Waiver request to run tubing and packer, allowing flow up 7" casing post-frac ๐ WELL SUNDRY FORM - Request for Consideration/Waiver Operator seeks regulatory exception to standard completion design, indicating a deliberate choice to flow up casing rather than tubing. This suggests a focus on cost reduction or operational simplicity, but introduces casing integrity risks during flowback. |

Observation of decreased gas shows due to reservoir depletion compared to previous local wells ๐ GEOLOGIC SUMMARY Geologist notes reservoir depletion signal, stating production will heavily depend on rock permeability and induced fractures. This suggests the area may require more aggressive stimulation or enhanced recovery methods. |

Curve section short-landed at 9,382' MD due to lost circulation, forcing intermediate casing placement near top of Middle Bakken ๐ GEOLOGIC SUMMARY Drilling problem forced deviation from plan. Lost circulation restricted landing of curve BHA, leading to casing set higher than intended. This may impact subsequent lateral placement and completion effectiveness. |

Suspension of Drilling (SOD) request for up to 90 days to use smaller rig for surface hole, then move off and bring larger rig laterโฐ TIME-SENSITIVE ๐ WELL SUNDRY FORM - Suspension of Drilling Non-routine staged drilling approach to achieve cost/time savings. Explicitly states intent to spud with T&S Drilling Rig #2, then move off for 3-5 days, and bring Nabors B21 rig on around 2025-11-03. This creates two distinct rig mobilization/demobilization events. |

Open hole log waiver granted based on offset well data ๐ WELL SUNDRY FORM - Open Hole Log Waiver Operator successfully avoided running full open hole logs, relying on offset Lee 8-5H-1 data. Only GR-CBL from TD to surface required. This reduces logging costs and time but increases reliance on offset data accuracy. |

State mandate for specific sample collection protocol starting at Base of Last Charles Salt ๐ NORTH DAKOTA MINERAL RESOURCES letter Regulatory requirement with precise depth triggers (30' intervals in vertical/build, 200' in lateral) and 30-day submission deadline post-drilling. Non-compliance carries civil penalties up to $12,500 per offense. |
