When a slotted liner is run in a horizontal well, in addition to reporting it in the casing record, you must also report it in the completion record showing the interval of the well covered by the slotted liner from the shoe set depth of the previous casing to the shoe set depth of the liner . If the slotted liner is not run all the way to total depth, the open hole interval must also be recorded from the shoe set depth of the liner to total depth. If after running casing, the casing shoe is...

When a well is in the process of being drilled, completed, reconditioned, or abandoned, the licensee or its representative must keep at the well or the field office a daily record of operations performed. The daily report must set out complete data on all operations carried on during the day for drilling, fishing, shooting, perforating, acidizing, fracturing, surveying, testing, and abandonment operations. The information that the daily report must contain is outlined in Appendix 3 of this...
Drilling Operations
Re-entry operations An abandoned well licensed to another company is re-entered by a different company. An application for a well licence is required to be filed and approved by the Applications Branch see Guide 56 Energy Development Application Guide before the re-entry operations begin. If the abandoned well belongs to the same company that is re-entering, it has to apply for an approval to resume drilling. The status of the original well will be changed to Abandoned and Re-entered by the...
Plug Back
Only record plugs that are left in the well at the end of the operation. Do not record cement plugs that are run in a leg of a well not considered a drilling event e.g., a ghost hole . See Appendix 1. You may use a 3 m high-density cement plug if the plug length is an operational issue. If the plug is less than 3 m, you must get preapproval from the EUB Operations Group. Plug-Back Date Plug-Back Purpose Code Enter the dates that the plug was run in chronological order. Enter the code from Table...
