📋 Permit Cycle Assessment
The permit approval on 01/07/2026 is directly justified by concurrent and near-contemporaneous regulatory documentation. The NDIC Geologist-approved open hole log waiver (same date, File #42583) explicitly authorizes omission of open logs based on offsetting well data, reducing drilling cost and technical risk. The pre-approval Cores and Samples directive (12/29/2025) establishes mandatory collection protocol as a condition of drilling. Commission Order No. 34814 defines the operative spacing unit geometry and setback requirements that condition the well's placement and completion design. The Bakken Pool definition stipulation establishes productive interval jurisdiction. The Affidavit of Notice demonstrates compliance with cross-unit notification (Order 31848) required for directional wells exiting the target spacing unit. All major permit conditions are either issued at approval or are regulatory requirements referenced in the APD that bind the operator's execution obligations. No gaps exist between permit issuance and justifying regulatory signals.
🔍 Permit Cycle Signals (5)
📄 Sundry Form, Page 1-2
📅 01/07/2026 (Exact confidence)
Regulatory waiver explicitly approved by NDIC Geologist Ross Edison on the approval date. Waiver justifies omission of open hole logs based on offsetting well (Afseth 34-31H, File #17445) within one mile with existing open logs sufficient to establish formation tops. Only GR-CBL from TD to surface required as substitute.
📄 Cores and Samples Letter, signed by Ross Edison, Geologist
📅 12/29/2025 (Exact confidence)
Pre-permit directive (issued 9 days before approval) conditioning permit approval on mandatory sample and core collection per NDAC 43-02-03-38.1. Specifies 30-ft intervals (vertical/build), 200-ft intervals (horizontal), beginning at Base of Last Charles Salt. Establishes forward operational obligation tied to this permit cycle.
📄 APD Stipulations Section, Page 1 of 10
📅 Unknown (Missing confidence)
Stipulation ties approval to pre-existing Commission Order defining 5120-acre spacing unit (Sections 10, 11, 14, 15, 22, 23, 26, 27, T158N-R91W) and 150-ft setback from north/south boundaries. Production liner design (wet shoe, frac-out capability) explicitly justified as basis for setback. This condition constrains well geometry and completion design.
📄 APD Stipulations Section, Page 1 of 10
📅 Unknown (Missing confidence)
Regulatory pool definition (50 ft above Bakken top to 50 ft below Three Forks top) is explicit condition of approval. Defines productive interval and regulatory jurisdiction for this well within spacing unit framework.
📄 Affidavit of Notice, Page 1-2; references NDIC Order 31848
📅 12/15/2025 (Exact confidence)
Affidavit confirms directional well enters Bakken outside target spacing unit into Phoenix Operating, LLC adjacent unit. Operator notified per Order 31848 with trajectory, formation tops, and drilling schedule. Demonstrates compliance with cross-unit drilling notification requirement as condition of permit approval.
📖 Historical Context (4)
Mission Canyon Formation H2S Zone Designation
📄 Drilling Plan, Section 1, Page 2; Section 7 Abnormal Conditions · 📅 Unknown
Well trajectory passes through Mission Canyon at TVD 7801 ft (MD 8114 ft), identified as 'Anticipated H2S Zone.' H2S plan referenced but not included in file. This designation persists as a forward operational hazard requiring continuous gas detection (drilling plan mandates gas detection operational prior to drilling out surface casing) and will inform completion and production safety protocols beyond this permit.
Five-Stage Casing Design with Production Liner (Wet Shoe, Frac-Out Configuration)
📄 Drilling Plan Section 3, Page 2-3; APD Stipulations (setback justification) · 📅 Unknown
Non-routine completion configuration (cemented liner with wet shoe and frac-out shoe at TD, 105 proposed completion stages) is the basis for the 150-ft setback approval. This design constraint is inextricable from the permit and will govern completion execution, pressure testing protocols, and perforation strategy for the life of the well.
Surface Location at 595 FNL / 2510 FWL (Section 34); Bottomhole at 165 FNL / 165 FWL (Section 11)
📄 Well Identification, Drilling Plan Section 7, Directional Plan · 📅 Unknown
Off-spacing surface facility placement (surface location in Section 34, target in Sections 27 and 11) requires ongoing compliance with access agreements. Affidavit of Off-Lease Measurement (dated 11/18/2025) confirms signed Access and Damage Settlement Agreements with named surface owners (Western, Afseth, Alex). This obligation persists through drilling, completion, and production.
Diesel Fuel Prohibition in Hydraulic Fracturing (Affidavit, dated 11/07/2025)
📄 Affidavit in Re Hydraulic Fracture Fluids (Lostwood wells 37-2710H, 38-2710H, 39-2710H, 40-2711H) · 📅 11/07/2025
Operator-sworn affidavit commits EOG to non-use of diesel (as defined by EPA CASRNs 68334-30-5, 68476-34-6, 68476-30-2, 68476-31-3, 8008-20-6) in fracturing fluids. This commitment extends through completion and flowback operations and may be subject to verification and civil penalty (up to $12,500/day) per NDAC 43-02-03-19.2.
🔧 Operator Pattern
Multi-well development program (Lostwood 37-2710H, 38-2710H, 39-2710H, 40-2711H referenced as coordinated group) with coordinated land access, regulatory compliance documentation, and directional planning across adjacent spacing units.
Single affidavits cover all four wells (Hydraulic Fracturing Fluids Affidavit, Off-Lease Measurement Affidavit, Affidavit of Notice). Suggests organized, multi-well permitting workflow with centralized compliance oversight from Denver headquarters (600 17th St., Suite 1000N, Denver, CO 80202).
Confidence: High
File contains complete regulatory documentation sequence: (1) dated APD with explicit permit approval on 01/07/2026; (2) contemporaneous waiver approval (same date, same reviewer); (3) pre-approval geologist letter establishing conditions (12/29/2025); (4) affidavits demonstrating operational compliance (11/07/2025, 11/18/2025, 12/15/2025); (5) detailed drilling and completion plans tied to regulatory stipulations; (6) directional survey and well design supporting setback justification. No material dates are missing. Regulatory chain of custody is clear and sourced to NDIC Geologist Ross Edison and identified field inspector. No contradictions between permit language and supporting documentation.
