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. This effect has been observed during winter weather freeze-offs, extreme flooding events, and the 2020 global oil demand contraction. The DPR methodology involves applying smoothing techniques to most of the data series because of inherent noise in the data.
September 2021 Supplement: Gas-to-oil ratios in U.S. primary oil-producing regions.
January 2021 Supplement: Base production in North Dakota has fully recovered after a significant reduction.
September 2020 Supplement: With low rig counts, the inventory of drilled but uncompleted (DUC) wells provides short-term reserve for completions of new wells.
August 2020 Supplement: Rig counts fall but new-well production per rig rise as new-well production persists.
March 2020 Supplement: Base production accounts for a material share of total U.S. tight oil production.
