Target Formation: Middle Bakken
Permit Explained: Yes

📋 Permit Cycle Assessment

The permit approval for GROVE 5892 31-33 6BX is directly explained by five time-bound signals: (1) Commission Order No. 34892 establishing the 500-foot drilling corridor and 150-foot setback constraints that govern lateral placement; (2) the Bakken Setback Summary Statement justifying east setback via wet shoe cement configuration; (3) closed mud system requirement; (4) remote shutoff device mandate; and (5) operator waiver granted for Order No. 31848 notification requirement due to Oasis Petroleum's control of the adjacent spacing unit. All signals are structural or event-based and directly condition or justify the approval. The anticollision analysis and engineering documents (well planning report, pad layout, access road design) provide supporting technical justification for the planned wellbore path but do not independently explain the permit action—they support the pre-approval engineering that the permit conditions reference.

🔍 Permit Cycle Signals (5)

Commission Order No. 34892 approval granted with mandatory drilling corridor constraint (500-foot corridor, east-west axis) and 150-foot setback from section boundaries within 5120-acre spacing unit

Direct

📄 Permit Information / Stipulations section, first stipulation entry
📅 Unknown (Missing confidence)

Directly conditions wellbore geometry approval; specifies binding spatial limits on lateral placement that differentiate this permit from routine approvals and require operator adherence during drilling execution

Production liner cemented in lateral with wet shoe configuration and ability to frac out shoe—basis for east setback approval per Bakken Setback Summary Statement

Supporting

📄 Stipulations section, 'Bakken Setback Summary Statement' entry
📅 Unknown (Missing confidence)

Technical justification for non-standard setback modification; wet shoe design explicitly conditions permit approval and ties to completion strategy

Closed mud system with no cuttings pit—permit review policy condition

Direct

📄 Stipulations section, 'Permit Review Policy' entry (mud system)
📅 Unknown (Missing confidence)

Environmental control condition tied to permit approval; operationally binding during drilling phase

Remote or automatic shutoff devices required on all equipment—permit review policy condition

Direct

📄 Stipulations section, 'Permit Review Policy' entry (safety devices)
📅 Unknown (Missing confidence)

Safety device mandate; standard but explicitly stated as condition of approval

Operator waiver request granted on notification to adjacent operator per Order No. 31848 because Oasis Petroleum is operator of adjacent spacing unit

Direct

📄 December 17, 2025 letter from Ryan Emery, Chord Energy; addresses wellbore traversal through adjacent spacing unit
📅 2025-12-17 (Exact confidence)

Non-routine waiver directly justifying permit approval for wellbore geometry that crosses spacing unit boundary; demonstrates operational control and eliminates notification requirement

📖 Historical Context (4)

Indirect heater setback exemption from NDIC under Case No. 28949 Order No. 31500 allowing placement within 60 feet of wellhead and 21 feet of oil tank (versus standard setbacks)
📄 Facility Statement section (NEW WELL PAD CONSTRUCTION STATEMENT attachment) · 📅 Unknown; historical exemption predating current permit
Facility design constraint persisting through well construction and operation; affects pad layout and equipment positioning for this well pad complex; must be maintained during drilling and completion phase

Cottonwood-Bakken Pool definition: accumulation from 50 feet above Bakken top to above Birdbear Formation—establishes target interval and producible zone
📄 Stipulations section, 'NDIC Field Order Info' entry (pool definition) · 📅 Unknown
Establishes regulatory producible interval; conditions completion design, perforation strategy, and resource definition for this well; non-routine pool definition specific to this spacing unit

5120-acre spacing unit (vs. standard 2560-acre) consisting of Sections 33, 34, 35, 36 (T158N, R92W) and Sections 1, 2, 3, 4 (T157N, R92W)—non-standard density spacing
📄 Stipulations section, 'NDIC Field Order Info' entry (spacing unit); Federal Minerals email dated 1/14/2026 · 📅 Unknown; email reference 2026-01-14
Establishes regulatory drilling rights and obligations; affects future offset well development and spacing unit density; may constrain adjacent drilling by Oasis or other operators

Well location at NW % of SW % Section 33 (GROVE 5892 31-33 6BX) with bottomhole in SEC 36—wellbore crosses sections and spacing unit boundaries
📄 December 17, 2025 Chord Energy letter; well plats and planning report · 📅 2025-12-17
Defines regulatory jurisdiction, operational risk (crossings into adjacent units), and drainage implications; affects future plugging, abandonment, and any unit modification requirements

🔧 Operator Pattern

Oasis Petroleum (Chord Energy subsidiary) operating multi-well pad development with coordinated spacing unit control and adjacent operator integration.
Well file shows GROVE FEDERAL 5892 31-33 PAD with six wells (GROVE and DUNLIN offsets) on single pad; operator controls both target spacing unit (5120-acre) and adjacent spacing unit (2560-acre per 1/14/2026 BLM notification); waiver request cites operator's own ownership of adjacent unit, eliminating third-party notification burden; anticollision analysis shows detailed offset well management across operator-controlled acreage with separation factors exceeding 1.2 safety threshold on all critical comparisons; planned 31,015-foot lateral indicates high-volume development strategy in Bakken target zone

Confidence: High
Well file contains explicit, dated permit stipulations and contemporaneous operational documents (December 2025 letters, November 2025 planning report). Permit approval date (07/25/2026 recorded in file header) is clearly marked as 'Dirt Work Date' and associated with NDIC Commission Order No. 34892. All permit-cycle signals are directly cited in the formal stipulations section of the APD or in regulatory correspondence pre-approval. No conflicting or ambiguous dates detected. Historical signals are clearly distinguished from permit-cycle justifications. OCR quality is high across regulatory text. The structure of the file (permit information block, stipulations, technical attachments, regulatory email) follows standard NDIC filing protocol.
