Okay, let's go back to this one.
Disclaimer: in a long note like this there will be factual and typographical errors. I used poetic license to tell part of the story. If I stepped on any toes, let me know and I will make it all "right." It should be noted that one can buy soft drinks at J Dub's in Williston.
Disclaimer: I can't stress enough that there might be factual and typographical errors in this post. If this is important to you, go to the source. Hearsay at J Dub's is probably not "the source," but I bet you can get some pretty good stories.
I posted this graphic earlier as a stand-alone post with no narrative but said I would get back to it later.
I'm going to do this from memory. It would take too much time and effort to go back to get the details. So if this is wrong, and affects the story, let me know and I will correct it. As noted I used poetic license to tell part of the story. Don't take that part seriously.
It's just for fun.
The other night I was updating wells that were drilled in 2015.
I came across this completion report:
Wow, 81 stages! In two fracks: a 40-stage frack followed by a 41-stage frack. But then I remembered it was a Slawson well, and Slawson would never do anything so audacious as an 80+ stage frack. LOL. Nope, they did something more audacious.
Wow, the Bakken never ceases to amaze me.
So, when I saw that 81-stage frack done in two stages, it took me three seconds to take another look -- I think what jumped out at me was the fact that the target for the first frack was different than the target for the second frack.
At least one date in the geologist's drilling report was wrong (the "cease drilling date" was said to be before the spud date -- I'm pretty sure about that, but could be wrong). Other dates are probably correct, but I can't reconcile them. But, then, I can't reconcile a lot of things in the Bakken. See the sundry form below, and then compare the target/test date (circled in red) with the target/test date in the completion report above (also circled in red).
The dates may be correct, and I may be missing something but the dates don't matter for the story.
So, for #30412, Slawson drilled a typical long lateral into the upper bench of the Three Forks (TF1). MD was 10,771 feet (vertical before they went horizontal).
On a Sunday some months later, with April Fool's Day coming up, after a long night at J Dub's, the Lightning Federal site manager drives out to the pad, #30412, and suggests to the team, "hey, why not cut a window in the casing of the TF1 horizontal / kick-off point and drill the TF2?"
Nothing better to do, and something to impress the boss, that's exactly what they did. They cut a window in the TF1 casing at/near the kick-off point and drilled the TF2. MD was 10,793 feet, about 22 feet deeper.
That simply amazes me. The roughnecks drill down two miles deep into the earth and then cut a hole in the cement casing, and then hit another target, just 22 feet deeper. I don't know about you but for me that's as impressive as NASA landing a drone on an asteroid.
Maybe more impressive. After all, NASA doesn't need a permit or an environmental impact statement to land on an asteroid.
Some time later, the boss told the Lightning Federal site manager that he and the roughnecks were probably just lucky.
The site manager replied, "Here, hold my drink." The site manager then had the roughnecks do the same thing 105 feet to the east (distance between surface holes).
This time, MD for TF1 was 10,880 feet and the MD for TF2 was 10,906 feet, a difference of 26 feet.

When looking at the production data, be sure to note that the older middle Bakken well was a short lateral (one mile long) whereas the Three Forks wells were long laterals.
Look at the IPs for the long lateral TF wells compared to the old middle Bakken well and the newer long lateral middle Bakken well:

Finally, look at the monthly production for #30414, drilled back in 4/16 -- more than two years ago:
