Oil turned higher on Tuesday, recovering from near six-month lows, as bets for a drop in U.S. crude stockpiles offset worries about a global supply glut and equity market meltdown in China.
U.S. crude reversed earlier losses to settle up 59 cents, or 1.24 percent, at $47.98 a barrel. It rose more than $1 at the session high after touching its lowest since March at $47.68.
Brent was down 20 cents to $53.30 a barrel, after hitting $52.28, the lowest since early February, on earlier concerns about the stock market plunge in China.
The market also saw short-covering after a four-day selloff that wiped between 6 and 7 percent off crude futures, traders said.
Some remained convinced, however, that oil had more to lose, and that a bottom for the market was still far off.
"We're getting a bounce of sorts but I'll be selling into any strength I see," said Tariq Zahir, an oil bear at Tyche Capital Advisors in Laurel Holllow, New York.
The rebound was partly aided by expectations that U.S. crude inventories had fallen last week, after rising to a five-year seasonal average in the prior week, according to government data from last week. That report sparked a selloff in oil.
Stockpiles in the week to July 24 were expected to have fallen 300,000 barrels, a Reuters poll showed on Monday.
The American Petroleum Institute, an industry group, will release its own inventory report at 4:30 p.m. (2030 GMT) on Tuesday before official government data on Wednesday.
U.S. crude futures hit a 2015 high above $62 just three months ago. Technical analysts think the market could lose another $15, falling below the lows of the 2007-2009 financial crisis, due to a combination of poor fundamentals and weak charts.
"Essentially, we see prices staying lower for longer, but that is a function of crude supply response, primarily from the U.S., which remarkably has not shown any signs of slowing at the moment," said Virendra Chauhan, an analyst at consultancy Energy Aspects, in a discussion in the Reuters Global Oil Forum.
Chauhan also said he expected Brent prices to dip below $50, bringing them to January lows.
