Is Scotland's oil industry still a good career option?

Oil made austere Aberdeen rich and the frigid North Sea port could not hide its wealth forever.

At first, straight out of Texas, the bars were filled with big hats, high heels and flash wheels.

Young men began to drive Porsches, their bosses bought Aston Martins.

The granite sparkled in the sunshine.

Sarah Browell-Hook, who grew up in the booming city says she took it all for granted.

"Everybody worked in the oil industry," she says.

Such success poured fuel onto the constitutional debate, especially the publication of secret government advice arguing that oil could bankroll an independent Scotland.

But nothing lasts forever. The average annual price of Brent crude - the North Sea benchmark - peaked in 2012 at $112 per barrel. By 2014, the year of Scotland's independence referendum, it had fallen to $99 per barrel.

The price then slumped to $52 in 2015 and $44 in 2016, a shock which led to mass redundancies in the North Sea - some 20,000 jobs lost between 2017 and 2018 alone - and a collapse in tax receipts for the UK Treasury.

"Everybody knew somebody who'd been made redundant and been affected," said Ms Browell-Hook, a 36-year-old mother-of-two who had never worked in the industry herself.

The slump prompted her to make a decision, to start a second career in decommissioning, dismantling the rigs and pipelines from which Aberdeen prospered.

"The oil boom and what it brought to my family was that my dad provided for his family comfortably and I guess the end of that journey, I'm hoping that the decommissioning side of things can help me provide for my family and for my children," she says.

The collapse in the oil price was a blow to the credibility of the Scottish government which, four months before the 2014 referendum, had predicted tax receipts in 2016/17 from oil and gas would be between £2.9bn and £7.8bn.

Actual tax receipts for 2016/17, which was to have been the first year of independence following a yes vote, amounted to just £36m having fallen well below zero in 2015/16.

Opponents of independence, who had prevailed in the referendum by 55% to 45%, said such dismal figures proved that a sovereign Scotland would have started life in crisis.

That was despite repeated assertions during the referendum campaign that oil was not the basis for independence - "it will be a bonus" insisted then First Minister Alex Salmond - but that position was later undermined by former Scottish National Party MSP Andrew Wilson when he chaired an SNP commission investigating the economics of independence.

"We did have oil baked into the numbers and it was indeed a basis," Mr Wilson told the BBC, as he recommended that any future prospectus for independence should not include the talismanic black gold.

Of course that was then and this is now but are we really at the end of the journey?

In Dyce, a suburb of Aberdeen, the Spider's Web is bustling. The pub sits next door to the city's heliport and is known as a waiting room for offshore workers.

It's nearly lunchtime and the place is busy with oilmen - they are all men - savouring their first beer after two or three weeks on the rigs.

There is a lot of talk of wives and girlfriends, of the balance between the reward of another pint and the risk of missing the train home.

Here views about the sustainability of the industry are mixed. One oil worker, who did not want to be identified, fretted about climate change and the need, as he saw it, to diversify away from fossil fuels for the good of the planet.

And yet there is still temptation below the waves.

A study published in October suggested there could be 17 billion barrels of oil (or the equivalent gas) still to be extracted by 2050, in addition to more than 43 billion barrels recovered since the 1970s.

Oil from BP's Clair Ridge development, west of Shetland, began to flow at the end of last year and the field is expected to remain productive for the next four decades while the energy firm Total recently announced a major gas discovery in the same region.

One drinker, Russell Edwards, 51, says for some people in the pub, decommissioning is a dirty word.

"They are finding more fields," he says. "Exploration is becoming more sophisticated."

He hopes the industry will see him to retirement but as for someone starting out now, "who knows?"

Confidence is to be found, as so often, behind the bar where Lauren Grant, 23, is pulling pints. She has worked at the Spider's Web for five years but now she is heading offshore herself, embarking on a career in oil exploration.

"I think there's a good bit more time in the North Sea," says Ms Grant. "I'm a local girl trying to get into our local industry."

After growing up in Dyce, watching the helicopters fussing to-and-fro, and studying geology at Aberdeen University, she is now about to take the plunge.

"Things are definitely on the up," she says.

And is she looking forward to stopping off in the Spider's Web for a pint when she comes ashore?

"Absolutely," she says, "can't wait."
