Oil prices on Wednesday continued growth that began in the previous session, reacting to supply disruptions in Libya and expectation that OPEC cuts will be extended in the second half of 2017.
Brent crude futures rose 29 cents, or 0.6%, to $51.62 a barrel.
In the U.S., WTI crude futures rose 34 cents, or 0.7 percent, to $48.71 a barrel.
The increase added to a growth of more than 1% for both crude brands.
Oil production in the U.S. rose sharply again this year and the increase in stocks of raw materials allows traders to expect further growth of black gold export in 2017.
