📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 1	Variance requested for tubing/packer requirement under NDAC 43-02-03-21, citing use of new #29 and 32# casing with API burst rating of 11,220 psi, safety factor of 0.85, immediate detection of damage, low corrosion/erosion rates, and planned production equipment installation. 📄 Sundry Form for Well File No.: 41972 - Tubing/Packer Waiver Deviation from standard packer requirements for horizontal wells, justified by casing design and monitoring assurances, suggesting customized completion strategy to optimize costs or flowback operations.	2025-06-09	General Oilfield Services
Tier 3	Waiver requested for collection of drill cutting samples in vertical portion, citing use of samples from offset well Thunderbolt 10-12 1H (File #41970) for Base of Last Salt to planned curve Kick off Point, with resumption of 30' samples in curve and lateral sections. 📄 Sundry Form for Well File No.: 41972 - Drill Cutting Samples Waiver Non-standard regulatory waiver to reduce sampling frequency in vertical section by leveraging offset well data, potentially indicating cost-saving measures or operational efficiency in multi-well pad development.	2026-01-29	Regulatory / Permitting
Tier 3	Waiver requested for filter sock container requirement, stating no use of filter media during drilling, with exemption for drilling phase only. 📄 Sundry Form for Well File No.: 41972 - Filter Sock Container Waiver Exemption from standard waste management container due to non-use of filtration systems, indicating simplified drilling fluid handling and potential focus on closed-loop or alternative mud systems.	2025-06-12	Mud / Fluids
Tier 3	Request for suspension of drilling for up to 90 days to use smaller rig for surface hole, set casing, and move off, with larger rig to follow within 90 days, to achieve cost and time savings without altering lease obligations.⏰ TIME-SENSITIVE 📄 Sundry Form for Well File No.: 41972 - Suspension of Drilling Strategic suspension to utilize phased rig deployment, avoiding deviation in surface hole and emphasizing cost-efficiency in multi-rig operations on pads.	2025-06-11	Drilling Rigs
Tier 3	Waiver for open hole logs under DMR Rule 43-02-03-31, citing sufficient logs from offset well 3B Myron 9-4 3H (NDIC File #28232) within 1 mile, with GR-CBL planned from TD to ground level. 📄 Sundry Form for Well File No.: 41972 - Open Hole Log Waiver Reliance on offset well logs to skip open hole logging, potentially reducing logging costs while maintaining regulatory compliance through planned cased hole logs.	2025-06-06	Regulatory / Permitting

💡 Operator Intent

To minimize operational costs and expedite development through regulatory waivers and phased drilling strategies.

Multiple waivers requested for samples, logs, containers, and tubing/packer, plus suspension of drilling to use smaller rigs initially, all justified by cost/time savings without compromising safety or compliance.
To leverage offset well data and pad efficiencies for streamlined operations in a multi-well development.

Waivers citing use of samples and logs from nearby wells (Thunderbolt 10-12 1H and 3B Myron 9-4 3H), and shared pad location for four wells targeting Middle Bakken.

🔧 Service Operator Relevance

Drilling and completion services

With drilling completed on October 18, 2025, and well awaiting completion, immediate opportunities in flowback, production setup, and monitoring as per waiver assurances for rapid equipment installation.

Waste management and disposal

Closed-loop cuttings disposal to Dishon Disposal ongoing during drilling; post-drilling, focus on filter-free systems and leak-proof containers if filtration used in completion/flowback.

Logging and geological consulting

Cased hole GR-CBL logging planned post-TD; geological steering by Core Geologic completed, but data integration from offsets signals ongoing analytical services.
