📊 Signals (7)

Tier	Signal	Date	Service Impact
Tier 3	Surface casing depth revised from 3000' to 2400' via Sundry Notice (Request for Consideration/Waiver). 📄 SUNDRY FORM FOR WELL FILE NO.: 42386 DESCRIPTION (OPERATOR) Operator proactively changed well design after permit approval, indicating potential geohazard reassessment or cost optimization. This creates a specific, non-standard casing point for cementing and drilling services.	2026-07-20	Regulatory / Permitting
Tier 3	State Geologist requires sample collection 'no lower than the: Base of the Last Charles Salt' at specific intervals, with 30-day submission deadline post-drilling. 📄 RE: CORES AND SAMPLES letter Imposes a specific, non-routine sampling protocol tied to a geologic marker (Base of Last Charles Salt) with strict packaging and timing requirements. Violations carry significant fines.	2025-10-13	Mud / Fluids
Tier 3	Permit includes explicit prohibition: 'Eben Operating may not use MTN Poly in the surface mud program.' 📄 PERMIT INFORMATION STIPULATIONS Regulatory mandate banning a specific product (MTN Poly, a viscosifier) in the surface hole. This is a non-standard, operator-specific restriction not found in generic permits.	2025-10-09	Mud / Fluids
Tier 3	Forest Service Private Road Special Use Permit issued for access road, expiring 12/31/2044. 📄 U.S. DEPARTMENT OF AGRICULTURE FOREST SERVICE PRIVATE ROAD SPECIAL USE PERMIT Well access requires a long-term (19-year) Forest Service permit with specific construction/maintenance stipulations. This is a non-routine surface access complexity.	2025-06-24	General Oilfield Services
Tier 3	Heater-Treater vendor pre-selected: 'Manufacturer: Dragon out of Casper Wyoming'. 📄 PROPOSED WORK section Operator has already specified a niche equipment vendor (Dragon), indicating a preferred supplier relationship for production equipment.	Unknown	General Oilfield Services
Tier 3	Drilling program states 'SPUD DATE: AFTER SEPTEMBER 16' (year inferred as 2025 from context).⏰ TIME-SENSITIVE 📄 DRILLING PROGRAM (Version: Aug 1, 2025) Operator has defined a firm start window ('AFTER SEPTEMBER 16'), indicating planned mobilization timing. This is more specific than a generic permit date.	Relative	General Oilfield Services
Tier 3	Cuttings/fluid disposal site pre-selected: 'Rough Rider Disposal (15 miles south of Crested Butte)' and 'Produced water will go to Compass SWD.' 📄 MUD PROGRAM and PRODUCED WATER sections Operator has designated specific, named disposal facilities for both solids (Rough Rider Disposal) and liquids (Compass SWD). This locks in waste logistics.	Unknown	General Oilfield Services

💡 Operator Intent

Aggressive exploration of deep, high-pressure Duperow/Birdbear formations with contingency for H2S.

PTD 11,800', max BHP 4900 psi, max BHT 230°F, explicit note that 'H2S is a known possibility in the Mission Canyon formation.' Plan includes 1-2 DSTs and extensive logging.
Utilize a complex, multi-vendor operational model with clear division of responsibilities.

Drilling program lists separate contacts for Operator (Eben), Drilling Engineer (Tarpon Unlimited), President (RBR Oil & Gas), and Chief Geologist (Genuine Resource Group). Vendor proposals (cementing, mud) are from different specialized firms.
Prioritize regulatory compliance and surface owner relations due to US Forest Service land.

Secured a long-term Forest Service road permit. Drilling program includes extensive safety/environmental stipulations (fire retardant clothing, no static fabrics, closed mud system, filter sock container).

🔧 Service Operator Relevance

Cementing

Surface casing depth changed to 2400' (from 3000'). American Cementing's proposal must be revised. Job is pending spud after Sept 16, 2025.

Drilling Fluids / Mud Engineering

Permit explicitly bans MTN Poly in surface mud. Mountain Mud must reformulate. High-pressure, high-temperature well requires careful mud program management for salt sections and lost circulation.

Waste Hauling & Disposal

Operator pre-selected Rough Rider Disposal for cuttings and Compass SWD for produced water. Hauling contracts to these specific facilities need to be secured ahead of spud.

Well Testing (DST)

Northstar is preferred vendor for 1-2 DSTs. Planning and scheduling needed for tests in Duperow and potentially Madison intervals.

Logging & Sample Management

Mandatory sample collection protocol from Base of Last Charles Salt with 30-day shipping deadline. Mudlogger required at 8000'. Logging suite is extensive (Neutron/Density, GR/AIT, FES).
