Rystad Energy research firm expects U.S. to surpass Saudi Arabia’s title as world’s largest exporter of oil, natural gas liquids and petroleum products. Over the past decade, drilling innovation has increased shale oil production, and overall oil production in the U.S. has more than doubled in the last decade, which made the U.S. the world’s largest oil producer surpassing Saudi Arabia and Russia. Saudi Arabia’s daily exports of oil, gas, and petrochemical liquids are 9 million barrels, exceeding the U.S. by one million barrel, a gap that will probably vanish according to Rystad experts.
