Regulatory / Permitting

💡 Operator Intent

Minimize operational costs through regulatory waivers and non-standard completion techniques.

Waiver for open hole logs citing offset data and use of wet shoe liner configuration for wireline perforating.

Ensure precise and safe drilling with advanced monitoring and geosteering.

Early start of geological services, remote geosteering, H2S monitoring, and anti-collision precautions using gamma ray signatures.

Comply with regulatory timelines to expedite project execution.

Timely Sundry filing for spud notification and waiver request submission.

🔧 Service Operator Relevance

Geosteering and directional drilling services

Geological services activated early on October 24, 2025, providing immediate opportunity for vendors like Core Geologic and Badger to support ongoing operations.

Mud and chemical services

OBM system from surface to curve, with Mountain Mud as supplier, signals ongoing need for fluid management during drilling phase ending October 30, 2025.

Regulatory and permitting support

Waiver approved May 20, 2025, but drilling commenced September 2025, indicating past opportunity for consultants in waiver justifications using offset data.
