📊 Signals (8)

Tier	Signal	Date	Service Impact
Tier 2	Approval conditional on 150' north/south and 500' east/west setbacks within 2560-acre spacing unit, with south setback based on production liner cemented in lateral with wet shoe and ability to frac out the shoe. 📄 Stipulations section, page 1 Specific geomechanical condition tied to completion design (wet shoe) for regulatory approval, indicating a tailored engineering solution to meet spacing requirements.	Unknown	Completions / Frac
Tier 2	Wet shoe configuration detailed: 400 ft of uncemented annulus at liner toe, over-displaced by 7 bbls to enable wireline pump-down perforating for toe initiation. 📄 Section 1.11 Wet Shoe and schematic Non-standard liner cementing design to facilitate cost-effective toe initiation, revealing a specific completion methodology choice.	Unknown	Completions / Frac
Tier 3	Drill-back notification provided to adjacent operator (Devon Energy) via email on February 11, 2026, as required for off-spacing unit drilling. 📄 AFFIDAVIT AFFIRMING DRILL-BACK NOTIFICATION Demonstrates regulatory compliance and inter-operator coordination for a wellbore traversing adjacent units, mitigating conflict risk.	2026-02-11	General Oilfield Services

💡 Operator Intent

Execute a multi-well pad development with precise anti-collision management, targeting the Middle Bakken from an off-lease surface location.

Well is part of a pad with multiple Jaffa and Tunnock wells shown on location plats; anti-collision statement details real-time survey corrections, gamma ray signatures, and 1.2 separation factor; affidavit confirms surface use agreement for off-lease drilling.
Optimize completion cost and efficiency by employing a 'wet shoe' liner design to enable cheaper wireline pump-down toe initiation instead of tubing-conveyed perforating.

Detailed wet shoe schematic and description specify intentional 400 ft uncemented annulus and over-displacement to allow wireline pump-down of first stage guns, stating it avoids 'more expensive option of perforating on tubing or with a tractor.'
Adhere to a strict environmental and regulatory compliance posture, particularly regarding fluid systems and waste disposal.

Explicit prohibition of diesel-based stimulation compounds, commitment to use licensed drill cuttings disposal facilities, and assertion of filter sock container compliance from spud through flowback.

🔧 Service Operator Relevance

Directional Drilling & Surveying

Anti-collision plan requires real-time corrected surveys, gamma ray correlation, and close approach monitoring with many offset wells. High-precision steering and survey services are critical for safe drilling given dense wellbore environment.

Cementing & Cased Hole Logging

Non-routine CBL requirements on intermediate string and wet shoe design demand precise cement job execution and evaluation. Additional logging runs create service opportunities pre- and post-cementing.

Stimulation & Completion Fluids

Operator's prohibition of diesel-based compounds mandates alternative fluid systems for fracturing. Chemical suppliers must provide compliant formulations.

Waste & Solids Disposal

Operator commits to using a licensed disposal facility for drill cuttings, listing several specific vendors. Hauling and disposal contracts will be awarded to one of these pre-vetted facilities.

Pad Construction & Earthwork

Permit requires contact with NDIC inspector prior to construction. Detailed earthwork quantities and pad design indicate imminent grading and construction activity in preparation for July 2025 spud.
