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.


Iran says Japan has started process of importing Iranian oil

Iran says Japan has started process of importing Iranian oil

  • Exemptions have been granted to Iran's biggest oil clients - Japan, China, India, South Korea, Taiwan, Italy, Greece and Turkey
  • Iranian oil accounted for 5.3 percent of Japan's total crude imports in 2018

LONDON: Japan has started the process of importing Iranian oil, which was suspended due to U.S. sanctions, the governor of Iran's central bank said on Monday.
The resumption of oil imports comes after Tokyo was granted a waiver from U.S. sanctions that went into effect in November. Iran is the fourth-largest oil producer among the members of the Organization of the Petroleum Exporting Countries.
"After China, South Korea, India and Turkey, Japan also started the process of importing Iranian oil," Abdolnaser Hemmati was quoted as saying by the state news agency IRNA.
Iran's oil exports have fallen sharply since U.S. President Donald Trump said in May 2018 the United States would withdraw from a pact curtailing Iran's disputed nuclear programme and reimpose sanctions on Tehran.
However, exemptions have been granted to Iran's biggest oil clients - Japan, China, India, South Korea, Taiwan, Italy, Greece and Turkey - which allow them to import some oil for another 180 days.
Iranian oil accounted for 5.3 percent of Japan's total crude imports in 2018.
