Russia’s energy ministry said on Friday it is continuing close cooperation with Saudi Arabia and the Organization of the Petroleum Exporting Countries (OPEC) and non-OPEC oil producers to enhance market stability and predictability.
The statement came a day after Igor Sechin, CEO of Russian oil producer, Rosneft , said the September attacks on Saudi oil assets created doubts over its reliability as a supplier. The attacks temporarily shut down around half of the kingdom’s oil output.
“(Russian) oil companies have wanted to get busy stealing oil market share from the Saudis and others for a few years now but … Moscow has them in a bit of a box and is driving the bus,” said Greg McKenna, strategist at McKenna Macro.
OPEC+, an alliance of OPEC members and other major producers including Russia, has since January implemented a deal to cut output by 1.2 million bpd to support the market.
The pact runs to March 2020 and the producers meet to review policy on Dec. 5-6.
Prices were also supported by a statement from the United States and China that they are close to finalizing some parts of a trade agreement after high level discussions.
Elsewhere, a suggestion by U.S. President Donald Trump that Exxon Mobil or another U.S. oil company could operate Syrian oil fields drew rebukes from legal and energy experts.
