SINGAPORE, July 20 (Reuters) – Oil prices were little changed on Thursday as a lower-than-expected drop in U.S. crude inventories and a potentially weaker demand outlook kept investors cautious.

September Brent futures climbed 6 cents, or 0.1%, at $79.52 a barrel by 0645 GMT, while August U.S. West Texas Intermediate (WTI) crude gained 5 cents, or 0.1%, to $75.40 a barrel.

The August WTI contract expires on Thursday. September WTI crude was higher by 6 cents, or 0.1%, to $75.35.

“Following some heavy selling pressure overnight, there is an attempt for oil prices to stabilise this morning,” said Yeap Jun Rong, market strategist at IG.

Prices fell in the previous session as investors took profits after data showed U.S. inventories fell less than analysts expected.

Meanwhile, the U.S. dollar (.DXY) was largely unchanged at 0645 GMT, edging down 0.1%.

The outlook for demand in China, the world’s biggest crude buyer, was also unclear amid its slowing economy.
