US shale operators have accumulated an estimated 3,900 drilled but uncompleted (DUC) horizontal oil wells with more than 90% in major liquids plays, said Rystad Energy’s latest analysis.
DUC numbers have grown during the current oil price slump. The DUC inventory includes wells with varying production expectations. Given differences among companies, the pace of DUC conversions will vary by operator, analysts have said.
Rystad Energy, an independent oil and gas consultant, maintains a shale well database called NASWellCube, which includes the DUC inventory.
