📊 Signals (6)

Tier	Signal	Date	Service Impact
Tier 2	Cementing program for production liner specifies a 'wet shoe' design with ability to frac out of the shoe, and no bridge plug between perf and shoe. 📄 GEOLOGIC WELL PROGNOSIS - Completions Information Specific cementing and completion design choice that affects stimulation operations and well integrity management.	Unknown	Completions / Frac
Tier 3	Operator requested and received waiver for open hole logs, relying on offset well Sather 1 (NDIC #10424) within a mile, with GR-CBL and CBL logs to be run instead. 📄 WELL SUNDRY FORM - Request for Consideration/Waiver Avoids standard open hole logging requirement, indicating reliance on existing data and potential cost/time savings. Signals operator confidence in subsurface predictability.	2026-07-01	Regulatory / Permitting
Tier 3	Spud notification confirms use of Nabors Rig #B27 (not the originally contracted Nabors B23 mentioned in APD). 📄 WELL SUNDRY FORM - Notification of Work Performed Rig change indicates possible fleet reassignment or operational adjustment; Nabors B23 was originally contracted.	2026-05-16	Drilling Rigs
Tier 3	APD renewal requested on 11/06/2025, extending permit expiration from 10/30/2025 for an additional year.⏰ TIME-SENSITIVE 📄 WELL SUNDRY FORM - Request to Perform Work (Permit Renewal) Indicates operator intent to delay spudding beyond original permit timeline, suggesting strategic pacing or pad sequencing adjustments.	2025-11-06	Drilling Rigs
Tier 3	Operator submitted a 'Drill-Back Offset Operator Notification' requesting waiver from NDIC Order No. 31973 because the adjacent spacing unit is also operated by Silver Hill. 📄 Drill-Back Offset Operator Notification letter Drill-back into adjacent unit owned by same operator simplifies regulatory process and indicates multi-unit development strategy.	2024-10-29	Regulatory / Permitting
Tier 3	Operator explicitly states they will not run a frac string; a caliper log will be submitted for NDIC approval prior to completions. 📄 GEOLOGIC WELL PROGNOSIS - Intermediate Hole Notes Non-standard completion approach; reliance on caliper log instead of frac string indicates alternative isolation or completion design.	Unknown	Completions / Frac

💡 Operator Intent

Execute multi-well pad development with precise anti-collision management and extended-reach drilling.

Anti-collision report references multiple offset wells on same pad (Double-R Leah, Double-R Paige) and nearby Tucson wells; drill-back notification indicates lateral extension into adjacent unit.
Optimize well construction costs by waiving standard open hole logs and forgoing frac string.

Log waiver request based on offset data; explicit statement not to run frac string, relying on caliper log and wet shoe design.
Maintain flexible drilling schedule with permit renewal and rig substitution.

APD renewal requested nearly a year after permit issue; spud notification shows different rig (B27) than originally planned (B23).

🔧 Service Operator Relevance

Cased-hole logging & cement evaluation

Open hole log waiver increases need for GR-CBL, CBL, and caliper logs to verify well integrity and obtain NDIC approval for completion.

Directional drilling & surveying

Complex pad with multiple wellbores and anti-collision concerns; ongoing need for precise surveying and trajectory control.

Cementing services

Specific wet shoe design and surface casing cementing require specialized expertise; American Cementing already used but potential for additional stages.

Waste transportation & disposal

Closed-loop system with designated disposal sites (Prairie Disposal, Indian Hills Disposal) requires continuous hauling and coordination.

Completion & stimulation design

Non-standard approach with wet shoe and no frac string creates opportunity for engineering firms specializing in alternative Bakken completion designs.
