Prudhoe Bay Oil Field

Prudhoe Bay Oil Field is a large oil field on Alaska's North Slope. It is the largest oil field in North America, covering 213,543 acres and originally containing approximately 25 billion barrels of oil. The amount of recoverable oil in the field is more than double that of the next largest field in the United States by acreage, while the largest by reserves is the Permian Basin. The field was operated by BP; partners were ExxonMobil and ConocoPhillips until August 2019; when BP sold all its Alaska assets to Hilcorp.
