* US Feb non-farm payrolls rise by 175,000, beat forecast
* Putin rebuffs Obama as Ukraine crisis escalates
* U.S. crude heads for first weekly drop in 8 weeks
LONDON, March 7 (Reuters) - Oil edged above $108 a barrel on Friday as supply concerns arising from the Ukraine crisis and a better-than-expected U.S. jobs report offset a seasonal slowdown in demand for crude.
Data showed U.S. non-farm payrolls rose by 175,000 in February, more than forecast. The Ukraine crisis escalated as President Vladimir Putin rebuffed a warning from U.S. President Barack Obama over Moscow's military intervention in Crimea.
Global benchmark Brent was up 19 cents at $108.29 a barrel at 1440 GMT. It settled up 34 cents on Thursday. U.S. crude, also known as WTI, was up 62 cents at $102.18, after closing 11 cents higher.
"The oil market is reacting relatively calmly to the tensions that are once again escalating in the Crimean crisis," said Barbara Lambrecht, an analyst at Commerzbank in Frankfurt. "Evidently the market is comfortably balanced at present."
Both benchmarks were on track to end the week lower. Brent was heading for a second straight weekly decline, despite supply disruptions in Libya, and the U.S. contract for its first drop in eight weeks.
Political tensions aside, analysts see the onset of spring in the northern hemisphere, bringing warmer weather and refinery maintenance, as likely to curb demand and limit price gains.
"We remain sceptical over any WTI or Brent upside in the near future amid the seasonal refinery turnaround season," said Andrey Kryuchenkov, an analyst at VTB Capital in London.
Oil jumped on Monday after military intervention by Russia, one of the world's top oil exporters, on the Crimean peninsula. Brent has fallen from Monday's high above $112 as the risk of war faded.
Concerns over Ukraine increased again after Crimea's Moscow-backed parliament voted to join Russia on Thursday and scheduled a referendum on the split for March 16.
Before Putin and Obama spoke on Thursday, the U.S. president announced the first sanctions against Russia since the start of the crisis.
