DUCs are
drilled but
un
completed wells. Drillers sink a hole first and then return later to “complete” the well by fracking it and connecting it to sales. An increase in DUCs means more new drilling is happening. A decrease in DUCs means fewer new wells are drilled while previously drilled wells are completed. According to a report by Enverus, some drillers have entered 2025 with substantially fewer DUCs than last year, creating potential effects on capital efficiency and production. Nearly every shale play, including the Marcellus/Utica, has seen DUCs fall. In some cases, by the hundreds.
