Traders said growth in U.S. output was counteracting efforts by the Organization of the Petroleum Exporting Countries (OPEC) and other producers including Russia to reduce a global fuel overhang, resulting in range-bound prices.

"U.S. producer hedging via futures and increasing shale production offset the progress OPEC has made with its production cut implementation," said Jeffrey Halley, senior market analyst at futures brokerage OANDA in Singapore.

"Market participants are hyper-focused on two issues: shale's response to higher prices and OPEC compliance," Barclays bank said.

U.S. oil production, however, has risen by around half a million barrels per day since mid-2016 to 8.96 million bpd.
