Aramco is cleanest supplier of oil to China, US research finds

HOUSTON: Saudi Aramco supplies the environmentally cleanest oil to China, the biggest energy consumer in the world, according to a recent scientific study.
A research paper by Nature Energy, a publication of Stanford University in the US, compared the greenhouse gas (GHG) emissions from 13 big oil producers that shipped crude oil to China.
The results showed that Saudi crude had the lowest average carbon intensity when processed and used by Chinese industry, meaning that it produced fewer environmentally harmful emissions than other suppliers.
Venezuela sold China the “dirtiest” oil, according to the study, followed by Iran and Iraq, the researchers found.
Oil industry experts said that the findings reflect not only the higher quality of Saudi crude, but also the efficiency of the technology used to get the crude from reservoirs to shipment.
The study was highlighted at the CERAWeek by IHS Markit event in Houston, Texas. Amin Nasser, chief executive of Saudi Aramco, said: “Not all crudes are equal, and (the research shows that) Saudi Arabia has among the lowest carbon intensities of crude production in the world.”
The researchers said: “Oilfields in Saudi Arabia showed the lowest average GHG intensities due to highly productive reservoirs (high productivity index), low water production (leads to lower mass lifted and less energy expenditure in separation per unit of oil extracted) and low flaring rates.”
Ahmad Al-Khowaiter, Aramco’s chief technology officer, said that the findings showed the value of the big research and development program that the Saudi national oil company has made one of its main business priorities.
“It is good business, not just good environmental practice. We are the lowest cost producer, and the lowest emissions producer. It will help achieve sustainability through greater energy efficiency,” he said.
China is the biggest oil consumer in the world, but is also a major environmental polluter, mainly because it continues to use local coal as its main energy source.
The CERAWeek event has sought to understand the country’s new attitude toward the environment, dubbed “making China skies blue again” by the government.
Mikael Höök, an energy scientist at Sweden’s Uppsala University, said: “Documenting the emissions and net energy of a crude supply could be essential to meeting national emission and energy security targets.
“The data presented by Nature Energy indicates that the impact of replacing or phasing out just the most carbon-intensive 10 percent of Chinese oil imports could be significant — not just for continuing climate-informed energy strategies but also for geopolitical and energy security reasons, such as avoiding potentially risky suppliers in regions with security concerns.
“Improved understanding of Chinese oil policies and import preferences are, therefore, vital for modeling emission trends on local and global scales with a nuance that can inform policy realistically,” he said.


‘No sign of waning appetite for oil’

‘No sign of waning appetite for oil’

  • Oil is so entrenched in the modern world that demand is still rising by up to 1.5 percent a year
  • Of the almost 100 million barrels of oil consumed daily, more than 60 million bpd is used for transport

LONDON: Global oil consumption will reach 100 million barrels per day (bpd) — more than double the level of 50 years ago — in months, according to an industry report by Reuters.
Despite overwhelming evidence of carbon-fueled climate change and billions in subsidies for alternative technologies such as wind and solar power, oil is so entrenched in the modern world that demand is still rising by up to 1.5 percent a year, said the report.
There is no consensus on when world oil demand will peak but much depends on how governments respond to global warming, according the International Energy Agency (IEA), which advises Western economies on energy policy.
OPEC Secretary-General Mohammed Barkindo told a conference in South Africa on Sept. 5 that global consumption would hit 100 million bpd this year, sooner than anyone had expected.
With a sophisticated global infrastructure for extraction, refining and distribution, oil produces such a powerful burst of energy that it is invaluable for some forms of transport such as aircraft.
Of the almost 100 million barrels of oil consumed daily, more than 60 million bpd is used for transport. Alternative fuel systems such as battery-powered electric cars still have little market share.
Much of the remaining oil is used to make plastics by a petrochemicals industry that has few alternative feedstocks.
Although government pressure to limit the use of hydrocarbons such as oil, gas and coal is increasing, few analysts believe oil demand will decrease in the next decade.
If the current mix of policies continues, the IEA expects world oil demand to rise for at least the next 20 years, heading for 125 million bpd around the middle of the century.
