📊 Signals (6)

Tier	Signal	Date	Service Impact
Tier 2	Suspension of Drilling (SOD) request for up to 90 days to use a smaller rig for surface hole only, then move off and bring larger rig later.⏰ TIME-SENSITIVE 📄 Sundry Form - Request for Consideration/Waiver - Suspension of Drilling Reveals a staged, cost-saving drilling strategy: spud with a small rig (3-5 days), set surface casing, suspend, then bring Nabors X28 rig within 90 days. Creates two distinct rig mobilization/demobilization events and a window for surface casing services separate from main drilling.	2025-02-25	Drilling Rigs
Tier 2	Use of a 'wet shoe' sub on the 4-1/2" liner with intentional 2 bbl over-displacement to allow fracking out the shoe. 📄 Drilling Prognosis - Completion Equipment section Non-standard cementing/completion design. Wet shoe sub with rupture pins allows first frac stage to be pumped out the shoe, enabling closer wellbore placement to section line (150 ft setback).	Unknown	Completions / Frac
Tier 3	Lateral drilling encountered Lower Bakken Shale at 23,644' MD, leading to a sidetrack operation. 📄 Geologic Summary - Lateral section Unplanned geological event (drilling out of zone) required a sidetrack. Operation involved troughs, time drilling, and slides from 21,251' MD to 21,336' MD. Indicates geo-steering challenges or formation dip changes.	2025-11-23	Directional Drilling
Tier 3	MWD tool failure at 21,763' MD led to trip out of hole (TOOH) and troubleshooting attempts before sidetrack decision. 📄 Geologic Summary - Lateral section Tool failure caused non-productive time and preceded the sidetrack operation. Multiple downlink attempts failed, indicating a persistent tool issue, not a communication glitch.	2025-11-20	Drilling Rigs
Tier 3	Mandatory sample collection program dictated by NDIC with specific intervals (30' vertical/curve, 200' lateral) and archiving at Hess Houston and NDGS library. 📄 NDIC Letter - Cores and Samples Regulatory mandate overrides operator discretion. Requires specific sampling protocol and dual archiving (operator and state). Creates a fixed workflow for mudlogging/geological services.	2025-02-11	Mud / Fluids
Tier 3	Open hole log waiver granted based on offset well within one mile. 📄 Sundry Form - Open Hole Log Waiver Operator avoided routine open hole logging, reducing time and cost. Relies on offset data (STEEN 149-101-13-24-1H) and only ran GR-CBL from TD to surface. Indicates high confidence in subsurface model in this area.	2025-02-06	Regulatory / Permitting

💡 Operator Intent

Aggressive pad development and unit drainage by drilling long, multi-section laterals from a single pad targeting off-spacing units.

Well is part of a 7-well pad (BW-IDA-1416H series & 2321H series). Surface Use Agreement explicitly grants right to drill 'off lease' wells into Sections 14, 15, 16, 21, 22, 23. Lateral azimuth 261.12° drills westbound into Section 21. Anti-collision report shows tight spacing with many offset wells.
Optimize well construction cost and efficiency through non-standard regulatory approvals and engineered designs.

Secured waivers for open hole logs and a Suspension of Drilling order. Use of wet shoe sub design to minimize setback distance. Staged rig approach (small rig for surface) to save cost.
Maintain strong regulatory compliance and environmental stewardship as a standard practice.

Explicit adherence to NDIC sample collection and archiving mandates. Closed mud system with no cuttings pit per permit stipulations. Affidavit confirming no diesel fuels in hydraulic fracturing. Planned hauling of cuttings to approved facility.

🔧 Service Operator Relevance

Drilling Rig Services (Small & Large)

Two-phase rig strategy: immediate need for a small rig for surface hole (as per SOD request), followed by mobilization of Nabors X28 within a 90-day window. Creates sequential opportunities.

Directional Drilling / Geo-steering / MWD

Sidetrack event shows geo-steering challenges in the Middle Bakken lateral. MWD tool failure indicates potential need for more reliable tools or services. High anti-collision risk on pad demands precise surveying and real-time monitoring.

Cementing & Liner Services

Non-standard wet shoe sub design for the 4-1/2" liner requires specialized cementing execution to enable 'frac out the shoe'. Centralizer placement is highly detailed and zone-specific.

Mudlogging & Geological Services

Mandated sample collection at strict intervals (30'/200') creates fixed service scope. Dual archiving requirement (Hess Houston & NDGS) adds logistics complexity.

Civil Construction & Pad Building

Pad is engineered with specific grading, drainage, and facility layout by KLJ Engineering. Construction quantities are detailed (e.g., 27.74 acres disturbance, 131,908 CY excavation).
