The US Department of Interior (DoI) will reverse a decision that allowed leasing and development in the National Petroleum Reserve in Alaska (NPR-A). The previous administration had approved plans to allow oil leasing and development in more than 80% percent of the 23-million-acre (9.3-million-hectare) reserve. The last NPR-A lease sale was held by the BLM in 2019. In August 2021, a US District Court Judge cancelled federal permits for ConocoPhillips’s Willow oil project in the National Petroleum Reserve in Alaska, citing issues with environmental analysis; the project could produce up to 160,000 bbl/d, with a processing capacity of 200,000 bbl/d over the next 30 years, producing a total of 590 mbl of oil and offsetting the declining production from the North Slope oil fields.
