Target Formation: Middle Bakken
Permit Explained: Partially

📋 Permit Cycle Assessment

The October 2025 transfer approval is explained by the Form 15 operator change documentation (Grayson Mill to Devon Energy) and new bonding (CMS0358791). However, the well file contains no contemporaneous documentation dated to or near October 2025 that explains the trigger or conditions specific to that transfer approval beyond the standard bonding and operator responsibility assumption. The original APD permit (December 2011) and subsequent drilling authorizations (2012 drilling suspension and CBL waiver) are structural and historical, not contemporaneous with the October 2025 transfer approval. The August 2025 freshwater tank sundry notice is the closest contemporaneous support document but addresses only completion-phase infrastructure, not the operator transfer itself. No correspondence or regulatory order dated October 2025 is present in the file to explain why the transfer was approved at that specific time or under what conditions.

Contemporaneous permitting for support infrastructure tied to well completion phase; demonstrates active operational authorization for this specific well

Cement Bond Log requirement and waiver request for open-hole logs (NDAC 43-02-03-34) with condition that CBL be run on production casing; nearby offset well data referenced

Direct

📄 Form 4 (Sundry Notice), dated May 10, 2012; NDIC approval communication dated same
📅 2012-05-10 (Exact confidence)

Regulatory waiver conditioning drilling operation; directly tied to well design and compliance with cementation rules; offset data (Twobins well) used to justify deviation

Drilling suspension approval under NDAC 43-02-03-55 for up to 90 days; two-rig program (small rig for surface casing, larger rig for TD) to optimize cost/schedule

Direct

📄 Form 4 (Sundry Notice), dated January 26, 2012; signature date 1/27/2012
📅 2012-01-27 (Exact confidence)

Non-standard drilling execution plan explicitly approved by regulator; directly conditions permit approval and operational sequence; time-bound by 90-day suspension window

Original APD permit approval (Permit 22056) issued December 13, 2011, with permit stipulations requiring closed mud system on multi-well pad, NDIC inspector contact, and back-to-back drilling of Wagenman 29-32 #1H and #2H to justify spacing unit

Direct

📄 Engineering Technician approval letter (David Tabor) dated December 13, 2011 and completed Application for Permit to Drill Horizontal Well (Form H)
📅 2011-12-13 (Exact confidence)

Original permit foundation; establishes hard-line compliance requirements (spacing unit justification via back-to-back drilling, mud system closure, inspector pre-location contact); forms basis for all subsequent operations

📖 Historical Context (5)

Back-to-back drilling requirement for Wagenman 29-32 #1H and #2H to justify 1,280-acre spacing unit (Sections 29 & 32-T155N-R101W) as permit stipulation
📄 December 13, 2011 Engineering Technician approval letter; noted as PERMIT STIPULATIONS · 📅 2011-12-13
Spacing unit justification is a structural obligation that persists through well life; any deviation from back-to-back drilling sequence or well abandonment out-of-sequence could trigger re-examination of spacing unit validity and require regulator notification

Closed mud system requirement on multi-well pad with contingent cuttings disposal (site-specific approval required); enforcement contingent on NDIC Field Inspector determination
📄 December 13, 2011 approval letter, PERMIT STIPULATIONS section · 📅 2011-12-13
Ongoing environmental and operational compliance mandate; drilling and completion operations remain conditioned on closure system maintenance and site-specific inspector approval; violation could trigger enforcement action

Cement bond log requirement with minimum compressive strength specification (500 psi within 12 hours for tail cement, 500 psi before plug/test for production casing)
📄 December 13, 2011 approval letter, 'Surface casing cement' and 'Logs' sections · 📅 2011-12-13
Cementing specification is a forward obligation tied to well integrity and casing isolation; persists through completion and into abandonment planning; non-compliance creates liability under NDCC 38-08 Chapter compliance requirements referenced in all operator bonds

Confidential status granted for six months from spud date (March/April 2012) for all operational and technical information except production runs
📄 December 13, 2011 approval letter, 'Confidential status' section · 📅 2011-12-13
Confidentiality obligation persists through operator transfer; Devon Energy Williston assumes confidentiality compliance responsibility; any breach or unauthorized disclosure remains subject to NDIC enforcement authority and may affect future permit approvals

Stripper well property designation effective June 25, 2020 based on production performance during qualifying period (September 1, 2018 – August 31, 2019); average daily production 29.6 BOPD; only applicable to Bakken Pool per determination letter
📄 June 25, 2020 Stripper Well Determination letter from NDIC Petroleum Engineer David McCusker · 📅 2020-06-25
Stripper well designation affects future tax treatment and regulatory flexibility; designation is pool-specific (Bakken only) and subject to ongoing production monitoring; could trigger status change if production exceeds thresholds, affecting regulatory treatment and compliance requirements

🔧 Operator Pattern

Multiple operator transitions with consistent asset acquisition and bond consolidation; operational continuity maintained through formal transfer process
Ownership chain visible: Brigham Oil & Gas LP (original APD applicant, December 2011) → Statoil Oil & Gas LP (via principal name change September 26, 2018) → Equinor Energy LP (via principal name change September 26, 2018) → Grayson Mill Operating, LLC (via Form 15 transfer April 26, 2021) → Devon Energy Williston, LLC (via Form 15 transfer October 31, 2025, approved). Single surety (RLI Insurance Company) appears throughout with bond number changes at each transition. No evidence of operational non-compliance or enforcement actions in file; transfers executed through standard regulatory procedure with bonding continuity maintained.

Confidence: Medium
File contains clear structural permitting documentation from original APD approval (2011) through drilling authorizations (2012) and stripper well determination (2020). The October 31, 2025 operator transfer approval is documented via Form 15 and cover letter, confirming the approval event. However, no contemporaneous documentation (dated to or near October 2025) is present that explains the *reason* for or *conditions of* the October 2025 transfer approval specifically. The transfer appears to be a routine operator change with bonding transition rather than a response to well-specific technical issues, compliance failures, or regulatory orders. Confidence is reduced due to absence of contemporaneous permit-cycle explanation documents specific to the October 2025 approval date, but structural and historical context is high-confidence.
