📊 Signals (10)

Tier	Signal	Date	Service Impact
Tier 3	Permit submitted on 01/22/2026 and approved on 02/06/2026⏰ TIME-SENSITIVE 📄 Submitted By and Approved By sections Rapid approval timeline (14 days) indicates urgency or streamlined regulatory process	2026-01-22	General Oilfield Services
Tier 3	Wet shoe with ability to frac out the shoe on production liner 📄 Conditions of Approval and Proposed Drilling Plan Specific completion design choice for toe initiation, not standard for all horizontals	Unknown	Completions / Frac
Tier 3	Closed mud system required with impermeable liner on entire location 📄 Aquifer stipulation Environmental stipulation mandates advanced drilling fluid management, beyond basic pit restrictions	Unknown	Mud / Fluids
Tier 3	Operator must not intentionally deviate in any portion of the 17-1/2-inch surface hole 📄 Conditions of Approval Non-standard restriction on drilling trajectory, suggesting unique geological or regulatory constraints	Unknown	Directional Drilling
Tier 3	Mud logger required on-site from ground level to total depth of 17-1/2-inch surface hole at no greater than 30' sample intervals 📄 Conditions of Approval Exceeds standard logging requirements, indicating heightened regulatory scrutiny or operator choice for enhanced monitoring in surface hole	Unknown	Mud / Fluids
Tier 3	Cement bond logs required on 13-3/8-inch, 9-5/8-inch, and 7-inch casings with zero-pressure pass on surface casing 📄 Conditions of Approval Multiple CBL runs with specific verification steps exceed typical cementing oversight, pointing to operator intent for robust zonal isolation	Unknown	General Oilfield Services

Tier 3	Line heater manufactured by either Steffes or JW Williams 📄 Proposed Work Facilities Pre-specified vendors for facilities, revealing ecosystem preference	Unknown	General Oilfield Services
Tier 3	No diesel-based compounds allowed in hydraulic stimulation 📄 Proposed Drilling Plan Prohibits specific CAS numbers in frac fluids, signaling operator preference for alternative chemistries	Unknown	Completions / Frac
Tier 3	Ball seat included for testing liner 📄 Proposed Drilling Plan Specific tool for liner integrity testing, indicating advanced completion planning	Unknown	General Oilfield Services

💡 Operator Intent

Pursue horizontal drilling with enhanced monitoring and environmental controls to minimize regulatory risks

Mud logger requirement, no intentional deviation, closed mud system, and aquifer stipulations
Implement advanced completion design for efficient toe initiation and stimulation

Wet shoe with frac-out capability, ball seat for liner testing, and prohibition on diesel compounds
Ensure timely project execution with neighbor notifications and precise boundary adherence

Acknowledgment of 31-day notice for adjacent completions and specific perf points relative to section lines

🔧 Service Operator Relevance

Directional drilling and surveying

With approval in February 2026, drilling could commence soon; non-deviation rule requires high-precision services

Cementing and logging

Multiple CBL requirements post-approval indicate immediate need for specialized cement verification services

Completion and stimulation

Wet shoe and frac-out design signals upcoming toe prep and hydraulic fracturing opportunities following drilling
