📊 Signals

Tier	Signal	Date	Service Impact
Tier 2	Operator employs 'wet shoe' configuration for production liner, involving intentional over-displacement of cement by 7 barrels to create uncemented annulus, enabling wireline pump-down of first stage perforating guns to avoid more expensive tubing or tractor methods. Full Well Details Rystedt 5892 31-28 4B and Details of Standard Wet Shoe Rystedt 5892 31-28 4B	Unknown	Completions / Frac
Tier 3	Surface Use Agreement executed with landowner for drilling into off-lease units, affirmed by affidavit dated November 5, 2025. AFFIDAVIT AFFIRMING SURFACE USE AGREEMENT	2025-11-05	General Oilfield Services
Tier 3	Anti-collision report shows minimum separation factors as low as 0.322 (Level 3 warning) with EXIST HZ OVERAL 5892 11-30T, indicating close proximity drilling. Anticollision Report Summary	2025-10-21	Directional Drilling
Tier 3	Facility uses indirect heater with NDIC exemption (Case No. 28949 Order No. 31500), set within 60 feet of wellhead and 21 feet of oil tank, with impermeable dikes for containment. FACILITY STATEMENT	Unknown	General Oilfield Services

Tier 3	Pad construction uses existing on-site materials for earthwork, with scoria sourced privately for road surfacing, and dikes constructed of impermeable material with layer-by-layer compaction. NEW WELL PAD CONSTRUCTION STATEMENT	Unknown	General Oilfield Services

🎯 Operator Intent

Cost-optimize completions by using wet shoe for wireline perforating instead of more expensive methods.

↳ Document details intentional over-displacement to enable pump-down on wireline, avoiding tubing or tractor.
Minimize environmental and regulatory risks by avoiding diesel-based fracs and ensuring leakproof filter containers.

↳ Explicit prohibition on diesel CAS numbers and requirement for on-site filter storage with waiver option.
Aggressively space wells in mature areas despite anti-collision warnings, prioritizing density over safety margins.

↳ Anti-collision report shows Level 3 warnings and low separation factors near existing wells.
Expand drilling footprint efficiently by securing surface use agreements for off-lease units.

↳ Affidavit confirms SUA with landowner, allowing drilling outside primary spacing unit.

🔧 Service Relevance

Wireline and perforating services

Wet shoe configuration enables wireline pump-down of guns; immediate opportunity post-cementing for first stage initiation.

Anti-collision and surveying services

Frequent surveys (93-100 ft) and gamma ray correlation required during drilling; urgency in lateral sections near crossings.

Waste disposal and hauling

Cuttings disposal to closest licensed facility post-drilling; timing tied to completion of operations.

Core and sample analysis labs

Samples shipped within 30 days, cores within 180 days of drilling completion; window for geological services.
