📊 Signals (7)

Tier	Signal	Date	Service Impact
Tier 2	Wet shoe configuration on production liner, intentionally over-displaced by 7 barrels to create uncemented annulus for toe initiation. 📄 Discussion section in permit application Non-standard liner design allowing wireline pump-down of first-stage perforating guns, avoiding more expensive tubing or tractor methods.	Unknown	Completions / Frac
Tier 3	Surface Use Agreement executed with landowner for drilling into off-lease units from pad location. 📄 Affidavit Affirming Surface Use Agreement dated February 26, 2026 Legal arrangement enabling horizontal reach into adjacent units, with landowner awareness.	2026-02-26	General Oilfield Services
Tier 3	Waiver requested for notification to adjacent operator under Order No. 31973, as Oasis operates both the subject and adjacent spacing units. 📄 Letter dated January 6, 2026, and Affidavit dated February 26, 2026 Demonstrates operator's control over multiple units, enabling horizontal drilling from outside the target spacing unit without external notifications.	2026-01-06	Regulatory / Permitting
Tier 3	Exemption for indirect heater setback under NDIC Case No. 28949 Order No. 31500, allowing placement within 60 feet of wellhead and 21 feet of oil tank. 📄 Facility Statement Regulatory variance for facility design, prioritizing compact pad layout over standard setbacks.	Unknown	General Oilfield Services
Tier 3	Anti-collision measures include real-time corrected surveys, 1.2 separation safety factor, gamma ray signatures for wellbore identification, and surveys every 93-100 feet increasing as needed. 📄 Anti-Collision Statement Enhanced safety protocols beyond basic requirements, using advanced surveying and logging for collision avoidance.	Unknown	Directional Drilling
Tier 3	Pre-selected licensed facilities for solid drill cuttings disposal: Chimney Butte Environmental LLC, Dishon Disposal Inc, Ideal Oilfield Disposal LLC, IHD Solids Management LLC, Petrocomp, Prairie Disposal LLC, Secure Energy Services, Tervita Corporation. 📄 Licensed Facilities for Solid Drill Cuttings Disposal section Vendor ecosystem locked in for waste management, with closest facility to be used.	Unknown	General Oilfield Services
Tier 3	Commitment to no diesel-based stimulation fluids, excluding CAS numbers 68334-30-5, 68476-34-6, 68476-30-2, 68476-31-3, and 8008-20-6. 📄 Diesel Based Stimulation Fluids/Compounds section Explicit avoidance of diesel compounds in fracturing, aligning with environmental regulations and operator preferences.

💡 Operator Intent

To efficiently develop multiple horizontal wells from a single pad outside the target spacing unit, leveraging self-operated adjacent units.

Waiver for adjacent operator notification and Surface Use Agreement for off-lease drilling.
To optimize completion costs through innovative liner design and fluid choices.

Wet shoe configuration for wireline perforating and exclusion of diesel-based stimulation fluids.
To prioritize environmental compliance and regulatory efficiency in operations.

Pre-selected disposal facilities, no diesel fluids, and indirect heater exemption.

🔧 Service Operator Relevance

Directional drilling and surveying services

Anti-collision protocols require frequent surveys and real-time corrections, with permit approval in February 2026 signaling imminent drilling start.

Waste disposal and environmental services

Mandatory on-site filter containers and pre-selected disposal facilities align with spud timing post-permit approval.

Completion and stimulation services

Wet shoe design and non-diesel fluid commitment indicate specialized completion needs following drilling phase.
