That field is tracked here.
Some comments:
- production data for all wells completed in 2012 and before has been updated as of 11/19;
- many of the wells completed in 2014 and 2013 have also been updated
- there are at least a dozen wells in the Brooklyn oil field that have come off line since 9/19 and remain off line
- they could be coming off line because they are no longer economical; have served their purpose; and will soon be shut in, plugged, and abandoned; but I don't think so;
- more likely, the wells coming off line suggest there is new fracking activity in the Brooklyn oil field and these wells coming off line will soon be back on line
- there's lots of work left to be done in the Bakken
- "all" wells drilled before 2014 in the Brooklyn oil field will need to be re-fracked;
- by today's standards, the wells drilled in the Brooklyn in 2014 and before were mediocre wells at best
- the wells in the Brooklyn oil field now are huge; example below
- another Brooklyn well -- the first in a long time -- will be coming off the confidential list this next week
Compare that with this Brooklyn well still on the confidential list:
- 35563, conf, CLR, Gjorven 12-21HSL, Brooklyn, 107,981 bbls in less than four full months of production; 1.896 million cf natural gas (31,589 boe) or a total of 139,570 boe in less than four full months of production. Up until recently, the Brooklyn would have been considered Tier 2 at best, possibly Tier, but with these kinds of wells, certainly Tier 1:
| Date | Oil Runs | MCF Sold |

| 10-2019 | 44350 | 76587 |

Wells in the Brooklyn oil field:
- as of January 12, 2020, there are 142 wells permitted in the Brooklyn oil field
- 2xxx: 76
- 3xxx: 60
- A: 104
- IA: 6
- LOC: 6
- CONF: 7
- DUCs: 14
- PA: 1
- PNC: 2
- Dry: 2
- the following was done quickly
- it has not been double-checked or proofread
- there are a lot of assumptions
- I am inappropriately exuberant about the Bakken
- I often make typographical and content errors that need to be corrected
- I often make simply math errors that need to be corrected
- I assume there will still be a demand for oil two years from now
- 36 sections
- 6 x 6
- six miles by six miles = 36 square miles
- 36 section x 640 acres / section = 23,040 acres
- 23,040 acres / 142 permitted wells = 162 acres / well
- most sections with about 9 horizontals
- a few sections with as few as 3 horizontals
- most are still MBH wells
- there may be around 30 first bench Three Forks wells in all of Brooklyn oil field
- there will be at least four ways of tracking well density in Brooklyn oil field
- total acres / total permitted wells
- total acres / total active and producing wells
- total acres / wells per formation (middle Bakken, first bench Three Forks, etc)
- drilling units / wells per formation
- 36 section s = 18 sections (using the standard 1280-acre size drilling unit)
- 8 middle Bakken wells / 1280-acre unit
- 8 x 18 = 144 middle Bakken wells in the Brooklyn oil field
- I see approximately 16 sections with minimal drilling in the Brooklyn oil field = 8 sections (using standard 1280-acre size drilling unit)
- 8/18 = 44%
- projections, middle Bakken wells:
- high end: 144 x 1.50 = 216 potential middle Bakken locations at current spacing
- low end: 144 x 1.25 = 180 potential middle Bakken locations at current spacing
- 216 - 144 = 72 more middle Bakken wells in Brooklyn oil field at current spacing (high end)
- 180 - 144 = 36 more middle Bakken wells in Brooklyn oil field at current spacing (low end)
- the number of Three Forks, first bench wells, drilled so far in the Brooklyn field is relatively trivial
- projections, Three Forks, first bench wells:
- the number of Three Forks, first bench wells will eventually equal the number of middle Bakken wells (high end)
- the number of Three Forks, first bench wells will eventually equal half the number of middle Bakken wells (low end)
- potential Three Forks, first bench locations
- 216: high end
- 108: low end
- total wells yet to be drilled in the Brooklyn oil field at current spacing:
- 288 ( high end)
- 144 (low end)
- number of wells that need to be re-fracked (or re-drilled, same location): 125
- number of wells likely to be drilled/completed per year in the Brooklyn oil field: 12
- projections:
- 288 + 125 / 12 = 34 years of drilling / re-fracking
- 144 + 125 / 12 = 22 years of drilling / re-fracking
- bottom line: lots of work yet to be done in the Bakken
