Permit Explained: 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 (Exact confidence)

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

📄 Sundry Form FORM ID 247807, received 05/15/2025, approved 05/15/2025
📅 2025-05-15 (Exact confidence)

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 (Inferred confidence)

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

Supporting

📄 Affidavit dated 01/07/2025, notarized by Margaret Parisien; APD Operator Assertions section
📅 2025-01-07 (Exact confidence)

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

📄 APD FACILITY STATEMENT section and facility construction diagram
📅 Unknown (Missing confidence)

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 Context (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
📄 Sundry Form FORM ID 238835 dated 03/27/2025 (pre-permit notification); Production Layout and Flowline Route drawings dated 2024 · 📅 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
📄 Letter dated 01/27/2025 from ND Geological Survey signed by Ross Edison, Geologist · 📅 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)
📄 Sundry Form FORM ID 285451 received 12/01/2025, approved 12/09/2025 · 📅 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
📄 Geologic Report Well Summary and APD Abnormal Conditions section · 📅 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

🔧 Operator Pattern

Oasis Petroleum (Chord Energy subsidiary) demonstrates integrated multi-well pad development strategy with consolidated production infrastructure, off-spacing drilling via operator-controlled adjacent units, and reliance on prior-issued regulatory exemptions (facility setback Order 31500) to streamline permitting of non-standard configurations
Operator controls both target spacing unit (NWNE 17-156N-102W) and adjacent unit into which wellbores traverse; executed SUA with single landowner for six-well pad; requested self-operator notification waiver under Order 31973; production routed 1.7 km to centralized Archerfield CTB facility consolidating output from seven wells across multiple fields; facility design incorporates prior exemption order to reduce equipment setbacks

Confidence: High
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.
