| Tier 3 |
Operator requested and received waiver to run tubing and packer, planning to flow up 7" casing after frac completion. ๐ WELL SUNDRY FORM - Request for Consideration/Waiver Non-standard completion design indicates intent to accelerate production and reduce costs by eliminating tubing string installation initially. Shows operator confidence in casing integrity and flowback monitoring. |

| Tier 3 |
Lateral section experienced lost circulation issues affecting curve landing, requiring short-landing into Middle Bakken. ๐ GEOLOGIC SUMMARY Lost circulation forced operational compromise on landing point. Indicates challenging pressure regimes in target zone. |

| Tier 3 |
Original wellbore had surface casing shoe track break off and required sidetrack after multiple cement plugs and junk isolation. ๐ GEOLOGIC SUMMARY Significant drilling problem requiring sidetrack, multiple cement plugs, and operational delays. Indicates potential casing wear or mechanical issues in offset wells. |
2025-10-31 | Drilling Rigs |
| Tier 3 |
Operator used two-rig strategy: small rig (T&S Drilling Rig #2) for surface hole, then larger rig (NABORS B21) within 90 days for main drilling. ๐ WELL SUNDRY FORM - Suspension of Drilling Cost-saving approach using smaller rig for surface section with specific regulatory approval (SOD). Shows planned rig sequencing and pad optimization. |

| Tier 3 |
Open hole log waiver granted based on offset well Lee 8-5H 1 within one mile, with only GR-CBL planned from TD to surface. ๐ WELL SUNDRY FORM - Open Hole Log Waiver Regulatory exception reduces logging costs and time. Indicates operator reliance on existing subsurface data from offset. |
2025-06-10 | Mud / Fluids |
| Tier 3 |
State required specific sample collection protocol: 30' intervals in vertical/build sections, 200' in lateral, with submission deadline 30 days after drilling completion.โฐ TIME-SENSITIVE ๐ CORES AND SAMPLES letter Regulatory mandate with strict timing for sample submission. Non-compliance carries significant penalties. |
