February 26, 2017: I've always considered the Charlson oil field one of the better fields in the Bakken, but the field is not even on the top 20 list for a) overall production; or, b) production/well.
Original Post
Remember: regardless of the size of the drilling unit, or the length of the horizontal, operators are targeting wells with EURs of at least 500,000 bbls of oil these days.
This is pretty cool.
In a 640-acre laydown drilling unit, Petro-Hunt is looking to place five horizontal Bakken pool (middle Bakken or Three Forks) wells.
From the March, 2017, hearing dockets:
- Case #25671 (not a permit, but a hearing case number), Petro-Hunt, Charlson-Bakken, four wells on a laydown 640-acre unit; S/2 of sections 35/36-154-95; six wells on an overlapping 1280-acre unit; McKenzie County
Petro-Hunt is looking to have as many as five wells in that 640-acre drilling unit outlined in red. The producing well in that drilling unit (#16963) has produced over 700,000 bbls in less than ten years and is still going strong. It will be interesting to look at the production profile of this well when four more wells are "squeezed" into this small drilling unit.
Note the dual lateral that was drilled back in 2008:
16963: note the two laterals going off in different directions; one lateral fracked with 580,578 lbs of sand; the other lateral fracked with 470,943 lbs of sand.

- The production profile for the first two years, pretty impressive:

Look how long that well produced at a rate over 10,000 bbls/month with minimal amount of proppant.
The well had a "slow" decline rate and still produces over 3,000 bbls of oil each month.
