U.S. crude oil and natural gas production increased in 2018, with 10% fewer wells 2/3/2020 WASHINGTON - In 2018, while production was increasing, the total number of wells producing crude oil and natural gas in the United States fell to 982,000, down from a peak of 1,035,000 wells in 2014. This increase in production, despite the decline in the number of wells, reflects advances in technology and drilling techniques. The U.S. Energy Information Administration (EIA)’s updated U.S. Oil and Natural...
