Permit Explained: Yes

Permit Cycle Assessment

The permit approval is directly explained by a Commission Order (34458) conditioning approval on specific setbacks, with a non-routine north setback justified by a wet shoe liner completion. Supporting pre-permit submissions include a waiver request for adjacent operator notification and an anti-collision report mitigating close approaches.

Permit Cycle Signals (4)

Permit approval conditional on compliance with Commission Order No. 34458, requiring wellbore setbacks of 150' from north & south boundaries and 500' from east & west boundaries within the 1280-acre spacing unit.

Unknown (Missing confidence)

Permit explicitly ties approval to a specific Commission Order (No. 34458), making it a direct regulatory condition rather than standard setback language.

North setback (150') based on production liner cemented in lateral with wet shoe configuration and ability to frac out the shoe.

Unknown (Missing confidence)

Explicitly links a specific well geometry and completion technique (wet shoe liner) to a modified setback requirement, justifying non-standard north setback.

Waiver request for adjacent operator notification (Order No. 31848) because Oasis is the operator of the adjacent spacing unit.

2026-09-02 (Exact confidence)

Direct regulatory waiver request submitted pre-permit (9/2/2026) to satisfy a condition of approval (Order No. 31848) for a wellbore traversing adjacent unit.

Anti-collision report identifies close approaches with offsets (e.g., 30.72' from LOVEGOOD FEDERAL 4595 42-19 2BX) and cites specific separation factors.

2026-08-17 (Exact confidence)

Technical submission justifying wellpath safety and anti-collision mitigation, a prerequisite for permit approval of closely spaced laterals.

Historical Context (3)

Wet shoe liner configuration with intentional 400' of uncemented annulus at toe for wireline perforating.
Wet Shoe section in drilling program · Unknown
Specific completion design imposes operational constraints for stage initiation and cement evaluation, affecting future completion procedures.

Anti-collision constraints with multiple nearby wells (e.g., Franchuk 34-19SWH at 47.81' separation).

Persistent proximity to existing wellbores mandates strict survey monitoring and real-time anti-collision protocols during drilling execution.

Filter sock leak-proof container requirement per NDAC 43-02-03-19.2, effective June 1, 2014.

Ongoing regulatory obligation for waste management during drilling, completion, and flowback phases.

Operator Pattern

Operator (Oasis/Chord Energy) utilizes standardized wet shoe liner designs and detailed anti-collision planning for multi-well pads.
Drilling program includes wet shoe design details; anticollision report shows systematic evaluation of nearby wells from same pad (Chang 2BX, Lovegood series).

Confidence: High
Permit stipulations directly reference Order 34458 and a specific well geometry. Supporting documents (waiver request, anticollision report) are dated pre-approval and clearly relevant to permit conditions.
