Regulatory / Permitting

💡 Operator Intent

Optimize completion efficiency with wet shoe design to enable pump-down of perforating guns without fracing out

Sundry request for completion method change, specifying wet shoe sub and no frac capability, allowing stage 1 gun placement

Minimize operational disruptions by obtaining waivers for on-site infrastructure like filter sock containers

Waiver request to limit container presence to drill-out phase only, citing reduced debris and cost savings

Achieve efficient lateral drilling in a single run within target dolomite

Geological summary notes lateral drilled in one run, staying within Middle Bakken Dolomite with consistent samples

🔧 Service Operator Relevance

Completion services with wet shoe and pump-down technology

Operator's recent waiver approval (July 2025) for wet shoe setup signals immediate opportunity for vendors providing specialized perforating and completion tools

Directional drilling and BHA optimization

Trip due to slow build rates in July 2025 indicates potential need for enhanced directional services to improve curve drilling efficiency

Gas monitoring and ROP management

High gas peaks (up to 6621 units) and variable ROP during lateral drilling (July-August 2025) suggest demand for real-time monitoring tools
