[LONDON] Most major conventional oil projects are at risk of cancellation or deferral if global prices remain at US$50 a barrel, consultancy Wood Mackenzie said in a report on Wednesday.
Global upstream and exploration spending has already dropped by more than US$1 trillion since the start of the oil price slump in mid-2014, the consultancy previously found, as cash-strapped oil companies tightened their purses.
Wood Mackenzie, which publishes regular assessments of the economics of the world's oil and gas fields, said especially deepwater projects offshore west Africa and in non-Opec nations won't make any money at the current market price of US$50 a barrel.
"In conventional oil projects, deepwater west Africa is a tough place to be. A number of projects in Angola and in Nigeria have been pushed out of our analysis," Simon Flowers, Wood Mackenzie's chief analyst, told Reuters.
Angola's state oil company Sonangol has suspended all talks relating to assets sales and in Nigeria, the government has warned about using funds set aside for oil projects to fill budget shortfalls.
Nevertheless Wood Mackenzie's analysis showed that aggressive cost cutting had increased the percentage of projects viable below US$60 a barrel to 70 per cent, up from 50 per cent a year ago.
Reductions of around 15 per cent in global oil service costs, including payments for drilling rigs or personnel, have helped boost some project economics, especially in the US tight oil market, the report said.
As much as 9 million barrels per day (bpd) of potential fresh oil supply is currently commercially viable at an oil price of US$60 a barrel, compared with 7 million bpd in the previous study.
"You will begin to see more FIDs (final investment decisions) come through by the end of this year and early 2017,"said Flowers, adding that US tight oil and near field projects will be targeted as they are cheaper to bring on stream.
