📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 2	Approval conditional on 'wet shoe' completion design with cemented production liner in lateral to enable frac out of shoe, allowing 150' north/south setbacks vs. standard 500'. 📄 Page 1, Stipulations section Specific engineering design mandated by regulator to achieve tighter spacing, indicating a tailored completion strategy that deviates from standard casing/cementing.	Unknown	Completions / Frac
Tier 3	Anticipated commencement date is June 7, 2025, with drilling days approximately 30.⏰ TIME-SENSITIVE 📄 Attachment section, 1.8 Anticipated Starting Dates Specific planned spud date provided in attachment, indicating near-term operational timeline.	2025-06-07	General Oilfield Services
Tier 3	Facility design uses an indirect heater with a setback exemption (Case No. 28949 Order No. 31500), allowing placement within 60' of wellhead and 21' of oil tank. 📄 Attachment section, FACILITY STATEMENT Non-standard regulatory variance for equipment placement, indicating pre-approved, compact facility design.	Unknown	General Oilfield Services
Tier 3	Operator must contact NDIC Field Inspector Jason Hicks (701-720-3523) prior to location construction. 📄 Page 1, Permit Review Policy Explicit, named regulatory point of contact required before pad construction begins, indicating heightened oversight or site-specific conditions.	Relative	General Oilfield Services
Tier 3	Operator has submitted sundries to cancel previously permitted wells on this unit, which are pending approval. 📄 Page 6, PROPOSED WORK section Indicates active permit portfolio management, replacing older plans with this new well design, showing persistent intent to develop the unit.	Unknown	General Oilfield Services

💡 Operator Intent

To drill multiple wells ('Isabella 5993 14-1 2BX, 3B, 4BX') from a single pad located outside the target spacing unit, requiring a Surface Use Agreement and drill-back notifications.

Affidavit affirming SUA and drill-back notification, plus pad layout showing multiple well paths. 'We have previously permitted wells on this unit... submitted sundries to cancel those permits.'
To utilize a 'wet shoe' liner configuration to enable cost-effective toe initiation (wireline vs. tubing/tractor) and achieve regulatory approval for reduced boundary setbacks.

Stipulation notes north setback based on 'production liner cemented in the lateral with a wet shoe and the ability to frac out the shoe.' Detailed wet shoe diagram and explanation in attachment.
To implement a robust anti-collision strategy using real-time corrected surveys, gamma ray signatures, and increased survey frequency near existing wellbores.

Anti-collision statement details specific procedures: 'real-time corrected surveys,' '1.2 separation safety factor,' 'Gamma ray signatures to identify... existing wellbores,' and increased survey frequency 'when approaching lateral crossings.'

🔧 Service Operator Relevance

Drilling & Directional Services

Specific spud date (June 7, 2025) and ~30-day drilling window. Anti-collision procedures mandate precise surveying (every 93'-100', increasing near crossings), requiring advanced MWD/geosteering capabilities.

Cementing & Completion Services

Non-standard 'wet shoe' liner design requires precise cement over-displacement (7 bbls) to create 400' uncemented annulus. This design is critical for permitting and dictates specific cementing, perforating, and toe initiation services.

Waste Management / Solids Disposal

Operator explicitly lists Whiting for cuttings disposal to 'closest available facility.' Requires leak-proof filter sock container on-site from spud through flowback. Regulatory focus on proper filter disposal creates ongoing service need.

Facility Construction & Equipment

Pad construction requires contact with inspector Jason Hicks before start. Facility design uses a specific indirect heater with a setback exemption, indicating need for that equipment type and compact layout installation.
