Of all the operators in the Bakken, Petro-Hunt seems to be off the radar scope.
Hold that thought.
There are a lot of great fields in the Bakken. It's impossible for me to come up with a top ten list. Some fields are hot for awhile, then activity slows down and another field becomes hot. Here are some of the fields that always get me excited:
- Elm Tree
- Banks
- Grail
- Stockyard Creek
- Reunion Bay
- Sanish
- Parshall
I was reminded of that when updating a 2560-acre drilling unit in the Charlson.
One of the wells:
- 16452, 265, Petro-Hunt, USA 14D-4-1H, Charlson, single section, t10/07; cum 374K 8/19;
- this well was drilled in the very first year of the Bakken boom, 2007
- this well is now twelve years old
- for such an old well, its cumulative production is mediocre at best -- but that's by today's standards; in 2007, EURs in the Bakken were pegged at 375,000 bbls; and guess what? that's exactly where this well is
- but then this:
- monthly production, after the dreaded Bakken decline, plateaued at around 3,000 bbls/month (which, by the way, is a nice well)
- last summer, the 11-year-old well was taken off line for three months to give it a breather (LOL)
- when it came back on line, production jumped 17,000 bbls/month -- a 5-fold increase in production
- but there's more: this was the production when this well was first drilled/completed:

The best this well did immediately after being completed, less than 8,000 bbls/month.
Then eleven years later, a jump in production from 3,000 bbls/month to 17,000 bbls/month.

From a sundry form dated November 26, 2007:
A 12 1/4" surface hole was drilled and 9 5/8" casing cemented without any problems.Frack data at time of original completion, back in 2007:
An 8 3/4" hole was then drilled to 10,266' MD and 7" casing was ran and cemented.
A 6" hole was then drilled to 15,456' MD and a 4 1/2" liner set and cemented from 10,003' to 10,673' with the remainder of it left open hole. A coiled tubing motor was stuck and lost in the lateral at 10,640'.
When it -- the coiled tubing motor -- couldn't be recovered, a bridge plug was set at 9,953', a window cut in the casing, and a curve built to intersect the old lateral.
Even though the 2nd lateral was drilled in the same direction, it failed to intersect the first lateral. The second lateral was drilled to 14,570' MD and a 4 1/2" liner was ran and cemented from 9,610' to 10,675'.
The well was completed [sic -- drilled to depth] but would not flow so it was sand fractured. It was placed on rod pumping unit 11-21-2007.
- open hole or perforated interval: 10,675' - 14,570'
- 72,360 lbs mesh sand
- 348,500 lbs mesh sand with 5,513 bbls of gelled water
(Some of the data below is a repeat from above.)

It was refracked from January 24, 2015, to January 26, 2015, according to FracFocus, with a very, very small completion: 1.3 million gallons of water; 88.9% water by mass; sand, 8.85% by mass.

It was taken off line for four months, summer of 2018, and this was the production when it came back on line; it was not re-fracked:

So, did you catch that. Petro-Hunt wasn't even going to frack this well. They drilled to depth. But the well would not flow. So, they pumped a bit of sand and a bit of water down the wellbore and they had a well.
There are some fields that seem particularly well-suited for re-fracks. The Charlson is one of them. Reunion Bay seems to be another.
By the way, look at this Petro-Hunt Charlson well, only three years old and trending toward one million bbls cumulative, and a very moderate frack:
- 28016, 912, Petro-Hunt, USA 153-95-22D-15-1HS, middle Bakken, 37 stages; 4.7 million lbs, Charlson, t11/15; cum 721K 8/19; huge well; still at 8,000 bbls/month, 8/19;
