Permit Cycle Assessment

The well file contains contemporaneous documents (waiver requests, APD renewal) that justify specific, non-routine conditions for the permit cycle anchored around 2026. However, the file lacks a direct regulatory order or stipulation letter issued specifically for the 2026 permit renewal date that explicitly restates all binding conditions.

Permit Cycle Signals (4)

APD renewal request with all stipulations and conditions of approval from the original permit and modifications applying.

Direct

Sundry Form ID: 301165 (Permit Renewal)
2026-03-02 (Exact confidence)

Directly references the conditions governing the renewed permit, reactivating all prior regulatory constraints.

Request for waiver to visual inspection and photograph requirement of top intermediate casing joint and wellhead flange, proposing wireline logging as a superior, quantitative alternative.

Supporting

Sundry Form ID: 330398 (Request for Variance/Waiver)
2026-08-05 (Exact confidence)

A non-routine regulatory waiver request that modifies standard well construction verification requirements, requiring explicit approval.

Request for waiver for drill cutting sample collection in the vertical portion, citing collection from a sister well (Shorthorn 3-27 1H) on the same pad.

Supporting

Sundry Form ID: 330397 (Drill Cutting Samples Waiver)
2026-08-05 (Exact confidence)

A non-routine waiver from standard geologic sample collection procedures, requiring justification and approval.

Request for waiver to adjust directional survey frequency from 30' to 45' increments if 45' drill pipe is used.

Supporting

Sundry Form ID: 330396 (Directional Survey Frequency Waiver)
2026-08-05 (Exact confidence)

A technical waiver request that conditions the approved drilling and surveying program on specific equipment.

Historical Context (3)

Approval conditioned on 150' setback from N/S boundaries and 500' setback from E/W boundaries within the 1280-acre spacing unit, with the north setback based on a wet shoe for fracturing.
Original Permit Stipulations (Approved 2020-03-09) · 2020-03-09
These are permanent, geometry-specific location constraints tied to the well's approved spacing unit (Order 30485) that dictate wellbore placement and completion design for the life of the well.

Waiver to the requirement for an on-site filter sock container, approved for all phases, with waste transported to central SWD facility bins.
Sundry Form ID: 268263 (Filter Sock Container Waiver) · 2025-09-08
This is an ongoing operational waiver that modifies standard waste handling procedures for the well's entire lifecycle, from drilling through production.

Anti-collision statement identifies offset wells (Angus 34-27 4TFH, Nelson 3-10 2TFH, Gust 2-11 2H) requiring temporary abandonment (TA) with pressure monitoring prior to completion operations.
Anti-Collision Statement (dated 2020-01-06) · 2020-01-06
This creates a forward operational obligation to manage interference risks with specific, nearby wells during future hydraulic fracturing operations.

Operator Pattern

Frequent use of regulatory waivers for operational flexibility (casing inspection, cuttings sampling, survey frequency, filter sock handling).
Multiple Sundry Forms (IDs: 330398, 330397, 330396, 268263) document approved waiver requests for non-routine procedures across multiple wells/permits.

Confidence: High
Key permit-cycle documents (renewal, waivers) are clearly dated and relevant. Historical stipulations are explicitly referenced. No dates were invented; missing specific permit issue date for 2026 renewal is handled via relative dating in assessment.
