📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 2	Permit approval contingent on wet shoe liner configuration for east-west setback compliance, allowing over-displacement of cement to enable wireline perforating. 📄 Permit Stipulations, Page 2 of 10, Date 2/27/2026 Non-standard liner design to meet setback rules, avoiding more expensive tubing perforating methods.	2026-02-27	Completions / Frac
Tier 3	Requirement for submission of cores and samples to ND Geological Survey within specified timelines (30 days for samples, 180 days for cores) with potential civil penalty for non-compliance.⏰ TIME-SENSITIVE 📄 Letter from ND Geological Survey dated 3/2/2026 Imposes strict post-drilling regulatory deadlines not typical in all jurisdictions, indicating potential delays or costs if not met.	2026-03-02	General Oilfield Services
Tier 3	Surface Use Agreement executed for off-spacing horizontal drilling into adjacent units, with waiver of notification to adjacent operator since operator owns the unit. 📄 Affidavit Affirming Surface Use Agreement dated 26th of February, 2026; Letter to NDIC dated January 6, 2026 Enables drilling from outside spacing unit, reducing surface footprint but requiring landowner consent.	2026-02-26	Directional Drilling
Tier 3	Anti-collision report shows minimum separation factors as low as 1.077 with nearby wells, using gamma ray signatures and real-time surveys. 📄 Anti-Collision Statement and Report, Survey Program Date 12/3/2025 Tight proximity to offset wells requires advanced surveying and gamma logging, not routine in all Bakken operations.	2025-12-03	Directional Drilling
Tier 3	Explicit commitment to no diesel-based stimulation fluids, listing CAS registry numbers to avoid. 📄 Diesel Based Stimulation Fluids/Compounds section Voluntary avoidance of diesel in fracs, aligning with environmental preferences despite not mandated.	Unknown	Completions / Frac

💡 Operator Intent

To minimize completion costs by using wet shoe liner design for wireline perforating instead of tubing conveyance.

Permit stipulations specify wet shoe configuration to meet setbacks and enable economic toe initiation.
To pursue efficient multi-well pad development by drilling off-spacing with landowner agreements.

Surface Use Agreement for adjacent units and waiver of notification due to operator ownership.
To prioritize environmental compliance and operational safety through advanced anti-collision measures and diesel-free fracs.

Anti-collision report with gamma ray and real-time surveys; explicit avoidance of diesel-based fluids.

🔧 Service Operator Relevance

Directional drilling and surveying services

Anti-collision report indicates tight separations requiring frequent surveys (every 93-100 ft); opportunity for real-time MWD tools post-permit approval in late February 2026.

Waste disposal and environmental services

Pre-selected licensed facilities for cuttings; timing aligns with drilling start in approximately 30 days from permit approval (around March 2026).

Completion and stimulation services

Wet shoe design favors wireline perforating; diesel-free commitment opens doors for alternative fluid providers ahead of completion phase.
