📋 Permit Cycle Assessment

The well file contains material contemporaneous documentation supporting the permit approval for the Roen 5202 41-24 3B. Key justify signals are: (1) Open Hole Log Waiver (10/15/2024), directly conditioning drilling without full log suite based on offset well proximity—a direct regulatory waiver reducing operational burden and enabling the drilling program. (2) State Geologist's Core & Sample Preservation Order (10/14/2024), mandating sample collection intervals and shipment timelines—a structural constraint on all operations from spud forward. (3) Fresh Water Supply Sundry approval (12/09/2025), authorizing temporary surface facility for hydraulic supply to the pad. (4) Spud notification (01/07/2025), documenting formal commencement. However, the well file does NOT explicitly contain the original APD (Application for Permit to Drill) approval letter with a dated permit issuance or formal permit number tied to a specific regulator approval action post-waiver. The existing sundries document post-spud activity (1/5/2025 spud, 1/7/2025 notification, 12/9/2025 water tank approval). If a formal APD permit approval document exists, it is not included in this file extract. The waiver and core order demonstrate regulatory engagement pre-drilling, but the primary permit issuance approval itself is not explicitly present.

Open Hole Log Waiver (NDIC Rule 43-02-03-31) – Approved via Well File #9681

Direct

📄 Sundry Form 212278 (Form ID: 212278), dated 10/14/2024, approved 10/15/2024
📅 2024-10-15 (Exact confidence)

Operator requested and received waiver to forego open hole logging due to proximity (within 1 mile) of offset well NOVAK 1-25 (NDIC File No. 8240) with sufficient logs. Only GR-CBL run required TD to ground level. This waiver directly enables the well design and drilling program without conventional full openhole suite.

Core and Sample Preservation Order – Effective date 10/14/2024 (State Geologist directive)

Supporting

📄 Letter from Ross Edison (Geologist, NDIC) dated 10/14/2024, referencing ND Century Code §38-08-04 and ND Admin Code §43-02-03-38.1
📅 2024-10-14 (Exact confidence)

Mandatory requirement conditioning drilling operations: operator must collect samples at specified intervals (30' vertical/build, 200' lateral), ship within 30 days of completion, and preserve cores within 180 days. Failure to comply triggers civil penalties up to $12,500 per day violation. This is a standing regulatory obligation tied to the drilling permit.

Fresh Water Supply Sundry (Form 285445) – Approved 12/09/2025, effective for tank build starting 12/13/2025

Supporting

📄 Well Sundry Form, File 41229, Form ID 285445, Approved by Cody VanderBusch (Reclamation Supervisor) on 12/09/2025
📅 2025-12-09 (Exact confidence)

40,000 bbls temporary AST/Poseidon freshwater tank approved to feed multiple well pads (including 41-24 3B) for frac and coil operations. Tank location and specifications explicitly approved. This is a pre-completion operational ancillary approval contemporaneous with drilling readiness.

Spud notification filed (Form 224791, File 41229) – Received 01/06/2025, effective 01/07/2025

Supporting

📄 Well Sundry Form 224791 ('Notification of Work Performed'), spud via Patterson 808 rig
📅 2025-01-07 (Exact confidence)

Documents well spud on 01/05/2025; receipt and approval mark commencement of drilling operations and trigger regulatory timeclocks for geological logging and compliance reporting.

📖 Historical Context (4)

Offset well data and geologic prognosis – NOVAK 1-25 (NDIC File 8240) within 1-mile radius
📄 Open Hole Log Waiver request (Form 212278) and Core Geologic wellsite geologist report · 📅 Relative (pre-spud, supporting waiver dated 10/14/2024)
Offset well data was the basis for waiving conventional openhole logging and establishing the landing target (10,825' TVD at Lodgepole top, subsequently adjusted to 10,822.97' TVD at Middle Bakken). This relationship conditions all future drilling decisions, completion design, and interference monitoring for the life of the well and any future offsetting activity by operator or third parties.

Drill-back and Surface Use Agreements – Multiple adjacent wells (Hoehn pads, Roen 5202 pads) with affidavits filed 01/24/2024 and 01/24/2024
📄 Affidavits of Drill Back Notification and Surface Use Agreement (filed January 2024); notification to Kraken Operating LLC (adjacent operator of Hoehn units) · 📅 2024-01-24
Well is part of a multi-well pad (Roen 5202 41-24 2B, 3B; Hoehn 5202 41-24 2B, 3B, 4B, 5B—six wells total). Drill-back and surface use agreements with adjacent mineral owner/operator (Kraken Operating LLC) establish long-term operational constraints: commingling rights, spacing unit definitions, and adjacency obligations. These persist through well life and any future penalty assessments.

Filter Sock and Waste Management Directive – State geologist letter dated 08/28/2023 (NDIC Oil and Gas Division)
📄 Letter from NDIC titled 'Filter Socks and Other Filter Media – Leakproof Container Required,' effective 06/01/2014 forward · 📅 2023-08-28 (issuance); 2014-06-01 (effective)
Standing operational requirement: operator must maintain on-site leakproof, covered, placard containers for filter disposal beginning at well spud and continuing through cleanup, completion, and flowback. Non-compliance invokes ND Admin Code §43-02-03-19.2 waste disposal violations. This obligation extends through the entire well lifecycle and all drilling/completion operations.

Casing and completion program design – Surface 9 5/8" J-55, Intermediate 7" P-110, lateral 6" drill to TD
📄 Core Geologic wellsite geological report (dated February 2025), Well Summary section · 📅 2025-01-05 to 2025-02-18 (drilling dates reflected in report)
The casing design and hole trajectory (landing in Middle Bakken at 10,822.97' TVD, 100% exposure to target) establish the well geometry constraint for all future completion, stimulation, and production decisions. The formation dip (89.75° average) and facies targeting (C to D facies, 10-foot window) condition pressure management and fluid flow dynamics.

🔧 Operator Pattern

Oasis Petroleum North America LLC demonstrates standardized multi-well pad development with inter-operator coordination (Hoehn/Roen spacing unit, Kraken adjacency agreements). Geologic program includes onsite and remote geosteering (Core Geologic, LLC), MWD services (Total), and electronic drilling records (Pason Systems). Operator has executed formal surface use agreements and drill-back notifications, indicating operational maturity and regulatory compliance culture.
Multi-well pad approval (6 wells in single spacing unit); formal affidavits for drill-back and surface use; standardized rig (Patterson 808) and service company selection; onsite/remote geological staffing; documented sample and core collection protocol compliance.

Confidence: Medium
The file contains robust operational and geological documentation (wellsite geologist reports, sundry forms, waiver approvals, affidavits) that explain the drilling program and regulatory framework. However, the primary APD permit issuance document itself (formal permit number, issuance date, Director approval signature) is NOT present in the extract. The waiver (10/15/2024) and spud notification (01/07/2025) are clear, but the anchor permit approval date is not explicitly stated in the supplied documents. If permit approval occurred between 10/15/2024 (waiver approval) and 01/05/2025 (spud), supporting signals exist; if approval was prior to 10/15/2024 or after 01/05/2025, the contemporaneous nexus is weakened. Recommend verification of the formal APD approval date and number from the NDIC permit database to complete the permit-cycle intelligence.
