  1. What is an oil benchmark?

    Choices: A reference price for a defined crude market · Every oil trade in the world · A tax on petrol

    Show the answer

    A reference price for a defined crude market. A benchmark is a reference tied to a particular crude stream, location and market—not one universal oil price.

  2. How many US gallons are in a standard oil barrel?

    Choices: 42 · 50 · 100

    Show the answer

    42. A standard oil barrel contains 42 US gallons, or roughly 159 litres.

  3. If Brent is $4 above WTI, what does the $4 describe?

    Choices: The benchmark spread · The refinery yield · The exchange rate

    Show the answer

    The benchmark spread. The spread is the price difference between the two benchmarks on comparable dates and in comparable units.

  4. Does a higher API gravity usually mean a lighter crude oil?

    Choices: Yes · No

    Show the answer

    Yes. Yes. Higher API gravity generally describes a crude with lower density relative to water.

  5. Why should you check both dates before comparing two oil prices?

    Choices: They may describe different market days · Oil has no units · Dates change barrel size

    Show the answer

    They may describe different market days. Prices from different days experienced different market conditions. A fair comparison aligns observation dates.
