📋 Permit Cycle Assessment

The permit approval dated 2025-04-08 (dirt work date) is directly conditioned and explained by five regulatory and technical signals. Three direct NDIC stipulations bind the approval: (1) conditional setback geometry tied to wet-shoe cemented lateral and fracturing capability (Order No. 32567); (2) Bull Butte-Bakken Pool definition establishing producibility boundaries; (3) closed mud system and shutoff device mandates. Two supporting technical submissions justify operational feasibility: (4) Open Hole Log Waiver approved 2025-05-15 based on nearby offset well data; (5) completed anti-collision study with documented separation factors (1.476–5.273 SF range) confirming safe geometric clearance from offset wellbores. The permit file demonstrates a coherent regulatory approval pathway. The spud date (2025-05-20) and subsequent geological/directional execution (logged through 2025-07-14 TD at 26,578 MD) align with the conditional framework established in the April 2025 approval. All contemporaneous documentation supports the permit's legal and technical sufficiency.

🔍 Permit Cycle Signals (5)

NDIC Field Order No. 32567 approval issued on explicit condition: approval granted conditional on all portions of wellbore not isolated by cement to maintain 150' setback from north/south boundaries and 500' setback from east/west boundaries within 1920-acre spacing unit (Sections 17, 20, 29, T156N, R102W)

This is a direct regulatory condition binding approval. The south setback is explicitly premised on production liner cemented in lateral with wet shoe and fracturing capability. Non-compliance with setback geometry voids the permit's legal foundation.

Bull Butte-Bakken Pool definition issued: accumulation of oil and gas from 50 feet above top of Bakken Formation to above top of Birdbear Formation

Non-routine operational constraints tied directly to permit approval. Closed mud system is environmental/compliance mandate; shutoff devices are safety requirement.

Open Hole Log Waiver approved under NDIC Rule 43-02-03-31 on basis of offset well Straw POW 5602 42-17 (NDIC File No. 28007) within one mile with sufficient open logs to establish formation tops; GR-CBL run from TD to ground level substitutes for full open hole logging

Regulatory waiver explicitly conditions the permit approval by substituting alternative logging protocol. The waiver is directly referenced to nearby offset well data, establishing a contemporaneous technical justification for non-standard operational procedure.

Anti-collision study completed with industry-standard 1.2 separation safety factor maintained in intermediate sections; surveys taken at 93–100 ft intervals increasing in frequency when approaching lateral crossings; gamma ray signatures used to identify existing wellbore locations in target zone

Pre-permit technical submission (dated pre-approval) that directly justifies well geometry approval. Separation factors documented for SOMERSET 5602 12-17H (1.476 SF) and Ellis offset wells (1.323–5.273 SF) confirm geometric feasibility and regulatory compliance pathway for the approved wellbore design.

📖 Historical Context (4)

Cores and samples collection requirement mandated by North Dakota Century Code Section 38-08-04: samples to be collected at 30' maximum intervals through vertical/build sections and 200' maximum intervals through horizontal sections, beginning at Base of Last Charles Salt; cores/samples to be delivered to ND Geological Survey Core Library within 30 days (samples) and 180 days (cores) of completion; violation subject to civil penalty up to $12,500 per offense per day
📄 Letter from ND Geological Survey dated 2025-01-27 to Dustin Anderson, Oasis Petroleum (RE: CORES AND SAMPLES, Well File No. 41543) · 📅 2025-01-27
This obligation persists beyond permit issuance and conditions post-drilling operations through completion. It is a regulatory obligation triggered by well spud (2025-05-20) and not satisfied until samples are submitted to the state core library. Failure to comply exposes operator to civil penalties. The requirement is a forward-operational constraint that must be executed during well abandonment/plugging phases.

Updated Production Facility Location Notification (Sundry Form, received 2025-03-27, Form ID: 238579): per APD stipulation, production flowlined to facility on different pad (not on Phoenix 5602 13-17 pad); flowline route diagram provided with distances (1,756' on Mortenson NE¼; 2,960' on State NW¼; 3,746' on State SW¼ of Section 16/17, T156N, R102W)
📄 SUNDRY FORM FOR WELL FILE NO.: 41543 FORM ID: 238579 (Supplemental Information - Submit Revised/Corrected Information) · 📅 2025-03-27
This notification establishes a facility consolidation obligation and right-of-way requirement across multiple landowner tracts (Dustin Mortenson, State of North Dakota) extending 1+ mile from the well pad. The flowline route and off-pad facility location condition operational execution during completion and production phases. Cross-landowner infrastructure dependencies and easement compliance remain active constraints through operations.

Filter socks and filter media leakproof container requirement (ND Administrative Code 43-02-03-19.2 and 33-20-02.1-01): on-site container mandated beginning at well spud and remaining on-site during clean-out, completion, and flow-back whenever filtration operations conducted; container must be leakproof, covered, and placarded; operator must have valid solid waste transportation permit from ND Department of Health Division of Waste Management
📄 Letter dated August 28, 2023, from ND DMR to operators (RE: Filter Socks and Other Filter Media—Leakproof Container Required, Oil and Gas Wells) · 📅 2023-08-28
This requirement applies to all wells spud after June 1, 2014, and obligates operator to maintain compliant waste containment and disposal infrastructure throughout drilling, completion, and flow-back phases. The obligation is continuous from spud date (2025-05-20) through abandonment and extends to solid waste permitting (ND Department of Health). Non-compliance creates regulatory exposure during ongoing operations.

Construction Commencement Notification mandatory—operator must contact NDIC Field Inspector Jessica Gilkey (701-770-7340) prior to location construction, per APD stipulation

This is a procedural gate condition. While the permit is dated 2025-04-08, the actual commencement of any pad/location construction (as opposed to dirt work authorization) is conditioned on real-time notification to the field inspector. This creates a communication obligation that must be satisfied before earthwork/pad construction begins, ensuring regulatory oversight of physical site development.

🔧 Operator Pattern

Oasis Petroleum (now Chord Energy subsidiary) demonstrates compliance-driven operational planning with pre-drill technical documentation, multi-well pad coordination, and proactive regulatory engagement.
Operator submitted anti-collision analysis (2024-10-30) pre-approval; coordinated Open Hole Log Waiver (approved 2025-05-15) before spud; provided updated facility location notification (2025-03-27) addressing APD stipulation; identified offset operators (self-operated Straw POW 5602 42-17, Ellis 5602 pad, Cyclone 5502 pad) and resolved drill-back notification obligations via waiver (December 2024 letter); implemented closed mud system and remote shutoff requirements per stipulation; maintained detailed directional surveys and geological logging throughout operations (MWD surveys from 2025-05-20 through 2025-07-14 TD). No deviations from permit stipulations or operational non-compliance signals appear in file.

Confidence: High
The permit file is comprehensive and internally consistent. The anchoring permit date (2025-04-08 dirt work authorization) is directly supported by regulatory orders, stipulations, and waivers in contemporaneous and pre-permit documents. The Open Hole Log Waiver (2025-05-15) explicitly conditions alternative logging, approved post-permit but within the operational window before spud (2025-05-20). Anti-collision analysis (2024-10-30) predates approval and is referenced in operator's geometric/safety justification. Subsequent well operations (spud through TD on 2025-07-14) align with the conditional framework. No conflicting dates, missing authorizations, or unexplained deviations detected. Historical obligations (cores/samples, facility location, filter containers, construction notification) are clearly documented with forward operational impact. The file demonstrates a professional regulatory approval workflow with appropriate technical justification and compliance controls.
