📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 2	Operator requested and received approval for suspension of drilling operations for up to 90 days after spudding surface hole with a smaller rig, with intent to bring larger rig later to complete well.⏰ TIME-SENSITIVE 📄 Suspension of Drilling Sundry Form (FORM ID: 247096) Reveals a staged drilling approach to achieve cost and time savings. Creates a 90-day window between surface casing and full-depth drilling, impacting rig scheduling and service timing.	Relative	Drilling Rigs
Tier 3	Approved spud date is in the future (9/29/2025), with detailed cementing report submitted showing adjusted depths for 'big rig' and volumes received vs. calculated.⏰ TIME-SENSITIVE 📄 Notification of Work Performed - Spud Date Sundry Form Well file contains a future spud date and associated operational details, indicating advanced planning and regulatory filing for work not yet performed. Cement report shows field adjustments.	2025-09-29	Drilling Rigs
Tier 3	Operator is required to collect and submit drill cuttings samples starting at the Base of the Last Charles Salt at specified intervals, and any cores, within strict timelines (30 days for samples, 180 days for cores).⏰ TIME-SENSITIVE 📄 Letter from ND Geological Survey regarding Cores and Samples Non-routine, prescriptive sample collection mandate with defined start point and submission deadlines. Indicates regulatory or geologic interest in specific formations.	2025-05-19	General Oilfield Services
Tier 3	Operator requested and received waiver for open hole logs, relying on offset well HICKEL 15-35H (NDIC# 19066) within a mile, and will only run GR-CBL from TD to surface. 📄 Request for Consideration/Waiver - Open Hole Log Waiver (FORM ID: 247104) Indicates a deviation from standard data acquisition, reducing logging scope. Shows reliance on existing subsurface data from a specific offset, suggesting confidence in the area's geologic predictability.	2025-05-13	Regulatory / Permitting
Tier 3	Surface hole is not to be intentionally deviated due to risk of severe casing wear during drilling of vertical and curve sections. 📄 Suspension of Drilling Sundry Form and Permit Stipulations Explicit operational constraint driven by casing wear concerns, not a routine regulatory requirement. Indicates specific geomechanical or historical challenges in the area.	Unknown	Directional Drilling

💡 Operator Intent

To develop a multi-well pad efficiently using a cost-optimized, staged drilling strategy.

Request for suspension of drilling outlines plan to drill surface hole with small rig, set casing, then return with larger rig within 90 days. Surface Use Agreement affidavit states intent to operate three other wells (GO-WOLLA-157-97-3422H-1, -4, -5) from the same location.
To leverage existing subsurface data to reduce logging costs and accelerate operations.

Waiver for open hole logs based on offset well HICKEL 15-35H within a mile, stating it has sufficient logs to establish formation tops.
To proactively manage anti-collision risks in a densely drilled area.

Anti-collision statement details multiple precautions: certified well planner guidance, real-time corrected surveys, 1.5 separation factor standard, use of Gamma ray for geo-steering, and increased survey frequency near existing wellbores.
To maintain operational flexibility for future infill drilling on the pad.

Facility plot plan includes notes for 'possible future expansion' and design elements like JB Rack stands to be installed for use by infill wells.

🔧 Service Operator Relevance

Pad Construction & Civil Earthwork

Detailed engineered pad design with extensive quantities (22,278 CY excavation, 987 LF access road) is approved. Construction must precede spud date of 9/29/2025.

Rig Mobilization/Demobilization & Specialized Drilling Services

Two-phase rig schedule: initial small rig for surface hole (implicit), then larger rig (potentially NaborsX28 per drilling prognosis) within 90 days post-spud. Requires precise timing and possibly different rig contractors.

Cementing & Casing Centralization

Detailed centralizer placement schedules for surface, production, and liner casing indicate specific, non-standard centralization requirements, especially through salt zones.

Sample Collection & Logistics

Mandatory sample collection from Base of Last Charles Salt with 30-day submission deadline post-drilling. Requires on-site sample handling and shipping coordination.

Directional Drilling & Surveying

Strict 'no deviation' order in surface hole requires precise vertical drilling. Subsequent build and lateral sections require anti-collision management and specific survey frequencies (every 93-100 ft, increasing as needed).
