Random Update Of A CLR Antelope Well In Elm Tree Oil Field -- April 27, 2017

This well has been added to the "monster well" page and to the "wells of interest" blog.
  • 21488, 1,357, CLR, Antelope 3-23H, Elm Tree, Three Forks, 29 stages, 2.8 million lbs, t8/12; cum 532K 2/17;
Note to newbies: I have no specific criteria for "monster wells." I started the "monster well" page early in the boom when EURs for middle Bakken wells were expected to be around 350,000 bbls of oil. I thought, at the time, then, any well that was on its way to 500,000 bbls in three or four years could be considered a monster well.

Now, just a few years later, some operators won't drill a Bakken well if the likely EUR is not at least 750,000 bbls of crude oil.

Some (probably most) readers will feel that many of the wells on the "monster well" page (linked above) are not really "monster wells." That's fine. I follow them there for other reasons also.

Maybe some day I will add a page for super-monster wells -- wells that go over 1 million bbls, and then the super-duper monster wells, those that go over 2 million bbls.

It is my expectation that any given Bakken well is likely to be producing for 30 years. During that time, primary production from any given Bakken well will be affected by re-working the well; re-fracking the well; re-entering the well for additional side-tracks; activity from neighboring wells; as well as other factors. The general consensus is that 50 - 70% of a Bakken well's EUR will be produced in the first couple of years after being completed. I'm not convinced. I think the Bakken still has many surprises.
