Recent results out of the Permian, are mimicking the onset of a production plateau that has taken place at other, more mature U.S. shale plays. Oil production from the best 10% of wells drilled in the Delaware portion of the Permian was 15% lower last year, on average, than top 2017 wells, according to data from analytics firm FLOW Partners LLC. Meanwhile, the average well put out 6% less oil than the prior year, according to an analysis of data from analytics firm Novi Labs. Oil production in the U.S. rose from about 7.2 million barrels a day a decade ago to a high of about 13 million barrels a day before the pandemic. But domestic output last year grew at one-third of the annual average pace seen in shale’s heyday from 2017 to 2019, and hasn’t yet caught up with prepandemic levels. The slowdown was mostly because of investor pressure on companies to curtail spending and limit growth in favor of generating higher returns. At the same time, weaker well results in the Delaware basin contributed to flattening output.
