Re-posting. This is mostly for newbies. Earlier today I posted:
Shale bust redux.I don't know if the Permian is different than the Bakken when it comes to fracking, re-working, mini-fracks, halo effect, advantaged oil, major re-fracks, etc., but I think the jury is still out with regard to the thesis that Elliott and Matthews would suggest. Below is not an atypical example of what is going on in the Bakken.
For those who subscribe to The WSJ, you probably saw the "as shale wells age, gap between forecasts and performance grows" by Rebecca Elliott and Christopher M. Matthews. If the story sounds familiar, it's because it is. This this has been previously posted. From the same writers, almost exactly one year ago, January 2, 2019, also in The WSJ, "fracking's secret problem -- oil wells aren't producing as much as forecast." And then again, September 29, 2019, by the same two writers, RE and CMM, "shale boom is slowing just when the world needs oil most." Really? Two final nominees for the Geico Rock Award for 2019.
In the data below, note:
- from the original completion date, 6/08, to 5/18, ten years, this well produced 123,000 bbls of crude oil;
- then after the re-frack in early, 2018, the cumulative by 10/19, had jumped to 471,000 bbls of crude oil
- this well, after a re-frack -- and a well that could have easily been written off, abandoned, and plugged -- came roaring back to produce 348,000 bbls of crude oil between in about eighteen months, and with oil about $20/bbl higher -- and the only cost -- the cost of fracking -- at a time when service costs and sand are at record lows
