In the context of global oil prices, “Brent crude oil” is frequently referred to in the news. What does this term imply?

  1. 1.It is a major classification of crude oil.
  2. 2.It is sourced from the North Sea.
  3. 3.It does not contain sulphur.

Which of the statements given above is/are correct?

Answer & explanation

Answer: (b) 1 and 2 only

Brent is a benchmark (marker) crude used to price many other crudes, and it is produced in the North Sea, so statements 1 and 2 are correct. It is a light, sweet crude. Sweet means low in sulphur, not free of sulphur, so statement 3 is wrong.

  • ✓ 1. Brent is one of the world's major crude benchmarks, alongside WTI and Dubai/Oman. It serves as a reference or 'marker' for pricing many other crude streams.
  • ✓ 2. Brent comes from the North Sea. It is a blend of streams such as Brent and Forties (produced offshore the UK) and Ekofisk and Oseberg (produced offshore Norway).
  • ✗ 3. Brent is 'sweet', which means low sulphur content. Sweet crude still contains some sulphur, so 'does not contain sulphur' is wrong.
  • ✗ (d) Option (d) fails because it includes statement 3. Option (c) fails because it includes statement 3 and leaves out statement 2.

Remember · Brent = North Sea light sweet crude and a global price benchmark. 'Sweet' means low sulphur, not zero sulphur. WTI is the US benchmark; Dubai/Oman is the Gulf benchmark.
