📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 2	Suspension of drilling requested for up to 90 days to use a smaller rig for surface hole only, then move off and bring larger rig within 90 days.⏰ TIME-SENSITIVE 📄 WELL SUNDRY FORM - Request for Consideration/Waiver - Suspension of Drilling Operator plans a two-rig strategy: small rig drills surface hole with freshwater mud, sets casing, then leaves. Larger rig must move on within 90 days to complete well. Reveals cost/time optimization and creates a defined window for rig and service mobilization.	2025-05-12	Mud / Fluids
Tier 3	MWD gamma tool failure during lateral drilling at 26,606' MD; decision made to continue drilling to TD without it. 📄 GEOLOGIC SUMMARY - Lateral section Real-time geosteering capability impaired late in lateral. Operator chose to proceed based on existing data, indicating risk tolerance and confidence in well path.	2025-12-24	General Oilfield Services
Tier 3	Regulatory stipulation: 'Due to the possibility of severe casing wear... surface holes are not to be intentionally deviated.' 📄 SUNDRY FORM FOR WELL FILE NO.: 41893 - REVIEWER COMMENTS NDIC imposes a non-standard design constraint based on casing wear risk, limiting directional flexibility in the surface section.	2025-05-12	Directional Drilling
Tier 3	Open hole log waiver approved based on offset well data, only cased hole CBL/GR/CCL required. 📄 WELL SUNDRY FORM - Open Hole Log Waiver Operator avoids routine open hole logging, reducing time and cost. Indicates high confidence in offset well (HODENFIELD 15-33H) data for formation tops.	2025-05-09	Regulatory / Permitting
Tier 3	Specific sample collection and archiving protocol: two sets of samples to Hess Houston and ND Geological Survey Core Library. 📄 GEOLOGIC SUMMARY Explicit dual archival requirement beyond standard. Indicates operator's commitment to data preservation and regulatory compliance for core library.	Relative	General Oilfield Services

💡 Operator Intent

Optimize pad drilling efficiency and cost through sequenced rig operations and shared services.

Two-rig strategy (small rig for surface, large rig for TD), skid operations between wells on pad (GO PETERS H5 to H4), and use of shared mudlogging/geology team across pad wells.
Minimize operational time and cost by waiving non-essential data acquisition.

Approved waiver for open hole logs, relying on offset well data. Decision to continue drilling after MWD gamma tool failure instead of tripping for repair.
Ensure long-term data preservation and regulatory compliance for geological analysis.

Mandated dual archival of samples to Hess Houston and ND Geological Survey Core Library with specific collection intervals (30' vertical/curve, 200' lateral).

🔧 Service Operator Relevance

Rig & Drilling Services

Two-phase rig requirement: small rig for immediate surface hole (planned start ~9/24/2025) and larger rig (Nabors X27) must be mobilized within 90 days after surface spud. Rig skidding operations on pad indicate sequential drilling.

Cementing & Casing

Specific cementing volumes and centralizer placement detailed for surface, production, and liner strings. Surface casing must be called in immediately after spud and plug bump per regulatory comment.

Sample Management & Shipping

Samples must be washed, dried, boxed, and shipped to two locations (Hess Houston and ND Core Library) within 30 days of drilling completion (TD reached 12/25/2025).

Directional Drilling & Surveying

Surface hole deviation prohibited per regulatory stipulation due to casing wear concerns. Anti-collision planning critical with multiple wells on pad and nearby existing wellbores.

Well Control & BOP Services

Specific BOP stack configuration (11" 5M) and testing protocol (function test every 7 days, pressure test every 21 days) mandated. Choke manifold includes remote operated hydraulic choke.
