API 90171

Provides detailed information on reported drilling activity, as well as estimates of the total number of wells and footage drilled for the current and recent quarters. The estimates of quarterly completions and footage are disaggregated by well type, depth interval, and quarter for the current year and two years prior. The data on reported drilling by date of completion includes well and footage data by quarter on a state and/or area basis. The reported drilling activity is also presented by depth interval. These tables show the cumulative number of well completions for the current year and two prior years. Separate tables are also provided by year for total wells, exploratory and development wells and new-field wildcat completions on a state and/or area basis. Reported completions by depth interval are given on an annual basis for the total United States, for exploratory wells, total U.S. onshore, and total U.S offshore. The report is available within two weeks following the end of a quarter.
