📋 Permit Cycle Assessment

The freshwater tank placement approval (12-09-2025, Form ID 285444) is supported by an operator notification of intent to place a temporary 40K-barrel AST on an adjacent pad to supply multiple wells including Roen 5202 41-24 2B. The notification was received 12-01-2025 and approved 12-09-2025 by the Reclamation Supervisor with no stated objections or contingencies. However, the file lacks a contemporaneous explanation for why this specific approval was issued on that date—no prior denial, no amended submission, no regulatory trigger letter, and no condition imposed beyond the implicit requirement to follow standard North Dakota infrastructure and waste management rules (filter sock containers, leak-proof design, covered construction, plug-back of unused containers after rig demobilization, as referenced in the August 2023 DMR circular and applicable ND Admin Code). The approval is routine and administrative rather than exceptional, and it enables the pad-level completion campaign for which the well was drilled. The permit-cycle analysis identifies supporting infrastructure approval but does not establish that a specific regulatory or operational contingency required the approval on 12-09-2025 versus an earlier date.

🔍 Permit Cycle Signals (5)

Open Hole Log Waiver (NDIC Rule 43-02-03-31) granted based on proximate offset well (Novak 1-25) with open logs; GR-CBL run from TD to ground level required

Direct

📄 Form 4 Sundry Notice (Form ID 212275), Reviewer: Ross Edison, Geologist
📅 10-15-2024 (Exact confidence)

Nonstandard waiver of open hole log requirement, conditioned on offset well data and CBL substitute. Directly justifies drilling operations without full logging suite.

Core and Sample Submission Order (ND Century Code § 38-08-04, ND Admin Code § 43-02-03-38.1): Samples required at 30' intervals (vertical/build) and 200' intervals (lateral); submission to ND Core Library within 30 days of completion

📄 MWD Survey Certification signed by Eric Miller, Total Directional Services; Directional Survey Report header
📅 01-03-2025 (Exact confidence)

Demonstrates execution and independent verification of well geometry. Survey conducted and certified during the drilling window. No deviations from planned azimuth noted; supports permit compliance on well path.

No contemporaneous explanation found for the specific permit approval anchored to 12-09-2025 (Freshwater Tank approval effective date). The permit application and supporting technical documents (waiver request, sample orders, survey certifications) predate the approval by 2–6 months; no amendment, update, or condition letter issued at or near the effective date.

Unclear

📄 File bundle: Waiver dated 10-14-2024; Spud Notification dated 12-31-2024; MWD survey dated 01-03-2025; Freshwater Tank Form approval dated 12-09-2025 (effective)
📅 Unknown (Missing confidence)

The specific permit action (freshwater tank authorization) occurs in isolation with no documented reason for timing, denial of prior submission, or regulatory trigger identified in the file. The tank notification itself (12-01-2025 received) precedes approval by 8 days, but no contingency closure or permit-conditional language is evident.

📖 Historical Context (4)

Offset Well Data Reliance (Novak 1-25, NDIC File No. 8240): Operator substituted open hole logging via waiver by citing formation-top equivalence from offset well within 1-mile radius. Waiver effective 10-15-2024.
📄 Form 4 Sundry Notice (Form ID 212275), Section: 'offsetting well Novak 1-25' · 📅 Unknown
GR-CBL logging from TD to ground level is required as a condition of the waiver. If CBL data is missing or non-conforming at final well report, the operator faces potential enforcement and may be required to conduct open hole logs retroactively. This constraint persists through well completion and abandonment documentation.

Core and Sample Submission Mandate (ND Century Code § 38-08-04): Operator required to submit all drill cuttings (90' intervals through vertical/build; 200' through lateral) and any core to ND Geological Survey Core Library within 30 days of completion. Civil penalty provision: up to $12,500 per day violation.
📄 Letter from Ross Edison, Geologist, ND DMR Oil & Gas Division, dated 10-14-2024 · 📅 Unknown
Compliance deadline is 30 days post-completion. Failure to submit samples/cores triggers ongoing daily penalties. This statutory obligation is independent of well permit and remains enforceable at any future inspection or audit. Operator must maintain chain-of-custody documentation and post-completion logistics.

Drill-Back Notification and Offset Coordination: Affidavit dated 01-24-2024 confirms Oasis notified Kraken Operating LLC (adjacent unit operator) of plan to drill back into adjacent unit. Notification sent to Justin Mayhall at Kraken (jmayhall@krakenoil.com, 713-360-7705).
📄 Affidavit Affirming Drill Back Notification, well names: Roen 5202 41-24 2B, Roen 5202 41-24 3B, Hoehn 5202 41-24 2B/3B/4B/5B; Permit No. 164918, 165330, 165332, 165334, 165336, 165337 · 📅 Unknown
Confirms inter-operator coordination for directional drilling risk. Creates documentary evidence of neighborly notification (ND practice, often required in spacing unit disputes). If drill-back drilling intersects Kraken wellbores or causes subsurface interference, Oasis has defense record of notice. Conversely, Kraken retains right to challenge wellbore migration post-drilling if actual intersection occurs outside agreement terms.

Surface Use Agreement Affidavit (01-24-2024): Oasis obtained executed Surface Use Agreement for Roen 5202 41-24 2B and 3B (locations SWSW & SESW, Section 24-152N-102W) not located on spacing unit. Legal description and proof of agreement on file.
📄 Affidavit Affirming Surface Use Agreement, Permit No. 164918, 165330 · 📅 Unknown
Well locations off-spacing unit require landowner consent. Agreement is binding documentation of mineral rights holder approval. If dispute arises over surface access, royalty interest, or plugging/abandonment liability, this affidavit and underlying SUA are primary evidence of operator authority. Constraint persists through well life into reclamation phase.

🔧 Operator Pattern

Oasis Petroleum North America LLC operates a coordinated multi-well pad (Roen 5202 41-24 series and Hoehn 5202 41-24 series) in McKenzie County targeting Middle Bakken formation via horizontal drilling. Operator demonstrates competence in directional execution (MWD-guided, landed in target window 12.5' into Middle Bakken), offset well coordination, and regulatory compliance documentation (waivers, affidavits, drill-back notifications). Operator has secured surface use agreements for off-unit locations, contracted third-party drilling and directional services (Patterson 808 rig, Total Directional Services), and arranged mud supply (Mountain Mud & Supply). Geologic support provided by Core Geologic LLC. Operator leverages nearby offset well data to justify logging waivers (routine practice in Bakken field).
Spud date 12-25-2024, TD reached 01-03-2025 (9 days drilling); Affidavits and notifications dated 01-24-2024 predate well spud by ~11 months, showing advance planning; MWD survey and wellsite geology integration (multicrew mud logging, gas detection, rock sampling at programmed intervals) reflect standard Bakken execution; Freshwater tank supply logistics coordinated across pad for completion phase (approvals received in early December 2025 for January tank deployment).

Confidence: High
Well file contains complete drilling operations timeline, directional survey with independent certification, regulatory letters and waiver approvals with specific citations to ND statutory code, operator affidavits with notarized signatures, geologic logs (mud, cuttings, formation tops), and permit applications with approved/received status marks and reviewer names/dates. No OCR artifacts render critical dates or regulatory references ambiguous. Permit effective dates, application submission dates, and operational milestones are clearly marked. The primary gap is explanatory—the file does not articulate the specific regulatory or operational reason for the freshwater tank approval on 12-09-2025, but this is an administrative approval for temporary infrastructure, not an exceptional permit condition. Historical context (offset reliance, sample submission, drill-back coordination, surface agreements) is documented with high precision and citation rigor.
