As tight oil operators focus on navigating the next few months, holding decades of well inventory simply isn't as important. The higher priority is cash flow. Any new wells must pay back incredibly fast. Screening by these metrics reshuffles the cost stack, and the Permian loses some of its luster. On a straight payback metric at today's prices, core zip codes in the Eagle Ford and Bakken represent some of the most competitive acreage in the Lower 48. More mature tight oil basins won't provide years and years of growth potential but can offer portfolio optionality and a safer retreat while prices remain depressed.
