what is the origin of the name brent crude oil
Brent Crude Originally Brent Crude was produced from the Brent oilfield. The name "Brent" comes from the naming policy of Shell UK Exploration and Production, operating on behalf of ExxonMobil and Royal Dutch Shell, which originally named all of its fields after birds (in this case the brent goose).[1][2][3][4] But it is also a backronym or mnemonic for the formation layers of the oil field: Broom, Rannoch, Etive, Ness and Tarbert.[5]
Petroleum Petroleum (from Ancient Greek: petra: "rock" + oleum: "oil"[1][2][3][4][5][6]) is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels. Components of petroleum are separated using a technique called fractional distillation i.e. separation of a liquid mixture into fractions differing in boiling point by means of distillation, typically using a fractionating column.
