Crude Oil Properties and Classifications

The video tutorial 'Oil 101' introduces crude oil, explaining its properties, composition, and classification. It covers the significance of API gravity in measuring oil density and the impact of sulfur content on oil quality. The historical context of oil measurement and the economic value of different crude types are also discussed, highlighting the importance of light and sweet crudes.

What are the two main classifications of crude oil based on its properties?

• Dense and sparse

• Hot and cold

• Solid and liquid

• Light and heavy

What is the primary component of crude oil?

• Water

• Hydrocarbons

• Sulfur

• Oxygen

How does the number of carbon atoms in a hydrocarbon molecule affect its boiling point?

• It decreases the boiling point

• It makes it evaporate faster

• It has no effect

• It increases the boiling point

What is the method used by the oil industry to measure the density of crude oil?

• API gravity

• Volume measurement

• Weight comparison

• Specific gravity

What does a higher API gravity indicate about a crude oil compound?

• It is more viscous

• It has more sulfur

• It is lighter

• It is heavier

What sulfur content percentage classifies crude oil as sweet?

• Exactly 1%

• More than 2%

• Less than 0.5%

• Between 1% and 2%

Why was the term 'sweet' used to describe certain crude oils historically?

• Because they were less dense

• Because of their color

• Due to their low sulfur content

• Due to their pleasant taste

What is the relationship between API gravity and the economic value of crude oil?

• Higher API gravity decreases value

• Higher API gravity increases value

• API gravity has no effect on value

• API gravity only affects color

Which type of crude oil commands a higher price?

• Sour heavy crude

• Sweet heavy crude

• Sweet light crude

• Sour light crude

Why is it costly to process sour crude oils?

• Due to their low boiling point

• Because they are rare

• Because of their high sulfur content

• Due to their high density
