Royal Dutch Shell and other world’s leading oil companies have published a bumper crop in profits last year as rising crude prices helped turn their fortunes around.

Shell’s net profit in 4th Quarter tripled in 2017 from $1.8 billion to $4.3 billion. The full-year net profit, came in at $15.8 billion in 2017 — an increase of 119 percent from the year earlier.

ExxonMobil, Chevron, BP, Royal Dutch Shell and Total also reported similar rising profits.

French giant Total saw its bottom line jump by more than a third, ExxonMobil’s fourth-quarter earnings rose nearly five-fold, Norway’s Statoil swung back into the black and BP’s profits soared.

In fact, “2017 was one of the strongest years in BP’s recent history,” the British group’s chief executive Bob Dudley told his annual earnings news conference.

Key to this success was the steady rise in crude prices in recent months, driven by a landmark deal between oil-producing countries both inside and outside the OPEC cartel to reduce the worldwide glut in supply by throttling output.

Correspondingly, after falling from $115 per barrel in 2014 to under $35 at the start of 2016, oil prices have been rising, from an average $44 in 2016 to $54 in 2017 to nearly $70 this month.

Flush with their new-found profits, the oil majors have raised dividends and announced share buy-back programmes, eager to make it up to their shareholders who have become restive after having to do with meagre payouts for years.

But it’s still a far shot from the heady days of old.

Companies have learned to live with low oil prices, slashing costs and investment to become leaner and fitter, and said they have little intention of abandoning that regime any time soon.

Shell’s CEO Ben van Beurden said he now always works on the assumption that oil prices would remain “lower forever”.

“We’re sticking to the cost-cutting programmes, despite the rise in crude prices,” said Total chief executive Patrick Pouyanne.

Such prudence is evident in the only modest uptick in investment in upstream exploration and production activities.

Globally, these investments rose by four percent to $389 billion last year and should increase by a modest two-to-six percent again this year, according to estimates published by IFP Energies Nouvelles this week.

By comparison, the amount totalled $683 billion in 2014.

Developments vary from region to region, and the anticipated growth this year is driven almost entirely by independent companies and US shale firms, whose overheads are much lower.

The majors, for their part, expect to cut investment in exploration and production by 16 percent this year.

“There’s been a sigh of relief across the boardrooms of the global oil and gas companies as higher prices have boosted results significantly,” said David Elmes, energy specialist at the Warwick Business School.

“But there’s also a hesitancy and uncertainty about the longer term which is tempering any return to full speed ahead,” he said.

Companies are holding back because oil prices look set to remain volatile and vulnerable to fluctuation.

Demand for oil from energy-hungry economies, such as China and India, is expected to remain robust. But the market’s much-needed rebalancing could be jeopardised by increased production by US shale companies.

“I’m certain that US independents will again invest a lot to profit from a price of $60 per barrel and ramp up shale production, so the market is going to remain volatile,” said Total’s Pouyanne.
