Investing.com - Oil prices edged lower Thursday, snapping three days of gains, as mounting U.S. inventories weighed. While U.S. crude inventories rose to a new record last week, output fell for a sixth straight week the EIA said. U.S. production cuts are helping support prices, but investors are also looking to U.S. jobs data later Friday to give further direction. Positive U.S. jobs data could maintain the momentum of higher oil prices. Oil prices have recovered more than 30% from February’s lows, but remain down nearly 70% from their June 2014 peak on oversupply concerns
