Crude oil prices rose more than $1 a barrel on Friday, continuing a rebound from near-six-year lows plumbed last week, although no rapid recovery is expected amid rising global inventories and steady OPEC supply.
Prices closed more than 4 percent higher on Thursday, pushed up by conflict in producer Libya and expectations of a boost to oil demand after China's central bank easing.
Benchmark Brent crude futures were $1 higher at $57.57 a barrel at 0741 GMT (2.41 a.m. EST), after closing up $2.41 on Thursday.
U.S. crude for March delivery was also up $1 at $51.47 a barrel. The contract had finished up $2.03 the previous day.
