Brent crude futures eased in choppy trading on Friday on improving supply and concerns about tepid demand for oil in Europe and China, while U.S. crude rose on supportive data from the United States.
Slowing economic activity in Europe and Asia has dampened demand for oil, while supply is on the rise. Libya's output has reached 925,000 barrels per day (bpd), the highest since militias turned on each other after the overthrow of Muammar Gaddafi.
The U.S. economy grew at its fastest pace in 2-1/2 years in the second quarter with all sectors contributing to the jump in output, the Commerce Department said. The report raised the estimate of gross domestic product (GDP) to show the economy expanded at a 4.6 percent annual rate, in line with Wall Street's expectations.
