DUC well inventory by basin
Compare drilled-but-uncompleted well counts using each basin's reported period. Older series and unavailable basins are shown separately so your model uses comparable observations.

Basin series available, including older observations
The displayed subtotal includes only basins sharing the latest available reporting period; it is not a complete US total. Source coverage varies by basin. Some legacy EIA Drilling Productivity Report series remain historical; always check the period and source returned for your basin.

Use DUC inventory in a supply model
A DUC well has been drilled but has not yet been completed for production. Compare a basin's counts across matching reporting months, then combine them with completion activity. Do not infer a monthly change from a single observation or add frozen series to newer periods.
Open a basin to inspect its history. Confirm the source, available months, and account entitlement before scheduling an API integration.
