📊 Signals (6)

Tier	Signal	Date	Service Impact
Tier 2	Approval conditional on 150' north and 500' west setbacks within the Alger-Bakken Unit, with north setback based on a production liner cemented in the lateral with a wet shoe and the 'ability to frac out the shoe'. 📄 STIPULATIONS, NDIC Field Order Info Explicitly ties regulatory approval to a specific, non-standard completion technique (frac'ing out a wet shoe). This is a design-driven regulatory condition, not a generic setback rule.	2026-07-28	Completions / Frac
Tier 3	Anticipated drilling start date provided in waiver request as 11/15/2026, with operation duration 60-90 days.⏰ TIME-SENSITIVE 📄 Waiver Request letter dated April 15, 2026; Drilling Plan Provides a specific, forward-looking timeline for drilling operations, which is not routine permit data. Shows operator planning and intent.	2026-11-15	Drilling Rigs
Tier 3	Waiver granted for open hole logs, relying on offset well data within one mile (Cottonwood 5-34H, File #17937). Only GR-CBL will be run from TD to surface. 📄 SUNDRY FORM FOR WELL FILE NO.: 43161, DESCRIPTION (OPERATOR) Indicates a deliberate cost and time-saving operational choice, deviating from standard logging requirements. Signals confidence in existing subsurface data and reduces vendor opportunity for open-hole logging services.	2026-07-30	Regulatory / Permitting
Tier 3	Operator submitted a waiver request for NDIC Orders 31848 and 31973 (regarding notification for wellbores entering adjacent units) because EOG is the operator of all adjacent spacing units. 📄 Waiver Request letter dated April 15, 2026 Demonstrates EOG's consolidated leasehold position in the area, allowing them to bypass inter-operator notification rules. Shows strategic acreage block development.	2026-04-15	Regulatory / Permitting
Tier 3	Operator must contact NDIC Field Inspector Marc Binns (701-770-2564) prior to location construction. A specific inspector is named for pre-spud notification.⏰ TIME-SENSITIVE 📄 STIPULATIONS, Construction Commencement Notification Reveals a personalized regulatory touchpoint and a required action before pad construction can begin. Indicates heightened oversight or specific local conditions.	Relative	General Oilfield Services
Tier 3	Facility equipment (e.g., production) is located on a separate, off-lease tract (Ross 5 NWNW - CTB, Lot 4, Sec 5). Requires an attached facility diagram and off-lease affidavit. 📄 PROPOSED WORK Indicates a centralized production facility strategy, with infrastructure not co-located on the drill pad. Requires additional surface agreements and planning.	Unknown	General Oilfield Services

💡 Operator Intent

To develop a multi-well pad (Ross 6 NENW) with centralized production facilities, maximizing efficiency on a consolidated leasehold.

Well file includes plats for pad 'ROSS 6 NENW' showing multiple well sites (Cottonwood 14-3321H, 101-3321H, 16-3321H, Ross 56-0616H, 114-0616H). Facility equipment is designated for a separate Central Tank Battery (Ross 5 NWNW - CTB), and affidavits cover multiple wells jointly.
To optimize well costs by reducing data acquisition where existing data is deemed sufficient.

Successful waiver request to forego open hole logs, relying on offset well data. This reduces logging costs and rig time.
To employ an aggressive completion design that includes fracturing out the liner shoe to manage boundary setbacks.

Regulatory approval is explicitly conditioned on the 'ability to frac out the shoe' of the production liner to meet the north boundary setback, indicating this is a planned component of the completion.

🔧 Service Operator Relevance

Pad Construction & Earthworks

Specific pre-construction notification required to NDIC Inspector Marc Binns. Pad design by KLJ includes significant cut/fill volumes (27,990 CY cut, 19,090 CY fill) and a perimeter moat, indicating imminent earthmoving scope.

Cementing Services

Halliburton is explicitly named for surface casing cement. Detailed cementing programs for intermediate and production liners indicate upcoming major cement jobs. The 'wet shoe' design for the production liner is a specific technical requirement.

Completion/Stimulation Services

The well plan includes '83 Proposed Stages' and regulatory approval is contingent on the 'ability to frac out the shoe.' This signals a major hydraulic fracturing operation is planned post-drilling, with a specific technical requirement for the toe initiation.

Directional Drilling & MWD Services

Complex well path with KOP at ~9458' MD and a long lateral (~16,579 ft). Detailed directional plan and survey requirements indicate need for precise directional drilling services. The waiver for open-hole logs increases reliance on MWD data.
