The world’s biggest oil and gas producers, already cutting hundreds of jobs a week from the U.K.’s North Sea, are just warming up, Bloomberg reported Feb. 25.

About 1,500 jobs have been lost in offshore oil and gas this year, according to Unite, Britain’s largest labor union. Ian Wood, author of a state-ordered report into the needs of the business, warned in an interview on Feb. 24 that about 15,000 positions relying on the industry could vanish in a few months.

BP Plc (NYSE: BP), Royal Dutch Shell Plc (NYSE: RDS-A, RDS-B) and Total SA (NYSE: TOT) are among those reducing staff, curbing investment or closing operations as oil prices that have fallen by half since June add to troubles from rising costs and aging resources.

“The 1,500 redundancies; that’s just the start,” John Taylor, Unite’s regional organizer, said by phone from Aberdeen, the Scottish city at the heart of the U.K. industry. “Half of that is drilling. There’ll be more construction workers later as projects come to an end in the next two months.”

The early layoffs portend hard times for a whole ecosystem of explorers, drillers, producers and service companies, along with businesses that rely on the local demand they create. About a quarter or a third of U.K. fields are uneconomic at current oil prices, BP CEO Bob Dudley said this month. His company announced 300 job cuts already this year.

Investment Drop

“The main challenge for the North Sea is that fields that could produce for 10 to 15 more years will be shut down earlier if the prices we are currently seeing persist,” Philipp Chladek, an analyst at Bloomberg Intelligence, said by phone.

Petrofac Ltd., a U.K. oil-services provider, cut contract rates by 20% and froze pay to stay competitive, CEO Ayman Asfari, said Feb. 25 in a Bloomberg TV interview. “The cost structure in the North Sea isn’t sustainable,” he said, calling on the government to introduce tax relief on new investments.

Investment will drop by more than half this year and 70% by 2018 on weak oil prices and high U.K. taxation, a lobby representing about 500 companies including the biggest energy companies said Feb. 24 in an annual survey of members.

The current rate of exploration drilling is the lowest since 1965, Oil & Gas UK said in its Activity Survey 2015. Cash flows for North Sea operators were a negative 5.3 billion pounds (US$8 billion) last year, the worst since the 1970s, as costs rose and revenues fell to a 16-year low, according to the report.

15,000 Jobs

“I think 15,000 jobs will go in the next few months, before the end of summer,” Wood, who has been involved in oil and gas for at least four decades, said in an interview Tuesday.

“There will be significant negative impact on the economy of Aberdeen,” he said by phone from the Scottish city. “It’s going to have a tough time as it depends on one industry, which is oil, and as the industry winds down in the medium term, in the next 20, 30, 40 years, it’s getting some taste of that.”

Companies looking to cut back include Total, which said Feb. 12 it will reduce investment in mature North Sea fields. Shell, starting to exit the Brent oil and gas field after it exhausted reserves, will begin a consultation this month on plans to dismantle one of its four platforms in the area.

Talisman Energy Inc. (NYSE, TSE: TLM), Marathon Oil Corp. (NYSE: MRO) and Apache Corp. (NYSE: APA) are also cutting back, according to Willie Wallace, Unite’s regional officer for offshore contractors.

Castlen Kennedy, a spokeswoman at Apache, said most areas affected by the 5% reduction in its global workforce announced in January are in the U.S. Lee Warren, a spokeswoman at Marathon, also said the majority of its cuts were in America. Press officials for Talisman-Sinopec in Aberdeen didn’t immediately return an e-mail and phone call seeking comment.

Sending Signal

If there’s one thing that unites managers and unions, it’s that the Conservative-led coalition government needs to help.

Actual job losses, which are “extraordinarily difficult to estimate,” depend partly on the signal that the administration sends to companies it needs to invest in the region, Wood said.

Chancellor of the Exchequer George Osborne will make the case in his annual budget on March 18. He’s certain to bring in basin-wide field allowances to spur investment, lowering the tax take on the industry to just below 50% from 60%, according to Wood, who says he isn’t privy to Treasury plans.

“That’s still too high though,” he said. “What is needed is a reduction in the headline or supplementary tax.

"The net effect should be below 40% to change the mind and mood of investment in the North Sea," said Wood, whose review of the industry a year ago, including policies to promote development, was accepted in full by the government.

The Treasury declined to comment specifically on its plans, refering to an earlier statement that Osborne had vowed to take further action.

While the proposed investment allowances won’t satisfy the immediate demands of the industry, unions or local politicians, it may at least mark a first step in helping prevent a stampede for the exit by investors that would be hard to reverse.

"If you have the right tax environment, then I believe in the medium to long term there are excellent prospects still," Fergus Ewing, Scottish government energy minister, said Feb. 5.
