The quote below contradicts the well by well work of Saputra etal where they show the cessation of drilling associated with a rapid cliff falloff, which is apparent from the high decline of existing production. As long as you keep drilling you can hold it up till the end. I know that is not how it is to end-stop drilling overnight, but I don't know why 28% depleted would trigger the rollover either. I made a post on the North Sea and that is about right for that play, a third of the 13,500 wells to date had been drilled when it rolled over.
Across all fields, our linearizations suggest that basins will roll over when approximately 28% of their reserves are produced. Our machine learning models show oil shales are now 28–32% depleted, while gas shales are 30–34% depleted. This points to a slowdown driven by depletion, not price or regulation.
Yeah, Jim; I didn't quite get that either. What's magic about 28%? I've seen 50%. And of what, exactly? I've seen URR of 35G, 80G even 140G in the Permian alone.
