Learning takes time and effort. But a good education pays off. North America’s oil industry has been in school for the past three years, studying how to become more productive in a fragile $50-a-barrel world. Many companies in the class of 2017 have graduated and are now competing hard for a greater share of global barrels. Having said that, North America’s education on how to make oilfields more productive appears to be stalling. After a breathtaking uphill sprint, productivity data from the U.S. Energy Information Agency (EIA) shows that the last few thousand oil wells in top-class American plays may have hit a limit—at least for now. Our Figure this week shows a classic S-curve learning pattern in the mother lode of all oil plays: the Permian Basin. Slow improvements to rig productivity (2012 to 2015) were followed by a steep period of rapid learning (2015 to 2017). Eventually […]
