Oman crude gained $1.85 per barrel in trading on the Dubai Mercantile Exchange (DME) on Friday to settle at $80.71 per barrel, which like other international benchmarks was boosted by concerns over unrest in Kazakhstan and outages in Libya.

According to Reuters, international oil prices rose and were heading for their biggest weekly gains since mid-December on Friday as problems in Kazakhstan and Libya spurred concerns over supply.

Brent crude climbed 70 cents, or 0.9 per cent, to $82.69 a barrel at 1229 GMT. US West Texas Intermediate (WTI) crude rose 59 cents, or 0.7 per cent, to $80.05 a barrel.

Brent and WTI were on track for gains of almost 6.5 per cent in the first week of the year, with prices at their highest since late November, as supply concerns overtook worries that the rapid spread of the Omicron coronavirus variant might hurt demand.

“The upward jump in oil prices mostly reflects the market jitters as unrest escalates in Kazakhstan and the political situation in Libya continues to deteriorate and sideline oil output,” Rystad Energy analyst Louise Dickson said.

Oil production at Kazakhstan’s top field Tengiz was reduced on Thursday, its operator Chevron said, as some contractors disrupted train lines in support of protests taking place across the central Asian country.

Meanwhile, supply additions from the Organisation of the Petroleum Exporting Countries, Russia and allies, together called OPEC+, are not keeping up with demand growth.

OPEC’s output in December rose by 70,000 barrels per day from the previous month, versus the 253,000 bpd increase allowed under the OPEC+ supply deal, which restored output that was slashed in 2020 when demand collapsed under COVID-19 lockdowns.

Production in Libya has dropped to 729,000 barrels per day, down from a high of 1.3 million bpd last year, partly due to pipeline maintenance work.

While the Omicron coronavirus variant is rapidly taking hold, demand-side concerns are easing amid rising evidence that it is less severe than previous variants.

“The concerns about a massive slump in oil demand have faded now that it has become clear that Omicron leads to milder forms of the disease than previous variants of the virus, meaning that massive mobility restrictions are not likely,” said Commerzbank analyst Carsten Fritsch.
