Estimated total U.S. oil and natural gas well completions fell by 51 percent in the fourth quarter of 2015 compared to year-ago levels, according to API’s 2015 Quarterly Well Completion Report, Fourth Quarter.

“Our growth as a global energy superpower has been a game-changer for U.S. energy security while making energy cheaper for American consumers,” said Hazem Arafa, director of API’s statistics department. “We can’t expect that growth to continue if our own outdated energy polices stand in the way. Reducing unnecessary regulations and speeding up permitting on federal lands will help U.S. producers to compete effectively in the global market under the low-price environment.”

Estimated development oil well completions in 2015 fourth quarter fell 55 percent compared to 2014 fourth quarter estimates. Estimated development gas completions decreased 37 percent over the same period.
