📋 Permit Cycle Assessment
The well file contains limited direct contemporaneous explanation for the October 31, 2025 permit approval. The file shows operator transfer approval (Form 15) issued on the same date, with new bonding (CMS0358791) established by Devon Energy. However, no Application for Permit to Drill approval letter, permit issuance order, or NDIC authorization document dated October 31, 2025 appears in the file. The well had already spudded May 25, 2025 (under prior operator Grayson Mill) and reached TD by June 20, 2025. The October 31 action is primarily an operator-of-record transfer, not a new drilling permit approval. The pre-drilling waivers (suspension of drilling, filter sock waiver, tubing/packer variance, open hole log waiver) approved April–May 2024 and the April 23, 2025 permit renewal explain regulatory clearance for the initial drilling phase completed under the predecessor operator. The transfer approval itself is conditioned on the RLI bond posting and represents assumption of operational responsibility by the new entity.
🔍 Permit Cycle Signals (4)
📄 Form 15 Notice of Transfer dated October 31, 2025; Bond approval CMS0358791
📅 2025-10-31 (Exact confidence)
Contemporaneous to permit approval date. Transfer establishes new operator responsibility and bonding continuity under new entity, directly conditioning continued well operations.
📄 Form 15 and Power of Attorney documentation; bond amount $100,000
📅 2025-10-31 (Exact confidence)
Bond is a direct regulatory requirement tied to operator transfer. Establishes financial assurance mechanism required for permit continuation under new operator.
📄 MWD Survey Certification and Directional Survey Report; Survey Company Total Directional Services; measured depth 22,492 feet, TVD 11,079.71 feet
📅 2025-06-20 (Exact confidence)
Well achieved total depth with measured survey data confirming conformance to approved drilling plan and spatial corridor requirements (180° azimuth, within 500' north-south axis corridor per NDIC Order No. 33440).
📄 Sundry Form 251214 (Notification of Work Performed - Casing/Cement); Magnum Cementing Services report; 39 sacks MAG G 15.8 cement, 4.63 bbls placed at 20' MD
📅 2025-05-30 (Exact confidence)
Completion of surface casing confirms structural integrity requirement satisfied prior to drilling phase conclusion. Documented cement work validates pressure containment capability.
📖 Historical Context (8)
Suspension of Drilling (SOD) waiver approved May 21, 2024 for 90 days under NDAC 43-02-03-55
📄 Sundry Form 183239; Reviewer Dan Kuchar approval · 📅 2024-05-21
Establishes precedent for phased drilling strategy using small rig for surface hole followed by larger rotary rig within 90-day window. Constraint persists as regulatory acknowledgment that well pad operations may occur in phases; impacts future plug-and-abandon timelines if drilling does not proceed.
Tubing/Packer variance approved May 2, 2024 allowing casing without conventional tubing string
📄 Sundry Form 183226; Reviewer Stephen Fried approval; justification includes #29 and 32# surface casing, API burst 11,220 psi, safety factor 0.85 · 📅 2024-05-02
Non-standard completion design remains in effect for flowback and production phases. Specifies pressure monitoring (300# gauge) and high-level safety thresholds (227-230 psi estimate); constrains production equipment pressure ratings and shutdown protocols.
Open Hole Log waiver approved April 30, 2024 via reference well Olga 150-99-15-22-1H (NDIC #20737)
📄 Sundry Form 183205; Reviewer Ross Edison approval; waiver allows GR-CBL log only · 📅 2024-04-30
Establishes reduced logging obligation based on offset well proximity (<1 mile). Impacts formation identification certainty for regulatory compliance and future zone interpretation; GR-CBL limited to cement evaluation and top determination.
Filter Sock Container waiver approved May 3, 2024 for drilling phase only
📄 Sundry Form 183212; Reviewer Dan Kuchar approval; operator does not use filter media during drilling · 📅 2024-05-03
Waiver scope limited to drilling phase only. Implies completion and flowback phases require filter sock container compliance per NDAC 43-02-03-19.2; operator must implement containment for completion-phase waste streams.
Bakken Setback compliance condition requiring south setback based on production liner with wet shoe and frac-out capability
📄 APD Application for Permit for New Well - Horizontal; Bakken Setback Summary Statement (undated stipulation in permit) · 📅 Unknown
Operational constraint persists throughout well life. Well bore must remain within 150° setback from north and south boundaries of 2560-acre spacing unit (Sections 15, 16, 21, 22 T150N-R99W). Wet shoe design with frac-out capability conditions any future re-completion or side-track decisions.
Pool definition: South Tobacco Garden-Bakken from 50 ft above Bakken top to 50 ft below Three Forks top
📄 APD Application for Permit for New Well - Horizontal; NDIC Field Order Info per Commission Order No. 33440 · 📅 Unknown
Defines producible interval for regulatory reporting, royalty calculation, and allocation of production to spacing unit. Bounds future recompletion rights and commingling restrictions.
H2S Mitigation Plan prepared March 11, 2024 (Rev. 0) identifying 100 ppm ROE 3000 ft, 500 ppm ROE 1373 ft
📄 Hydrogen Sulfide Mitigation Plan; Emergency Response Plan dated March 2024 · 📅 2024-03-11
H2S exposure protocol remains active during drilling, completion, and production. Requires continuous windsocks, trained personnel, SCADA monitoring, high-level alarms (75%/90% tank capacity set points), and emergency response coordination with Sakakawea Area Spill Response (SASR).
Cores and Samples requirement: samples from Base of Last Charles Salt at 30' intervals (vertical/build), 200' intervals (lateral); cores to ND Geological Survey within 180 days
📄 Letter from Richard A. Suggs, ND Geological Survey, dated April 29, 2024 · 📅 2024-04-29
Ongoing compliance obligation. Operator must ship samples within 30 days and cores within 180 days of drilling completion to ND core library. Non-compliance triggers up to $12,500 civil penalty per day (NDCC 38-08-16).
🔧 Operator Pattern
Grayson Mill Operating, LLC initially drilled and conducted initial operations. Well transferred to Devon Energy Williston, LLC October 31, 2025. Both operators headquartered at 333 West Sheridan Avenue, Oklahoma City, OK 73102 (shared address suggests corporate relationship or asset management structure). Grayson Mill proactively sought regulatory waivers and demonstrated operational maturity via H2S planning, emergency response protocols, and coordination with Watford City municipal planning.
Suspension of drilling waiver (May 2024), multiple technical variances (tubing/packer, open hole log, filter sock), and substantive H2S/Emergency Response Plans submitted March 2024. Transfer paperwork shows Lindsey N. Miles, Vice President, signed for both entities. Devon Energy bond ($100,000 via RLI Insurance) posted immediately upon transfer approval, indicating continuity of operations and regulatory standing.
Confidence: Medium
File contains comprehensive technical documentation (APD, waivers, directional surveys, cementing records, H2S/ERP plans, location plats, well design details) supporting the well's drilling and initial completion phases. However, the October 31, 2025 permit approval date (the stated anchor) is not directly explained by a permit issuance letter or new APD approval document in the file. Only the contemporaneous operator transfer (Form 15) and bond posting are present. This suggests the October 31 action is primarily administrative (transfer/bonding) rather than a new drilling permit decision. Earlier approvals (April–May 2024 waivers, April 23, 2025 renewal) explain regulatory clearance for the drilling phase that occurred May–June 2025. The gap between documented drilling completion (June 20, 2025) and the October 31, 2025 permit action suggests a possible production facility or completion phase development not fully documented in this file subset. Confidence is medium because core drilling/completion permits are well-documented, but the specific October 31 action and any associated production or re-completion authorization are not explicitly present.
