Brent Crude may refer to any or all of the components of the Brent Complex, a physically and financially traded oil market based around the North Sea of Northwest Europe; colloquially, Brent Crude usually refers to the price of the ICE Brent Crude Oil futures contract or the contract itself. The original Brent Crude referred to a trading classification of sweet light crude oil first extracted from the Brent oilfield in the North Sea in 1976. As production from the Brent oilfield declined to zero in 2021, crude oil blends from other oil fields have been added to the trade classification. The current Brent blend consists of crude oil produced from the Forties, Oseberg, Ekofisk, Troll oil fields and oil drilled from Midland, Texas in the Permian Basin.
