This is the first chance I've had to see Enno Peter's new work.

As one might expect, its simple, easy to read, concise and fast. No filtering to dark thirty to see what you want. This I recall was the mindset from the beginning of shaleprofile.com a decade or more ago...let the data do the speaking... think for yourself. No artificial intelligence necessary. I like that because I don't like kids who've never owned working interest, paid an LOE or an AFE telling me I need machines to explain to me what stuff means.

Here we see a type curve for oil rate vs. cumulative oil production for 60,000-some-odd wells in the Permian, per year. 2010-2015 is cached, thank you very much. Projected decline I suspect is spot on.

We know that Permian HZ wells decline sort on a modified hyperbolic basis, then bubble point arrives and liquids dive for the bottom on an exponential basis until they reach economic limits and need to be put out of their misery. There is no reason arguing what those economic limits are at various oil price scenarios, but I assure you, they cease making money on a full cycle basis way sooner than you think. Thirty-year DCA's may be standard in the engineering world but terminal decline rates of all tight oil and tight gas wells indicate at 20 years these wells become old men shuffling along in walkers, very gassy and leaking water, badly.

By the way, in the above chart we see that for Permian 2025-2026 wells had typical high IP30's, because of longer laterals, then start dying quicker than previous year's wells, the EUR implications lower. We've been talking about that for years; well, here you go. Quick and easy to read. Mikey likey.

Good luck Enno !
