📋 Permit Cycle Assessment
The well file contains direct regulatory conditioning tied to the permit approval: (1) Commission Order 33459 establishes the 1920-acre spacing unit and setback requirements (150' N/S, 500' W) that govern bottomhole location; (2) the wet shoe completion design is explicitly stated as the basis for the tighter north setback; (3) NDAC 43-02-03-28 (simultaneous operations) is incorporated as a compliance obligation; and (4) the open hole log waiver (approved 12/03/2024) predates spud (04/07/2025) and directly justifies the logging plan waiver. However, no document explicitly states the original permit approval date or detailed technical justification for the specific horizontal trajectory and lateral length (26,353' MD). The geological report and anticollision analysis are post-spud (dated April 2025 operations). The permit itself does not contain an explicit approval date stamp; the dirt work date is listed as 03/08/2025, suggesting approval occurred before that date, but no contemporaneous approval order or permit letter is present in the file excerpt provided.
🔍 Permit Cycle Signals (5)
📄 Form 4 Sundry Notice (Form ID: 220209)
📅 12/03/2024 (Exact confidence)
NDIC approved waiver of open hole log requirement under NDAC 43-02-03-31 based on offset well (Vuki 5502 42-7H within 1 mile) with sufficient open logs to establish formation tops. Only GR-CBL to run from TD to ground level.
📄 Permit (Form ID: 289559, page 1 of 10)
📅 Unknown (Missing confidence)
Permit stipulation anchors approval to specific geometric setback constraints (150' north/south, 500' west boundary) tied to the 1920-acre spacing unit and intermediate casing cemented in lateral with wet shoe configuration. Squires-Bakken Pool defined as 50 ft above Bakken top to above Birdbear top.
📄 Permit Stipulations (page 1); Completion Design Detail Sheet (page in file)
📅 Unknown (Missing confidence)
North setback of 150' is expressly conditioned on production liner cemented in lateral with wet shoe configuration and ability to frac out shoe. This non-standard completion geometry justifies the tighter setback than standard 500' rule.
📄 Permit Stipulations (page 1)
📅 Unknown (Missing confidence)
Operator required to consider simultaneous operations rule (no boiler/generator/treater closer than 150' to producing well; 125' allowed with spark arrestor). Confirms multi-well pad operational constraint.
📄 Permit Review Policy (page 1)
📅 Unknown (Missing confidence)
Routine environmental condition for drilling operations; reflects NDIC Permit Review Policy.
📖 Historical Context (5)
Four-Well Pad Configuration (Cyclone 5502 11-17 2B, 3B, 4B) + Offset Well (Cyclone 5502 11-17 1A) planned
📄 Well Location Plat (S-1a, S-1b); Anticollision Report · 📅 Planning: 08/06/2024 (survey draft date)
Multi-well pad geometry and offset well operations constrain future drilling sequence and simultaneous operations. Anticollision analysis shows minimum separations to offset wells (e.g., Maridoe 5502 11-17 2B: 74.95 ft separation) that persist through lateral section and condition execution risk.
Sidetrack at 19,290' MD Required During Drilling – Upper Bakken Shale Encounter
📄 Geological Summary (Core Geologic Report, page 5); Sample Descriptions (page 15) · 📅 04/14/2025
Well encountered Upper Bakken Shale (UBS) at ~19,881' MD (April 14, 2025, 1726 hrs), requiring sidetrack ST1 at 19,290' MD. Total depth revised upward to 26,353' MD on ST1. This subsurface control (stratigraphic dip and facies geometry) is fundamental to future drilling decisions on sibling wells (3B, 4B) from same pad and affects landing zone precision and risk profile.
Surface Use Agreement (SUA) – Multi-Spacing Unit Drilling Authorization
📄 Affidavit Affirming Signed Surface Use Agreement (dated 11/12/2024) · 📅 11/12/2024
SUA confirms operator (Oasis) authority to drill from Section 17 surface location into off-lease spacing units (Sections 5, 8, 32 of adjacent townships). This landowner authorization is a prerequisite for continued operations and remains binding through completion and any future workover.
Cores and Samples Submission Mandate – State Geologist Letter
📄 Letter from Ross Edison, Geologist, NDIC (dated 12/9/2024) · 📅 12/09/2024
Regulatory obligation to submit all cores and samples to ND Geological Survey within 30 days of drilling completion (samples) and 180 days (cores). Sample collection intervals: 30' (vertical/build), 200' (horizontal). Non-compliance carries civil penalty up to $12,500/day. This obligation persists and affects well file closure and operational scheduling.
Filter Container Requirement – On-Site Waste Management
📄 NDIC Letter dated 08/28/2023 (Filter Socks and Other Filter Media) · 📅 06/01/2014 (effective date cited); 08/28/2023 (letter date)
Leakproof, covered filter container required on-site during drilling, completion, and flowback operations. Operator must ensure proper disposal of filters via authorized facility. Non-compliance enforces via NDAC 43-02-03-19.2 waste disposal mandate and ND Department of Health Division of Waste Management permit requirement.
🔧 Operator Pattern
Multi-well pad development strategy with coordinated horizontal drilling in tight spacing and simultaneous operations management; demonstrates subsurface control via offset well data and geosteering; executes non-standard completion geometry (wet shoe) to optimize lateral placement within restricted setback boundaries.
Cyclone 5502 11-17 pad contains three planned wells (2B, 3B, 4B) drilled from single surface location; anticollision analysis shows separation management to multiple offsets (Maridoe, Streamsong, Odin-Jorgenson, SAM wells); geological steering services (Core Geologic LLC) embedded in drilling; sidetrack executed operationally in response to formation dip and UBS encounter (April 14, 2025); affidavit confirms Surface Use Agreement for off-lease drilling authority.
Confidence: Medium
File contains strong technical justification for permit-cycle signals (open hole waiver, setback/spacing unit definition, wet shoe design) but lacks an explicit permit approval letter with signature date and approving engineer/geologist. Spud notification (04/07/2025) is confirmed, but original permit issuance date and formal approval order are not clearly marked in the provided excerpts. Geological report and anticollision analysis are post-spud (April 2025 operations), providing historical context rather than pre-permit justification. The 'dirt work date' of 03/08/2025 suggests approval before that date, but the exact approval authority and date remain inferred rather than documented in the file extract.
