Oil prices dipped on Monday amid worries about an economic slowdown and the Sino-U.S. trade war, which have led to a cut in the growth outlook for oil demand.
International benchmark Brent crude futures were at $58.35 a barrel by 0249 GMT, down 18 cents, or 0.3%, from their previous settlement.
U.S. West Texas Intermediate (WTI) futures were at $54.29 per barrel, down 21 cents, or 0.4%, from their last close.
Both benchmarks fell last week, with Brent losing more than 5% and WTI falling about 2%.
In a sign of lower production in the United States, the weekly U.S. oil rig count, an early indicator of future output, fell for a sixth week in a row as producers cut spending on new drilling and completions.
