Oil prices have surged after several of the world's largest exporters announced surprise cuts in production.
The price of Brent crude oil is trading above $84 a barrel after jumping by more than 5%.
The increase came after Saudi Arabia, Iraq and several Gulf states said on Sunday they were cutting output by more than one million barrels of oil a day.
In addition, Russia said it will extend its cut of half a million barrels per day until the end of the year. บาคาร่าสูตร
