Target Formation: BAKKEN (Murphy Creek-Bakken Pool)
Permit Explained: Yes

Permit Cycle Assessment

The permit approval is directly explained by regulatory conditions tied to Commission Order 35252 (setbacks), aquifer location (requiring inspection and specific containment), and supporting waivers/affidavits for off-spacing and adjacent operator notification.

Permit Cycle Signals (5)

Conditional approval tied to Commission Order No. 35252, specifying a 150' setback from north/south boundaries and a 500' setback from east/west boundaries within the 1920-acre spacing unit.

Direct

Stipulations section, NDIC Field Order Info paragraph
Relative (referenced by permit) (Inferred confidence)

Permit is explicitly granted on the condition of compliance with this Order. The south setback is further justified by a production liner cemented in the lateral with a wet shoe.

Onsite inspection and site-specific stipulations required due to well location on an aquifer. Stipulations include Closed Mud System with no drilling pit and impermeable liner on the entire location.

Direct

Stipulations section, SPECIAL ATTENTION paragraph
Relative (permit approval date) (Inferred confidence)

A non-routine, site-specific regulatory requirement triggered by aquifer location, conditioning permit approval.

Operator must contact NDIC Field Inspector Nicole Ewoniuk prior to location construction.

Direct

Construction Commencement Notification paragraph
Relative (pre-construction) (Exact confidence)

A direct pre-construction condition tied to the aquifer stipulation and inspection requirement.

Waiver request for adjacent operator notification (per Order No. 31973) because Oasis is the operator of the adjacent spacing unit.

Supporting

Letter from Ryan Emery dated September 2nd, 2026
2026-09-02 (Exact confidence)

Addresses a specific regulatory requirement for off-spacing wells, justifying a waiver that facilitates permit approval.

Affidavit affirming a Surface Use Agreement is in place for drilling off-lease units from the pad location.

Supporting

Affidavit dated August 31st, 2026
2026-08-31 (Exact confidence)

Directly satisfies a regulatory condition ('Is the well located off-spacing?') noted in the operator assertions, required for permit approval.

Historical Context (2)

Aquifer location triggers persistent operational constraints: Closed Mud System with no drilling pit, impermeable liner on entire location, and mandatory pre-construction inspection.
Stipulations section, SPECIAL ATTENTION paragraph · Relative (permit approval)
These are non-standard, site-specific physical and procedural requirements that will govern all pad construction and drilling operations, imposing higher costs and regulatory oversight.

Order No. 31973 obligation for notifying adjacent operators when wellbore traverses an adjacent spacing unit.
Letter from Ryan Emery dated September 2nd, 2026 · Relative (referenced)
This is a standing regulatory obligation for any future wells drilled from this pad that enter off-lease units, requiring either notification or a justified waiver.

Operator Pattern

Operator utilizes standardized technical submissions (anti-collision statement, drilling program, wet shoe design) and proactively seeks waivers for routine regulatory hurdles (log waiver, adjacent operator notification).
Included anti-collision statement, detailed drilling program with wet shoe configuration, waiver request for logs, and waiver request for adjacent operator notification citing ownership of adjacent unit.

Confidence: High
The permit document and attached submissions contain clear, direct regulatory conditions (Order 35252, aquifer stipulations) and contemporaneous supporting documents (affidavit, waiver letter) dated just prior to permit approval, providing a complete explanation.
