💡 Operator Intent

Pursue efficient and responsible horizontal drilling in Bakken with emphasis on regulatory compliance and advanced completion techniques.

Multiple stipulations on setbacks, cementing, logging, and assertions on notifications and safety, combined with wet shoe design for frac-out.

Minimize environmental impact near occupied dwellings through controlled facility placement and operations.

Assertions on dwelling proximity, spill plans, and conditions on flares/tanks location.

🔧 Service Operator Relevance

Mud logging and cement bond logging services

Mandatory requirements effective immediately upon spud, with approval dated 02/06/2026, creating immediate opportunity for specialized logging contractors in surface and intermediate casings.

Indirect heating equipment supply

Specified use of Steffes or JW Williams heaters for facilities, timed with potential operations start post-approval, allowing vendors to prepare inventory for winter drilling.
