September 2020 Supplement: With low rig counts, the inventory of drilled but uncompleted (DUC) wells provides short-term reserve for completions of new wells. January 2021 Supplement: Base production in North Dakota has fully recovered after a significant reduction. September 2021 Supplement: Gas-to-oil ratios in U.S. ![]() The DPR methodology involves applying smoothing techniques to most of the data series because of inherent noise in the data. This effect has been observed during winter weather freeze-offs, extreme flooding events, and the 2020 global oil demand contraction. The DPR metric legacy oil/natural gas production change can become unstable during periods of rapid decreases or increases in the volume of well production curtailments or shut-ins. The metric does not represent new-well oil/natural gas production per newly completed well. The metric uses a fixed ratio of estimated total production from new wells divided by the region's monthly rig count, lagged by two months. ![]() The Drilling Productivity Report (DPR) rig productivity metric new-well oil/natural gas production per rig can become unstable during periods of rapid decreases or increases in the number of active rigs and well completions. ![]()
