📊 Signals (5)

Tier	Signal	Date	Service Impact
Tier 2	Wet shoe configuration on 4-1/2" liner with intentional over-displacement of cement by 7 barrels, creating ~400' uncemented annulus for economic toe initiation via pump-down perforating guns. 📄 Attachment 6 in Section 10, Wet Shoe discussion and Fig. 1.1 Non-standard liner cementing to enable cost-saving perforating method, deviating from typical full cement isolation.	Unknown	Completions / Frac
Tier 3	Waiver requested for notification to adjacent operator under Order No. 31848, as Oasis is the operator of the adjacent spacing unit. 📄 Letter dated February 19th, 2026, RE: Rosencrans wells Self-waiver due to operator control over adjacent unit, simplifying regulatory process in multi-well pad scenario.	2026-02-19	Regulatory / Permitting
Tier 3	Anticipated drilling commencement on June 7, 2025, with completion approximately 30 days thereafter.⏰ TIME-SENSITIVE 📄 Anticipated Starting Dates in Attachment 6 Specific timeline for operations in a future-dated permit, providing early visibility into activity window.	2025-06-07	Drilling Rigs
Tier 3	Closed mud system with no cuttings pit, and cuttings disposal to licensed facilities including Chimney Butte Environmental LLC, Dishon Disposal Inc., etc. 📄 New Pad Construction Statement and Licensed Facilities list in Attachment 6 Mandated environmental compliance choice in a new pad, specifying disposal vendors and closed-loop mud handling.	Unknown	Mud / Fluids
Tier 3	Anti-collision measures include AC guidance reporting, real-time corrected surveys, 1.2 separation safety factor, gamma ray signatures for wellbore identification, and surveys every 93'-100' in lateral. 📄 Anti-Collision Statement in Attachment 6 Detailed, proactive anti-collision protocol beyond standard NDIC requirements, indicating high-risk awareness in dense pad development.	Unknown	Directional Drilling

💡 Operator Intent

To optimize completion costs by using wet shoe for pump-down perforating instead of more expensive tubing or tractor methods.

Wet shoe configuration details in attachment, noting economic method for toe initiation.
To mitigate collision risks in a multi-well pad environment through advanced surveying and gamma ray identification.

Anti-collision statement specifying AC guidance, real-time surveys, and gamma ray signatures.
To expedite regulatory approval and operations by leveraging self-control over adjacent spacing unit.

Waiver request for adjacent operator notification due to same operator status.
