Identifier Usage Examples of Unique Well

Initial completion retains the originally assigned identifier with the zero event sequence, e.g., 00 06-12-045-12W4 0. Subsequent completions are assigned the next event sequence, e.g., 00 06-12-045-12W4 2. Event sequence codes are assigned chronologically. However, if both zones are completed in the same operation, the lower zone is deemed to be completed first. 2. Deepening of an existing well to a new geological horizon Existing well A-B has identifier of 00 06-14-045-12W4 0. Deepened...

Operation Type Codes

Holes are placed through the casing and cement and into the formation using a perforating gun, or the casing and cement are cut using sand-laden fluids to expose a formation. A method of completion common for a horizontal well. An open hole barefoot completion allows reservoir fluids to flow unrestricted no casing into the wellbore. This is a common completion for a horizontal well. A volume of acid is circulated down the wellbore over or into a completed interval. Chemicals are injected into...

How to Use This Guide Overview of the Guide

Section 12.010 of the Oil and Gas Conservation Regulations requires the licensee or a representative of the licensee to keep and file records and reports of daily operations on wells that are in the process of being drilled, completed, reconditioned, or abandoned in accordance with the current edition of this guide, Guide 59 Well Drilling and Completion Data Filing Requirements. A copy of these records must be submitted directly to the Alberta Energy and Utilities Board EUB Core Research Centre...

Plug Backs Abandonment Purpose Code

A cement plug or series of cement plugs is run in the hole for the purpose of abandonment. A cement plug is run before or after a casing has been set in the hole. A cement plug is run and is used to achieve the angle for directional or horizontal drilling from the original wellbore. A portion of the drill string or tools fish is stuck downhole and cannot be recovered. A cement plug is run over the fish, and a new hole is drilled around the fish to resume drilling operations. Drilling operations...

Drilling

Enter the drilling contractor's assigned four-digit Business Associate BA code. Enter the drilling rig number assigned to the contractor. Enter the date on which drilling of the well begins. Drilling to set conductor casing is not considered spud unless it is conducted by the drilling rig that continues to drill the remainder of the well. Drilling surface hole and setting of surface casing by a surface hole rig constitutes spud of a well. In cases of a newly licensed re-entry of a previously...
