💡 Operator Intent

To implement engineered casing wear mitigation and advanced evaluation techniques.

The waiver request details a refined drilling process to prevent top joint casing wear (extended wear bushing, rotating head, deeper directional start) and proposes replacing visual inspection with quantitative wireline caliper logs.

To drill a pad of wells with coordinated operations and shared infrastructure.

Multiple sundry notices reference the Shorthorn pad with six wells, shared sample collection, a unified gas capture plan with 1804 LTD, and a pad expansion for a larger rig serving all wells.

🔧 Service Operator Relevance

Wireline Logging (Casing Evaluation)

The approved waiver specifically mandates a wireline logging solution (caliper logs) for evaluating the top intermediate casing joint and surface equipment, creating a direct service requirement.

Directional Drilling / MWD Services

The approved survey frequency waiver indicates specific drilling pipe and survey practices. The well was just spudded, so directional services are actively needed.

Earthwork / Civil Construction

The pad expansion for a larger rig was approved in May 2026, indicating recent or pending grading, excavation, and construction work.

Waste Management / Solids & Liquids Disposal

The identified contractors IHD Solids and IHD Liquids Management are designated for cuttings and mud disposal from the drilling operation, which is currently active.
