extracts:
The logic behind the treadmill analogy is simple.
US shale producers can bring an oil well into production in a short amount of time, but the parabolic decline curve makes it so that year 1 of production declines on average over ~70% from peak to trough.
As US shale oil production grows, the base of the production grows. The faster the growth, the steeper the decline.......
And as US shale continues to grow, more and more capex has to go into replacing the decline. So the speed of the treadmill is the existing decline. Eventually, as the decline curves catch up, almost all of the spending each year will go towards replacing the decline. We estimate the year for that is 2023 for the Permian, 2020 for Bakken, and 2021 for the Eagle Ford......
The issue is that to complete more wells, you need to spend more capex. And to spend more capex, you need to spend outside of your cash flow. This requires shale producers to access the capital market, which is no longer available even for the leanest of producers. In addition, investor pressure on disciplined capex spending means less capex, not more.
This combined with the increasing treadmill effect will be the ultimate drag on US shale production. This doesn't mean US shale production won't grow this year, but it means that when it does stop growing, it will do it in a blink of an eye and catch the world off guard.
