Which crude-oil field gave its name to the Brent benchmark?

The Brent field gave its name to the Brent crude-oil benchmark.

The field lies in the North Sea, east of the Shetland Islands, in the United Kingdom’s sector. It was discovered in 1971, and production began in 1976. The name Brent came from Shell’s practice of naming North Sea fields after birds; Brent refers to the brent goose.

The Brent benchmark originally referred to crude produced from the field. Over time, the physical reference stream evolved as production from the original field declined. Modern Brent pricing uses a broader basket of North Sea crude grades, including several streams associated with the wider Brent complex.

Brent is one of the world’s most important oil-price references and is commonly contrasted with West Texas Intermediate, which is associated with the United States. The field name therefore became globally influential even though the original field is no longer the sole source of the benchmark.
