Permit Cycle Assessment

The permit file contains contemporaneous documentation explaining the permit action. Direct regulatory conditions (Order 35252 setbacks, aquifer stipulation) and supporting justifications (wet shoe for south setback, off-lease SUA affidavit, adjacent operator waiver) are present and time-bound to the permit.

Permit Cycle Signals (5)

Permit approval is conditioned on Commission Order No. 35252, requiring wellbore portions not isolated by cement to maintain specific setbacks (150' N/S, 500' E/W) within the 1920-acre spacing unit.

Direct

Permit Information - STIPULATIONS - NDIC Field Order Info
Unknown (Missing confidence)

This is a direct, non-standard condition of approval tied to a specific Commission Order, establishing the legal framework for the permit.

Special Attention stipulation: An onsite inspection is required due to well location on an aquifer, mandating a closed mud system with no drilling pit, an impermeable liner, and additional site-specific stipulations at the Field Inspector's discretion.

Direct

Permit Information - STIPULATIONS - SPECIAL ATTENTION
Unknown (Missing confidence)

This is a direct, non-routine regulatory stipulation triggered by a specific site condition (aquifer location) and conditions the permit approval.

The south setback (150') is justified based on a production liner cemented in the lateral with a wet shoe and the ability to frac out the shoe.

Permit Information - STIPULATIONS - NDIC Field Order Info
Unknown (Missing confidence)

This directly explains the rationale for a specific permit condition (the south setback), linking it to the proposed well construction (wet shoe completion).

Affidavit affirming Surface Use Agreement executed for off-lease drilling from the pad location.

Supporting

Well File - Affidavit
2026-08-31 (Exact confidence)

This is a supporting document required for permit approval because the well is drilling 'off-lease' from the pad location, addressing a specific regulatory condition.

Waiver request for adjacent operator notification pursuant to Order No. 31973, as Oasis is the operator of the adjacent unit.

Supporting

Well File - Letter dated September 2nd, 2026
2026-09-02 (Exact confidence)

This is a supporting submission that justifies waiving a standard permit requirement (adjacent operator notification), directly facilitating the permit.

Historical Context (2)

Special Attention stipulation for aquifer location imposes persistent operational constraints: mandatory closed mud system, no drilling pit, impermeable liner, and ongoing Field Inspector discretion for site-specific requirements.
Permit Information - STIPULATIONS - SPECIAL ATTENTION · Unknown
These are not one-time permit conditions but ongoing operational obligations for location construction, drilling, and site integrity that must be adhered to throughout the well's execution phase.

The well is part of a multi-well pad (Gryffindor 4595 33-29 Pad) with several other proposed wells (Potter, Granger Federal, Dumbledore Federal series).
Various sheets (S-1A, S-3A, S-3B, Affidavit, C-2) · Relative
Future pad operations, scheduling, anti-collision management, and surface use are interdependent, creating persistent coordination obligations and shared infrastructure responsibilities beyond this single permit.

Confidence: High
The permit and associated documents (affidavit, waiver request) provide clear, direct regulatory conditions and supporting technical/legal justifications. Dates for supporting submissions are present. The separation between permit-cycle signals (anchored to approval conditions) and historical context (persistent pad obligations) is unambiguous.
