TOKYO/LONDON- Oil prices were steady on Thursday as producers including Saudi Arabia and Russia locked horns over the need to extend record production cuts set in place during the first wave of the COVID-19 pandemic.

Brent crude was up 4 cents, or less than 1%, at $48.29 a barrel by 1337 GMT, and U.S. oil was down 1 cent, or less than 0.1%, at $45.27 a barrel.

"The market is cautious. Oil prices lost some gains this week as negotiations within the OPEC+ group did not prove to be as smooth as expected," said Rystad Energy’s head of oil markets Bjornar Tonhaugen.

The Organization of the Petroleum Exporting Countries (OPEC) and its allies including Russia, known as OPEC+, are resuming discussions on Thursday to agree on policies for 2021 after earlier talks had no conclusion on how to tackle weak oil demand amid a new coronavirus wave.

OPEC and Russia have moved closer to a compromise, OPEC+ sources told Reuters. 

OPEC+ had been widely expected to roll over oil cuts of 7.7 million barrels per day, or 8% of global supplies, at least until March 2021.

But after hopes for a speedy approval of COVID-19 vaccines spurred a rally in oil prices at the end of November, some producers questioned the need to tighten oil policy, which is supported by OPEC leader Saudi Arabia.

"It is still expected that the group will come to a deal," ING Economics said in a note.

Britain approved Pfizer Inc's COVID-19 vaccine on Wednesday, jumping ahead in a global race to start the most crucial mass inoculation programme in history.

In the United States, crude stockpiles fell last week, while gasoline and distillate inventories rose sharply as refiners slowed production amid weakening demand, the Energy Information Administration said on Wednesday. 

Oil stocks fell by 679,000 barrels in the week to Nov. 27, less than the 2.4 million-barrel decline forecast in a Reuters poll of analysts.

Gasoline stocks increased by 3.5 million barrels, while distillate inventories were up by 3.2 million barrels.
