🎯 Operator Intent

Optimize well spacing and density within spacing unit by adopting wet shoe completion to reduce boundary setbacks

↳ Sundry approval for 100' south setback based on cemented liner with no frac capability, as detailed in permit stipulations and directional plans

Minimize operational costs through regulatory waivers for logging and waste management

↳ Approved waivers for open hole logs using offset data and filter sock container during non-filtration phases

Achieve efficient lateral drilling with high ROP and gas detection in target window

↳ Average ROP 349 ft/hr, 96% in target window, peak gas 7,875 units, with sidetracks to maintain trajectory

🔧 Service Relevance

Completion Services (wet shoe liner cementing)

Well awaiting completion post-TD on September 14, 2025, with approved design change in July 2025, creating immediate opportunity for cementing contractors specializing in non-frac laterals

Directional and MWD Services

Sidetracks performed in September 2025 indicate ongoing need for precise steering in Middle Bakken, with vendors like Taktikal and Badger already engaged
