” if it has short…
How the crude oil is formed?
Crude oil was formed through the conversion of organic substances such as plants and animals (plankton) under the influence of pressure and heat. Crude oil extracted from reservoirs in carrier rock is also known as raw oil. Crude oil extraction is performed onshore (on land) as well as offshore by drilling on the bottom of the ocean.
What is viscous oil?
Viscous Oil is heavy or extra heavy crude oil with high viscosity. Oil Viscosity helps to measure a fluid’s resistance to flow.
