Oil settles down but off 2-week low; supply concerns in focus

NEW YORK, Oct 28 (Reuters) - Oil prices dipped on Thursday but settled off two-week lows as concerns about U.S. supply growth vied with speculation that Iran's supply could come online following nuclear talks with global powers.

Brent crude settled down 26 cents, or 0.3%, lower at $84.32 a barrel. During the session it hit a two-week low of $82.32 after falling 2.1% on Wednesday.

U.S. West Texas Intermediate (WTI) crude rose 15 cents, or 0.2%, to settle at $82.81. During the session the contract touched a two-week low of $80.58. On Wednesday, the benchmark dropped 2.4% after weekly data showed U.S. crude stockpiles grew more than expected.

On Wednesday, Iran's top nuclear negotiator Ali Bagheri Kani said the country's talks with six world powers to try to revive a 2015 nuclear deal will resume by the end of November.

A deal could pave the way to lifting harsh sanctions imposed by former U.S. President Donald Trump on Iran's oil exports in late 2018.

"The market reacts to these headlines, but may be disappointed by how much oil actually returns," said Phil Flynn, senior analyst at Price Futures Group in Chicago.

U.S. crude stocks rose by 4.3 million barrels last week, the U.S. Energy Department said on Wednesday, more than double the 1.9 million-barrel gain forecast by analysts.

The hefty stockbuild was because of a large jump in net imports of crude oil while refinery processing remained sluggish, Citi Research analysts said in a note.

Yet gasoline stocks fell by 2 million barrels to their lowest in nearly four years, even as U.S. consumers contend with rising pump prices.

At the WTI delivery hub in Cushing, Oklahoma, crude storage was at its lowest levels in three years, with prices for longer-dated futures contracts indicating supplies will remain low for months.

Energy information provider Genscape said that as of Oct. 26, tank levels at Cushing had fallen by 2.772 million in the last week, market participants said.

Outbreaks of coronavirus infections in China and record deaths and the threat of lockdowns in Russia, along with rising cases in western Europe, also weighed on prices.
