Broken pipeline cuts British supply during peak energy demand

LONDON (Reuters) - Britain's biggest pipeline from its North Sea oil and gas fields is likely to be shut for several weeks for repairs, its operator said on Tuesday, disrupting gas flows and sending international crude prices to their highest since mid-2015.

The closure has struck during a winter freeze in Britain, where snow and ice have driven up demand for heating fuel just as gas flows through the network, which carries a third of Britain's gas produced offshore, were disrupted.

"We're hearing it will be likely down for two weeks," an industry source familiar with the operations said.

The pipeline, which carries about 450,000 barrels per day (bpd) of Forties crude, was shut after cracks were found.

It has particular significance to global markets because Forties is the largest out of the five crude oil streams that underpin the dated Brent benchmark, against which other crude prices are broadly based. Benchmark Brent crude prices rose above $65 per barrel for the first time since the middle of 2015 following the closure on Monday.

INEOS, which only completed the purchase of the Forties pipeline system from oil major BP in October, said it was too soon to say how long repairs would last, but that it would be "weeks rather than days."

A minor leak had caused a partial shutdown on Dec. 7.

Paul Wheelhouse, the Scottish Energy Minister, said there were no plans to shut the 200,000 bpd Grangemouth refinery, which uses Forties crude.

"A technical assessment is under way to inform the repairs required and the likely duration of the shutdown. There are no plans to shut down Grangemouth refinery and no impacts are anticipated for fuel and gas supplies," he told the devolved Scottish parliament.

"If it's a lengthy outage, then a recovery period for the fields will be long as well," the trading source said.

FIELDS CLOSING

A number of producers including BP, Shell and Chrysaor, said they had closed down oil fields in response.

The largest contributor to the Forties stream, the 180,000-bpd Buzzard oil field run by Nexen Petroleum UK Ltd, a subsidiary of China's CNOOC, had also closed, two trading sources said.

Monthly loading programmes show the supply of Forties is expected to reach 21 cargoes of 600,000 barrels each this month, equal to a daily supply rate of 406,000 bpd.

The closure has created havoc with loading schedules in the North Sea, with one trading source saying cargo owners had been offered options to drop cargoes from the loading programme.

"At this point we would expect a large deferral list for the Forties loading programme to spill over into January," analysts from JBC Energy said in a note.

INEOS was due to meet with producers including oil majors on Tuesday to discuss the situation, trading sources said.

"The timing of the outage could not be much worse as winter weather is just materialising," Jefferies bank analysts wrote.

Jefferies estimated the closure resulted in production loss for BP of 105,000 bpd, for Total of 55,000 bpd, for Chevron of 45,000 bpd, for Exxon Mobil of 40,000, for Eni of 25,000 bpd, for Shell of 25,000 bpd, for ConocoPhillips of 15,000 bpd.

The Paris-based International Energy Agency, which advises Western governments and coordinates the release of oil from strategic stocks in the case of supply disruptions, said it stood ready to take action but it did not believe this was necessary for the time being.

"We are monitoring the situation closely, and stand ready to act, but at the moment we see no need as the market is amply supplied from other sources and stocks are well above the five-year average," the IEA said.
