Directional Drilling

💡 Operator Intent

To drill a long lateral well with a specific 'wet shoe' completion design to enable cost-effective toe initiation.

The 'wet shoe' configuration involves a standard cemented liner, whereby the cement job is intentionally over-displaced by 7 barrels of displacement fluid, creating approximately 400' of uncemented annulus around the toe-portion of the liner.

To manage high anti-collision risk in a dense well environment using specific procedures and technology.

Operator maintains an industry standard 1.2 separation safety factor while drilling the intermediate sections. Operator utilizes Gamma ray signatures to identify the location of the existing wellbores in target zone.

To expedite drilling by requesting a waiver from the mandatory notification to adjacent operators, citing common ownership.

Oasis Petroleum North America, LLC is the operator of the adjacent spacing unit, therefore a waiver on said notification is requested.

🔧 Service Operator Relevance

Directional Drilling / Surveying / Anti-Collision Services

The anti-collision statement and detailed plan indicate high risk in a dense well environment, requiring sophisticated real-time monitoring and survey services. The plan is approved and drilling is imminent (Anticipated Commencement Date: Jun 07, 2025).

Cementing & Completion Services

The explicit 'wet shoe' design requires precise cement over-displacement and creates a specific completion operation for toe initiation. This is a non-standard procedure tied to the approved well design.

Drill Cuttings Disposal

Operator has pre-selected a list of licensed disposal facilities, indicating hauling and disposal contracts will be awarded based on proximity. The list is current and part of the permit.

Pad Construction & Earthwork

The permit includes detailed construction plans, earthwork quantities, and a new pad construction statement. The mandatory inspector contact must occur prior to construction, indicating imminent ground-breaking.
