📋 Permit Cycle Assessment
The well file contains contemporaneous regulatory documents justifying the Open Hole Log Waiver approval (05/16/2025) that directly conditions the permit. The waiver references offset well Thorlaksen 11-14H within one mile and stipulates substitute logs (GR-CBL, CBL, mudlogs). The permit itself derives from an earlier APD filed in December 2018 under Liberty Resources (later assigned to Silver Hill Energy Operating via well name change 02/10/2025) and renewed 02/13/2025. Mudlogging services from Terra Guidance (09/13–09/22/2025) and MWD survey certification (10/03/2025) provide post-drilling evidence of actual well construction execution within the permitted window. However, the file does not contain a direct permit approval letter dated to the recent 2025 operations; rather, it contains the 2019 drilling permit (Liberty Resources version) and subsequent administrative renewals/waivers. The most recent substantive permit approval is the 05/16/2025 open-hole log waiver (Form 4). The well was spud 08/25/2025 and reached TD 09/22/2025 under this regulatory framework. No major non-routine conditions or deviations from the permitted directional plan are documented; the well landed in Middle Bakken as planned.
🔍 Permit Cycle Signals (5)
📄 Sundry Form 247823; Drilling Permit dated 02/07/2019 (Liberty Resources version); Sundry Form 230404 (Silver Hill Energy approval 05/16/2025)
📅 05/16/2025 (Exact confidence)
Regulatory waiver from NDAC 43-02-03-31 logging requirement explicitly references offset correlation well and conditions substitute log delivery. This waiver directly conditions the permit approval and well execution.
📄 Sundry Form 230643
📅 02/10/2025 (Exact confidence)
Administrative designation change that establishes the legal well identity under which the current permit is issued. Required before permit renewal.
📄 Sundry Form 230404
📅 02/13/2025 (Exact confidence)
Renewed permit maintained operational continuity before spud on 08/25/2025. Permit expiration risk mitigation in permit cycle.
📄 MWD Survey Certification; Geologic End of Well Report dated September 22, 2025 (TD reached)
📅 10/03/2025 (Exact confidence)
Post-drilling survey documentation contemporaneously executed during well construction cycle. Establishes directional compliance and formation landing confirmation (Middle Bakken landed at 9,510 MD, 9/16/2025).
📄 Geologic End of Well Report; Well Sundry Form 247823 (open hole log waiver approval); sample submission noted to ND Geological Survey Core Library
📅 09/22/2025 (Exact confidence)
Mudlogging constitutes substitute documentation for open-hole logs per approved waiver. Middle Bakken lateral peak gas 2,469 units at 24,332 MD documented; provides formation confirmation without conventional open-hole suite.
📖 Historical Context (4)
Original permit issued February 7, 2019 (Liberty Resources Management Company, LLC) as Three Forks B1 target; well redesignated to Middle Bakken target under Silver Hill Energy Operating, LLC; target formation change reflects reservoir economics/portfolio shift
📄 February 7, 2019 Drilling Permit (Liberty Resources); Geologic Well Prognosis dated 12/2018; Well Name Change Sundry Form 230643 (February 10, 2025) · 📅 Unknown
Target formation change persists in the operating constraint set. Three Forks B1 was primary objective; Middle Bakken became active target. This reflects drilling priorities and regulatory compliance under the current operator (Silver Hill). Affects completion design expectations, frac staging, and production metrics going forward.
Setback requirements: 150 feet N/S, 1220 feet E/W from spacing unit boundaries (per Commission policy). Directional planning incorporated hard-line constraints at 7-inch casing point (170 FNL, 1810 FEL Sec 22) and bottom hole location (170 FSL, 1810 FEL Sec 34)
📄 February 7, 2019 Drilling Permit; Directional Planning Report dated 06/11/2018; Anticollision Report dated 06/11/2018 · 📅 Unknown
Setback compliance is permanent spacing unit boundary constraint. Wellbore geometry (KOP 8,714 MD, curve landing 9,510 MD, lateral TD 24,981 MD) was pre-engineered to honor these setbacks. Future well design, sidetrack authorization, or recompletions must respect the same boundary geometry and separation factors (minimum 37.17 separation factor vs. Thorlaksen 11-14H documented in anticollision report).
Closed-loop drilling system (no pit) mandated; cuttings disposal to approved facilities (Prairie Disposal, Indian Hills Disposal, Dishon Disposal listed); tank battery containment liner specified (felt-based layer + sprayed polyurethane); filtration containment container requirement per NDAC § 43-02-03-19.2
📄 Operator Statements for NDIC APD (Liberty Resources); Drilling Permit stipulations; NDIC Letter April 9, 2014 re: filtration containers · 📅 Unknown
Environmental and waste management obligations persist throughout well lifecycle. Closed-loop system, cuttings disposal routing, containment standards, and filter sock management are non-delegable operator responsibilities during completion, flowback, and production phases. Non-compliance exposes operator to civil penalties up to $12,500 per day per NDCC § 38-08-16.
Survey certification requirement: all directional surveys to be filed within 30 days of completion in TIFF and LAS digital format to certsurvey@nd.gov per NDAC § 43-02-03-25
📄 February 7, 2019 Drilling Permit (Liberty Resources); Drilling Provisions section · 📅 Unknown
Ongoing regulatory filing obligation. MWD survey was filed and certified 10/03/2025. Future recompletions, sidetracks, or pressure tests require certified survey documentation within 30-day window. Non-compliance may block subsequent well operations.
🔧 Operator Pattern
Operator transition from Liberty Resources Management Company, LLC (2018–2024) to Silver Hill Energy Operating, LLC (2025–present); administrative consolidation of permits and standardization of environmental/operational statements
Original APD filed 12/11/2018 by Liberty Resources (permit issued 02/07/2019); well name change approved 02/10/2025 transferring well to Silver Hill Energy Operating LLC designation; APD renewal filed by Silver Hill 02/05/2025 (approved 02/13/2025); open-hole log waiver and final operations (spud 08/25/2025, TD 09/22/2025) executed under Silver Hill Energy Operating, LLC. Operator statements (no diesel in hydraulic fracturing, gas capture compliance, closed-loop drilling, filtration containment) repeated across both operator iterations, indicating operational standardization. No adverse compliance events or permit violations documented in file.
Confidence: High
File contains complete contemporaneous regulatory approval chain for the most recent permit cycle (open-hole log waiver 05/16/2025, permit renewal 02/13/2025) with explicit NDIC reviewer signatures and effective dates. Mudlogging and directional survey data from drilling execution (08/25–09/22/2025) are contemporaneously documented with professional certifications. MWD survey certified post-drilling (10/03/2025). Formation landing (Middle Bakken at 9,510 MD TVD 9,169 feet, landed 09/16/2025) confirmed by both MWD and geologic logs. Directional compliance verified via anticollision analysis (minimum separation 37.17 against Thorlaksen 11-14H). No gaps in critical permits or material discrepancies between planned (December 2018 directional plan) and executed wellbore (September 2025 survey). Operator transition clearly documented via well name change sundry. Only minor ambiguity: recent permit approval letter specific to 2025 operations not explicitly in file, but waiver approval (05/16/2025) and renewal (02/13/2025) constitute active permits under which spud occurred.
