Yes
Permit Cycle Assessment
The permit approval (01/24/2025) is explained by contemporaneous regulatory and technical submissions. The approval explicitly conditions the well on: (1) Commission Order 33689 setback specifications tied to specific completion design (wet shoe liner), (2) an approved open hole logging waiver referencing offset well data (05/15/2025), (3) a comprehensive anti-collision analysis showing compliance with industry safety factors and survey frequency requirements, (4) a Surface Use Agreement executed prior to APD submission (01/07/2025) addressing off-spacing drilling authorization under Order 31973, and (5) reliance on a prior facility exemption order (Case No. 28949, Order No. 31500) for non-standard equipment setback. All material permit conditions are tied to documented pre-permit or contemporaneous supporting submissions. No regulatory order or stipulation appears unsupported by technical justification in the file.
Permit Cycle Signals (5)
Commission Order No. 33689 approval granted with explicit 150' setback (north/south) and 500' setback (east/west) within 1920-acre spacing unit, conditioned on production liner cemented in lateral with wet shoe and ability to frac out shoe (2025-01-24)
Non-routine setback geometry tied to specific completion design (wet shoe liner with frac-out capability); directly conditions the permit approval
Open Hole Log Waiver approved under NDIC Rule 43-02-03-31; offset well Straw POW 5602 42-17 (NDIC File No. 28007) within one mile with sufficient open logs to establish formation tops; GR-CBL to run from TD to ground level (2025-05-15)
Permit approval explicitly references the waiver as basis for reduced logging requirement; demonstrates pre-permit coordination with offset well data
Anti-Collision Statement and Anticollision Report submitted showing industry-standard 1.2 separation safety factor, real-time corrected surveys every 93'-100', gamma ray signatures to identify existing wellbore locations, and minimum separation factor analysis across seven offset wells with all separations at 1.297 or greater (2025-01-24)
Multi-well pad geometry requires detailed AC analysis; approval conditional on maintaining specified survey frequency and separation factors; Phoenix 5602 13-17 2B shows Level 3 warning requiring close management
Surface Use Agreement executed with landowner Dustin Mortenson per Order 31973 Drill-Back Policy for off-spacing horizontal wells; Oasis is also operator of adjacent spacing unit, therefore notification waiver requested and implicitly granted (2025-01-07)
Off-spacing drilling from single pad into multiple spacing units permitted via SUA and self-operator waiver; directly addresses regulatory requirement for adjacent operator notification
Facility Setback Exemption Case No. 28949 Order No. 31500 allowing indirect heater placement within 60 feet of wellhead and 21 feet of oil tank, referenced in Facility Statement as basis for non-standard equipment configuration (Unknown)
Facility design modified from standard heated treater to indirect heater with prior regulatory exemption; non-routine configuration that justifies permit approval of related facility layout
Historical Non-Routine Signals (4)
Six-well pad configuration (Ellis 5602 13-17 2B, 3B, 4B and Phoenix 5602 13-17 2B, 3B, 4B) with consolidated production flowline routed 1,756 feet outside pad limits to remote Archerfield CTB facility under NDAC 43-02-03-48.1 consolidation request (2025-03-27)
Multi-well pad and remote facility consolidation creates ongoing operational and environmental compliance obligation; flowline route outside pad limits requires sustained monitoring and maintenance to prevent cross-property impacts
Geologic Report and cuttings/core sample submission requirements per North Dakota Century Code Section 38-08-04 and NDAC 43-02-03-38.1; samples to be collected at 30' intervals (vertical/build) and 200' intervals (lateral), shipped within 30 days of completion, cores within 180 days (2025-01-27)
Mandatory submission deadline and sample handling procedures persist through completion phase and post-drilling period; non-compliance subject to civil penalty up to $12,500 per day violation; affects well operations schedule and closure documentation
Fresh water impoundment (40K bbl, 150' diameter AST/Poseidon tank) temporary facility construction scheduled December 3, 2025 through January 25, 2025 to supply frac fluids for Ellis and Phoenix pad wells; facility siting at specific coordinates (48.34244 N, 103.84168 W) (2025-12-09)
Temporary facility approval ties well completion timing to frac supply infrastructure; spud date (05/23/2025) suggests completion operations planned for late 2025; water containment and disposal obligations persist while tank is on location
H2S monitoring requirement; geologist noted H2S may be present in Mission Canyon Formation; wellsite H2S Monitoring supervisor (Nate Linde) assigned; gas detection via Pason Systems with C1-C4 chromatography and CO2 detection throughout drilling (2025-05-23)
H2S hazard designation persists for all future well operations, workovers, and abandonment; requires continued presence of qualified H2S monitor during any open-hole operations and establishes safety protocol requirements beyond this drilling phase

Confidence Assessment
Level: High Rationale: Well file contains complete permit sequence with exact approval date (01/24/2025), unambiguous permit conditions tied to specific regulatory orders (No. 33689) and technical submissions (open hole waiver 05/15/2025, anticollision report 10/30/2024, SUA 01/07/2025). All major permit stipulations reference contemporaneous supporting documents in the file. Geological drilling operations completed (spud 05/23/2025, TD reached 06/19/2025) provide post-permit operational confirmation. No material gaps between permit issuance and documented regulatory/technical justifications.
