Permit Explained: Yes

Permit Cycle Assessment

The permit is explained by contemporaneous documents. Regulatory Order 35252 and associated stipulations directly condition approval. The technical submission for the 'wet shoe' completion design supports the permit's stated north setback justification.

Permit Cycle Signals (4)

Commission Order No. 35252 approval for the well includes specific 150' north & south and 500' east & west setbacks within the 1920-acre spacing unit, noting the north setback is based on a production liner cemented in the lateral with a wet shoe.

Unknown (Missing confidence)

This order directly authorizes drilling and imposes geometry-specific constraints tied to the well's completion design.

Special attention stipulation requiring an onsite inspection and closed mud system with no drilling pit and impermeable liner due to well location on an aquifer.

Unknown (Missing confidence)

Imposes non-routine, site-specific environmental controls that condition permit approval.

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

Unknown (Missing confidence)

A direct, pre-construction regulatory action required for permit execution.

Technical submission includes a detailed 'wet shoe' completion configuration (cement over-displaced to create uncemented annulus) referenced in the permit's north setback justification.

2026-09-02 (Exact confidence)

This engineering design directly supports and justifies the permit condition related to the production liner and north setback.

Historical Context (2)

The well location is on an aquifer, triggering permanent special attention stipulations (closed mud system, impermeable liner, onsite inspection) that persist for all operations.
Permit Information page, STIPULATIONS - SPECIAL ATTENTION section · Unknown
This is a persistent site-specific environmental constraint affecting all future drilling, completion, and location activities at this pad.

An anti-collision statement is filed, detailing protocols (1.2 separation factor, survey frequency, gamma ray monitoring) due to proximity to existing wellbores.
Attachment section, Anti-Collision Statement · Unknown
Establishes an ongoing operational safety requirement for drilling this wellbore in a congested field, affecting future drilling execution and survey management.

Operator Pattern

Operator (Oasis/Chord) routinely utilizes detailed technical planning (wet shoe design, anti-collision protocols) and seeks regulatory waivers (notification waiver for adjacent unit).
The filing includes a comprehensive technical appendix with well diagrams and statements. A waiver request for adjacent operator notification is included, citing the operator's control of the adjacent unit.

Confidence: High
Key permit-conditioning documents (Order 35252, stipulation letter) are present within the permit file. Technical submissions are contemporaneous and directly referenced by permit conditions. No critical dates appear to be missing for core permit-cycle analysis.
