📊 Signals (7)

Tier	Signal	Date	Service Impact
Tier 1	Approval conditional on wellbore being located down north-south axis within 500' drilling corridor and no closer than 150' setback from north & south boundaries within 5120-acre spacing unit. North setback based on production liner cemented in lateral with wet shoe and ability to frac out the shoe. 📄 Stipulations section, page 1 Imposes specific directional and geometric constraints on well placement, affecting drilling and completion design. The 'wet shoe' configuration is explicitly tied to regulatory approval.	Unknown	Directional Drilling
Tier 2	Use of 'wet shoe' completion configuration: liner cement intentionally over-displaced by 7 barrels, creating ~400' of uncemented annulus at toe to allow pump-down of first stage perforating guns on wireline. 📄 Wet Shoe section, page 11 A specific, non-standard completion technique chosen to avoid more expensive perforating methods (tubing or tractor). This is a deliberate design choice affecting cementing and stimulation.	Unknown	Completions / Frac
Tier 3	Affidavit affirming Surface Use Agreement executed with landowner for off-lease drilling, dated June 30, 2026. 📄 AFFIDAVIT AFFIRMING SURFACE USE AGREEMENT, page 15 Surface agreement is finalized and documented for drilling from a location outside the target spacing unit. Shows advanced surface land work is complete, removing a key pre-construction hurdle.	2026-06-30	General Oilfield Services
Tier 3	Drill-back notification provided to adjacent operator (Silver Hill Energy) via email on 6/25/2026, as required for off-spacing drilling. 📄 AFFIDAVIT AFFIRMING DRILL-BACK NOTIFICATION, page 15 Demonstrates regulatory compliance and proactive communication with offset operator. Reveals the identity of the adjacent operator who was notified.	2026-06-25	General Oilfield Services
Tier 3	Anticipated Commencement Date: Jun 07, 2025. Drilling Days: Approximately 30 days.⏰ TIME-SENSITIVE 📄 Anticipated Starting Dates section, page 7 Provides a specific planned start date and duration for drilling operations, which is not standard in permit data.	2025-06-07	Directional Drilling
Tier 3	Operator must contact NDIC Field Inspector Jason Hicks prior to location construction.⏰ TIME-SENSITIVE 📄 Stipulations section, page 1 Mandatory pre-construction regulatory contact with a named individual. Indicates heightened oversight or specific site conditions requiring inspector awareness before work begins.	Relative	General Oilfield Services
Tier 3	Operator has submitted sundries to cancel previously permitted wells on this unit, which are pending approval. 📄 PROPOSED WORK section, page 6 Reveals a change in development plan for the unit. The operator is consolidating or altering its well program, canceling old permits in favor of this new pad/well design.	Unknown	General Oilfield Services

💡 Operator Intent

To develop the unit from a new, consolidated pad location, superseding previous individual well plans.

Document states 'We have previously permitted wells on this unit. We have submitted sundries to cancel those permits, which are pending approval.' Combined with the affidavit for a 3-well pad (2BX, 3B, 4BX).
To optimize completion cost and efficiency by employing a 'wet shoe' design to enable cheaper Stage 1 perforating.

Explicit description of wet shoe configuration 'allows the operator to pump-down the first stage perforating guns on wireline, avoiding the more expensive option of perforating on tubing or with a tractor.'
To proactively manage anti-collision risks in a densely drilled area using specific technologies and protocols.

Anti-collision statement details use of AC guidance reporting, real-time corrected surveys, industry standard 1.2 separation factor, gamma ray signatures for identification, and increased survey frequency near crossings.

🔧 Service Operator Relevance

Drilling & Directional Services

Specific start date (Jun 7, 2025) and ~30-day drilling window provided. Strict directional constraints (north-south axis, setbacks) and anti-collision protocols require precise execution.

Cementing

Non-standard 'wet shoe' liner cement job requiring intentional over-displacement. Specific centralizer program for surface casing. Cement top job required if fallback >10' below ground.

Completion & Stimulation

Wet shoe design dictates a wireline pump-down operation for Stage 1 perforating, affecting service selection. Frac design will be based on post-completion production rates.

Earthwork & Pad Construction

Mandatory contact with NDIC Inspector Jason Hicks required prior to construction. New pad construction with detailed earthwork quantities (78,100 CY excavation/embankment). Dikes and base must be impermeable.

Waste Hauling & Disposal

Operator has pre-identified a list of 8 licensed disposal facilities for dry cuttings. On-site leak-proof container for filter socks required from spud through flowback.

Surveying & Well Planning

Complex anti-collision environment with many offset wells. Survey frequency mandates (100' vertical, 30' curve, 90' lateral). Certified surveys must be submitted to NDIC email.
