As previously mentioned, the brent blend is a mix of crude oil from several facilities in the Ninian and Brent fields on the North Sea. Much like the other internationally recognized benchmark for crude oil, West Texas Intermediate, the Brent blend is a light and sweet crude oil, though not as light or sweet as WTI. Brent futures are traded on both the ICE and NYMEX exchanges, with delivery dates for all 12 months of the year.
