Supply of the five North Sea crude oil grades underpinning the dated Brent benchmark will average about 565,000 barrels per day (bpd) in March, up from 550,000 bpd in February, loading programmes showed.

Brent, Forties, Oseberg, Ekofisk and Troll are the five North Sea grades underpinning the dated Brent benchmark. U.S. WTI Midland crude, which is also part of the benchmark, does not have a loading programme.
