📋 Permit Cycle Assessment

The permit approval on 2026-01-15 is explained and conditioned by Commission Order No. 34129 (1280-acre spacing unit with 150'/500' setback regime), the wet shoe completion design justified by directional survey and cementing controls, anticollision analysis dated 2025-09-23 confirming safe separation from offset wells with Level 3 risk mitigation, pre-existing NDIC facility exemption (Case 28949, Order 31500) for indirect heater placement, and Federal minerals notification requiring BLM coordination. All material permit conditions are documented with explicit regulatory bases or operator-submitted technical justifications. Operator waived notification requirement for off-spacing lateral penetration under Order No. 31848 because Oasis operates adjacent spacing unit.

🔍 Permit Cycle Signals (5)

Commission Order No. 34129 establishes 1280-acre spacing unit (Sections 28 & 29-148N-92W) and conditions approval on specific setback requirements: 150' from east boundary at heel and toe, 500' from north, south, and west boundaries. Setback justified by production liner with wet shoe and ability to frac out shoe.

📅 2026-01-15 (Exact confidence)

Non-routine spacing geometry with off-spacing lateral requiring pre-approval of directional surveys, cementing details, and fracture stimulation procedures before completion. Wet shoe configuration is condition precedent to approval.

Permit conditioned on as-built directional survey, production liner and cementing details, and fracture stimulation procedures submitted for prior approval before completing well where wellbore portions approach within 500 feet of spacing unit boundary. Operator must indicate fracture initiation points in measured depth relative to boundary.

📄 APD Conditions of Approval, Page 2
📅 2026-01-15 (Exact confidence)

Exception location determination is conditioned on post-drilling technical submissions. This is regulator-imposed pre-completion gate tied to the specific U-turn lateral geometry that penetrates adjacent spacing unit.

Anticollision analysis dated 2025-09-23 evaluates proximity to MHA 3-27-34H-148-92 (Offset Well) and MHA 4-28-29H-148-92 with separation factors 11.136 and 3.759 respectively. Critical closest approach identified at MD 20,945.7' to sibling well MHA Bullsnake 4892 14-28 2BHP with separation factor 0.041 (Level 3 warning).

📅 2025-09-23 (Exact confidence)

Anticollision study is supporting technical justification for permit approval under horizontal drilling risk framework. Close-approach condition at MD ~20,946' to sibling well 2BHP demonstrates why construction commencement notification and real-time survey protocols are enforced.

Facility design employs indirect heater with setback exemption under NDIC Case No. 28949, Order No. 31500, permitting heater at 60 feet from wellhead and 21 feet from oil tank. This waives standard setback for production equipment.

📅 Unknown (Missing confidence)

Non-standard facility configuration requiring prior NDIC order. Permit approval implicitly references pre-existing exemption order, conditioning equipment placement on that waiver.

Federal minerals notification issued 2026-01-12 indicating spacing units may be subject to Federal permit. BLM coordination required for Sections 28 & 29-T148N-R92W per contact instruction to BLM Dickinson office (701) 227-7713.

Pre-approval regulatory alert tied to permit jurisdiction. Federal minerals coordination requirement imposes external approval contingency on NDIC-issued permit validity.

📖 Historical Context (3)

Filter sock disposal requirement per NDIC letter dated 2025-05-30 mandating leak-proof, covered, placard-marked containers on all wells spud after 2014-06-01. Operator acknowledges compliance in APD assertions.
📄 NDIC letter from Mark F. Bohrer dated 2025-05-30; APD Page 8 operator assertion confirming filter sock container maintenance · 📅 2014-06-01
Ongoing operational obligation persisting through drilling, completion, and flowback phases. Non-compliance creates solid waste disposal violation liability under ND Admin Code 43-02-03-19.2 and ND Admin Code 33.1-20-02.1-01.

Operator certified no diesel-based stimulation fluids (CAS 68334-30-5, 68476-34-6, 68476-30-2, 68476-31-3, 8008-20-6) will be used in hydraulic stimulation. List provided in APD and standalone Oasis commitment letter.
📄 APD PROPOSED WORK section item 10; Oasis letter dated January 9th, 2026; Horizontal Drill Plan Page 6 of 7 · 📅 2026-01-09
Operational constraint on stimulation design enforced at completion stage. Restricts frac fluid chemistry and limits operator discretion in pump-down design for Stage 1 perforations.

Operator identified licensed cuttings disposal facilities (9 named: Chimney Butte Environmental, Dishon Disposal, Ideal Oilfield Disposal, IHD Solids Management, Petrocomp, Prairie Disposal, Secure Energy Services, Tervita) with requirement to use closest available facility. Cuttings from invert mud system (70/30 interval 2052'-10483') require authorized disposal.
📄 Horizontal Drill Plan Page 7 of 7 and Oasis standalone letter Page 1 of 2; APD confirms closed mud system with no cuttings pit · 📅 2026-01-09
Ongoing solid waste management obligation. Well cannot achieve final plugging/abandonment approval without documented cuttings disposal at licensed facility. Inventory of pre-approved facilities locks operator into regulated disposal chain.

🔧 Operator Pattern

Oasis Petroleum operates multiple wells on same pad and adjacent spacing units within Bullsnake field. Operator demonstrates compliance infrastructure for federal/Indian lands permitting, anti-collision protocols, and facility exemption management.
MHA Bullsnake 4892 14-28 2BHP and 3BX wells on same pad (documented in survey plats and Anticollision Report); operator holds NDIC facility exemption (Case 28949); operator self-represents as adjacent spacing unit operator eligible for off-spacing waiver under Order 31848; operator filed January 9, 2026 waiver request referencing that adjacency; Oasis is subsidiary of Chord Energy (noted in operator letter).

Confidence: High
Well file contains explicit permit approval letter dated 2026-01-15, detailed APD with comprehensive stipulations tied to Commission Order 34129, engineer-signed anticollision analysis with specific separation metrics, supporting technical documents (Horizontal Drill Plan, survey plats, directional geometry), pre-approval regulatory notifications (BLM, NDIC), and operator waiver request with clear citation to regulatory precedent. No material dates are missing or inferred. Permit conditions are granular and directly tied to well geometry (off-spacing lateral, wet shoe, Level 3 anticollision risk to sibling well) and regulatory orders (ICO 34129, Case 28949, Order 31848, Order 31500).
