Oil prices crept higher on Monday in quiet trade that featured bargain hunting after prices slid to seven-month lows last week, but gains were limited by rising crude supply in the United States and other countries.
Brent crude futures were up 31 cents at $45.85 per barrel by 2:36 p.m. ET (1836 GMT), having hit a trough of $44.35 on June 21, its lowest since November.
U.S. West Texas Intermediate crude futures ended Monday's session 37 cents higher at $43.38 per barrel. They struck $42.05, their lowest level since Aug. 11, also on June 21.
"I think it's mostly bottom fishing at this point," said John Kilduff, partner with energy hedge fund Again Capital in New York, who noted there was some "book squaring" with the end of the quarter approaching.
"After how much we've fallen prices are attractive here as a result, so it's not surprising that we're getting some buying, just on a valuation perspective."
