The petroleum barrel developed from nineteenth-century oil production and transport in the United States, when wooden barrels were a practical container for shipping crude. Although barrel sizes varied, the petroleum industry eventually standardized the US oil barrel at 42 US gallons, a convention recognized in the early twentieth century. Reporting production as barrels per day became common as oil fields, refineries, and markets expanded. Today, bbl/d is a customary industry measure rather than a direct statement that liquids are physically stored in individual barrels.
