New York - Persistent worries about a global oversupply of crude oil weighed on the oil market Thursday after US inventories leapt to another record high this week.
US benchmark West Texas Intermediate for delivery in April fell 77 cents to $50.76 a barrel on the New York Mercantile Exchange at the end of a volatile session in which WTI spent some time in positive territory.
In London, Brent North Sea crude for April, the international benchmark, dipped 7c to $60.48 a barrel.
