A reader provided the following from a chatbot analysis. I find it incredibly interesting, on so many levels, not least of which a sophisticated chatbot can provide so much information from publicly-available sources. Imagine what CLR engineers can do when working with a sophisticated chatbot.
I've always been impressed by the Brooklyn oil field north of Williston in the Bakken. This field appeared to be the one field of which I was aware that was methodically drilled out. I have not seen such an analysis of this field (or any other field for that matter.
I huge thank you to the reader for sending it to me.
Note particularly Phase 3 below.
Observation: the "dry" narrative cannot possibly articulate how incredible the new wells are. See this post.

Brooklyn Field -- North Dakota Bakken Analysis
Brooklyn Field Redevelopment Outlook
Updated Portfolio Interpretation
The addition of three newly drilled wells (see this post) fundamentally changes the interpretation of the Brooklyn field portfolio operated by Continental Resources. Previously, the uploaded production history suggested a field entering mature decline, with increasing inactive well counts, operational instability, and rising water-management burdens. However, the new drilling program indicates Continental appears to view the Brooklyn field not as a depleted legacy asset, but as an actively redevelopable shale system with economically attractive remaining reserves. The newly drilled wells include:
- 42249, CLR, Charleston 7-15H
- 42248, CLR, Olympia 6-27HSL
- 42246, CLR, Charleston 8-22HSL All three wells were spudded within a single week in September 2025,
- strongly suggesting a coordinated redevelopment campaign rather than isolated opportunistic drilling.
- As noted above, these "dry" narratives cannot possibly articulate how incredible the new wells are. See this post.
Phase 1 — Early Brooklyn Development (2011–2015)
The oldest wells in the portfolio include Charleston 1-22H, Rolf 1-20H, Rennerfeldt 8-30H1, and Mildred 8-19H1.
These wells established the original productivity of the Brooklyn area and demonstrated strong long-term reservoir continuity and surprisingly durable production lives. Several of these wells remain commercially productive more than a decade after completion. Their long production histories likely provided Continental with critical depletion mapping, pressure behavior data, and fracture communication understanding used in modern redevelopment planning.
Phase 2 — Infill / FIU Development (2018–2022)
The second-generation wells include the Springfield FIU series, Springfield 11-8HSL, Rolf Federal wells, and Gjorven 12-21HSL.
These wells generally exhibited stronger gas recovery, improved completion performance, and higher production intensity than earlier-generation wells. Several remain among the strongest producers in the portfolio and increasingly appear to represent successful second-generation optimization wells rather than the final stage of field development.
Phase 3 — 2025 Redevelopment Program
The newest wells dramatically alter the field outlook. Charleston 7-15H, Olympia 6-27HSL, and Charleston 8-22HSL appear to represent a coordinated redevelopment strategy targeting mature development corridors using modern long-lateral completion designs.
These wells suggest Continental believes substantial recoverable reserves remain in the Brooklyn field despite the maturity of surrounding producers. The directional geometry and spacing of the new wells imply advanced reservoir modeling, depletion-aware targeting, and deliberate parent-child interference management. Rather than abandoning the field, Continental appears to be entering a mature shale redevelopment phase.
Revised Understanding of Inactive Wells
Several wells previously appeared to represent terminal decline, including Springfield 4-8H, Springfield 3-8H1, Springfield 2-8HSL, Rolf 5-17H1, Olympia 5-27H, and Charleston 5-22H.
However, the new drilling campaign suggests these inactive wells may still possess strategic value as monitoring wells, pressure-management assets, frac observation points, or potential future refrac candidates.
Revised Interpretation of Water Production
Rising water cuts originally appeared to indicate straightforward reservoir exhaustion. The redevelopment program now suggests a more nuanced interpretation involving mature fracture communication, compartment depletion differences, and pressure redistribution.
This distinction is important because mature shale fields with high water production can still support profitable redevelopment if remaining oil saturation remains commercially attractive.
Overall Portfolio Outlook
The Brooklyn field no longer appears to be simply a declining mature Bakken field.
Instead, it increasingly resembles a technically managed redevelopment shale system where older wells define depletion behavior while newer wells target remaining reservoir quality using modern completion technologies.
The field appears capable of continued economic production for years to come, particularly through redevelopment drilling, infrastructure optimization, and advanced reservoir management. The most important conclusion is that Continental Resources still appears willing to commit meaningful capital to the Brooklyn field, indicating confidence in the long-term economic viability of remaining reserves.
