LONDON (Reuters) -Oil was broadly stable on Wednesday as concerns about escalating hostilities in the Ukraine war potentially disrupting oil supply from Russia offset data showing rising stocks.

futures for January were up 22 cents, or 0.3%, to $73.53 a barrel at 1026 GMT. U.S. West Texas Intermediate crude futures for December, due to expire on Wednesday, were up 31 cents, or 0.5%, to $69.70, while the more active WTI contract for January was up 24 cents at $69.48.

The escalating war between major oil producer Russia and Ukraine has kept a floor under the market this week.

“We may expect (Brent) oil prices to stay supported above the $70 level for now, as market participants continue to monitor the geopolitical developments,” said Yeap Jun Rong, market strategist at IG.

On Tuesday, Ukraine used U.S. ATACMS missiles to strike Russian territory for the first time, Moscow said, while Russian President Vladimir Putin lowered the bar for a possible nuclear attack.

“The price action in the oil market has been relatively uneventful post-U.S. election, with some pick-up in the past couple of days due to a temporary production outage in the North Sea and a further escalation in the nature of the confrontation in Ukraine,” said Harry Tchilinguirian, head of research at Onyx Capital Group.

Norway’s Equinor on Wednesday said it restored full output capacity at the Johan Sverdrup oilfield in the North Sea following a power outage. Equinor last month said the field was producing at peak capacity of around 755,000 barrels of oil equivalent per day (boed).

On the demand side, U.S. crude oil stocks rose by 4.75 million barrels in the week ended Nov. 15, market sources said on Tuesday, citing American Petroleum Institute figures.

That was a bigger build than the 100,000-barrel increase analysts polled by Reuters were expecting.

Gasoline inventories, however, fell by 2.48 million barrels, compared with analysts’ expectations for a 900,000-barrel increase.

Distillate stocks also fell, shedding 688,000 barrels last week, the sources said.

Official government data is due later on Wednesday.

“If we get a confirmation of the API’s preliminary crude stock build figure, the market is likely to retrace lower to the levels seen at the start of the week,” Onyx Capital’s Tchilinguirian said.
