Operator requested Suspension of Drilling (SOD) for up to 90 days to drill surface hole with smaller rig (T&S Drilling Rig #2) and then move on larger rig (Nabors B21) within 90 days.โฐ TIME-SENSITIVE ๐ Sundry Form - Suspension of Drilling Two-rig strategy: small rig for surface hole (3-5 days), then larger rig for TD. Explicitly states intent to save cost and time. Requires immediate calls to NDIC after spud and when plug bumped. |

Operator requested and received waiver to run tubing and packer, planning to flow well up 7'' casing after frac completion. ๐ Sundry Form - Request for Consideration/Waiver (Tubing/Packer Waiver) Deviates from standard completion design by eliminating tubing and packer, indicating a cost-saving or operational efficiency intent. Uses casing as production conduit with specific safety factor and monitoring protocols. |

Well name changed from SEVERANCE 153-89-4-9H-2 to SHELL 153-89-5-16H-1, and spacing unit expanded from 1280-acre to 3840-acre. ๐ Sundry Form - Well Information / Well Name Change and Permit Modification sections Significant redesign: well name change, lateral extension from ~10,000 ft to ~15,400 ft (based on bottom hole location change), and spacing unit tripled in size. Indicates a major revision in development plan. |
