📊 Signals (7)

Tier	Signal	Date	Service Impact
Tier 2	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 Specific geosteering and completion constraints imposed by Commission Order 35418, requiring precise wellbore placement and a 'wet shoe' completion design to manage boundary setbacks.	Unknown	Directional Drilling
Tier 2	Detailed 'Wet Shoe' completion configuration described: 400 ft of uncemented annulus at liner toe, over-displaced by 7 barrels to enable wireline pump-down of first stage guns, avoiding more expensive tubing/tractor methods. 📄 Wet Shoe section, page 10 Explicit, non-standard completion design aimed at cost reduction for toe initiation. Reveals specific operational sequence and fluid displacement volumes.	Unknown	Completions / Frac
Tier 3	Affidavit affirms Surface Use Agreement executed with landowner for off-lease drilling, and drill-back notification provided to adjacent operator (Silver Hill Energy) via email on 6/25/2026. 📄 AFFIDAVIT sections, end of document Confirms all surface and offset operator notifications are complete as of a specific recent date, clearing a major pre-drilling regulatory hurdle.	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 8 Specific planned spud date and duration provided in the well plan attachment, indicating operator's forward schedule.	2025-06-07	Drilling Rigs
Tier 3	Facility design uses an indirect heater with a setback exemption (NDIC Case No. 28949 Order No. 31500), allowing placement within 60 ft of wellhead and 21 ft of oil tank. 📄 FACILITY STATEMENT section, page 10 Non-standard facility layout enabled by a pre-existing regulatory variance. This pre-selected equipment choice impacts pad footprint and piping.	Unknown	General Oilfield Services
Tier 3	Operator must contact NDIC Field Inspector Jason Hicks prior to location construction.⏰ TIME-SENSITIVE 📄 Stipulations section, page 1 Mandatory pre-construction field inspection contact, specifying the individual inspector (Jason Hicks).	Relative	General Oilfield Services
Tier 3	Operator asserts they have previously permitted wells on this unit and have submitted sundries to cancel those permits, which are pending approval. 📄 PROPOSED WORK section, page 6 Reveals a change in well plan or pad layout, with regulatory paperwork (sundry notices) in flux. Indicates potential for last-minute adjustments or delays if cancellations are not finalized.	Unknown	General Oilfield Services

💡 Operator Intent

To drill multiple wells from a single pad location outside the target spacing unit ('off-lease') to efficiently develop the unit.

Affidavit states Oasis will operate Isabella 5993 14-1 2BX, 3B, and 4BX from this location, drilling into 'off-lease' units. The pad layout sheets show multiple wellheads.
To optimize completion cost by employing a 'Wet Shoe' design to enable cheaper wireline pump-down perforating for the first stage.

Explicit description of wet shoe configuration states it '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 utilize a pre-approved, non-standard facility layout to minimize pad footprint.

Facility Statement specifies use of an indirect heater with a specific setback exemption (Case No. 28949), allowing tighter clustering of equipment.

🔧 Service Operator Relevance

Pad Construction & Earthwork

Operator must contact Inspector Jason Hicks prior to construction. Anticipated spud date is June 2025, so pad build likely needs to commence weeks/months prior. Detailed earthwork quantities (78,100 CY) and designs are provided.

Directional Drilling & Surveying

Strict stipulations on wellbore placement within corridor and setbacks. Anti-collision statement shows proximity to many existing wells, requiring precise navigation. Detailed survey program and anti-collision report included.

Cementing & Completions

Non-standard 'Wet Shoe' liner cementing design with specific over-displacement volume required. Surface casing cementing has specific centralizer placement rules. Must 'frac out the shoe' as per stipulation.

Drilling Waste Disposal

Document lists nine specific licensed disposal facilities for dry cuttings, with Whiting indicated as the handler. This defines the approved vendor ecosystem for waste hauling.
