Increased oil and natural gas development in the Wolfcamp play has helped drive overall crude oil and natural gas production growth in the Permian Basin during the past decade. Drilling and completion operations within the Wolfcamp play have been responsible for much of the crude oil and natural gas production growth in the Permian Basin since 2007. As of September 2018, the Wolfcamp accounted for about 1 million barrels of crude oil per day (b/d) and 4 billion cubic feet of natural gas per day (Bcf/d). Crude oil production in the Wolfcamp accounts for nearly one-third of total Permian crude oil production and more than one-third of Permian natural gas production.
