The largest oil field in the world, Saudi Aramco’s Ghawar field, reached a production capacity of around 58 billion barrels of oil equivalent (boe) in combined reserves and 48.3 billion in liquid reserves, Aramco said in its bond prospectus, Reuters reported in April 1.

The company expects that the crude oil prices might remain unstable, especially after the recent months fluctuations.

“Fluctuations in the price at which the company is able to sell crude oil could cause the company’s results of operations and cash flow to vary significantly,” Aramco said.
