In the last decade, the U.S. has significantly increased its oil production, primarily due to advancements in hydraulic fracturing and horizontal drilling techniques. The country surpassed traditional leaders like Saudi Arabia and Russia, making it the top oil producer. As of 2023, the U.S. produces approximately 11-12 million barrels of oil per day. The oil produced in the U.S. helps meet both domestic and international demand, greatly influencing global oil prices and supply dynamics.
