Directive 020: Well Abandonment
Purpose of this Directive
This directive sets out the minimum requirements for abandonments, casing removal, zonal abandonments, and plug backs as required under section 3.013 of the Oil and Gas Conservation Rules. The objective of a well abandonment is to cover all nonsaline groundwater (water with total dissolved solids less than 4000 milligrams per litre) and to isolate or cover all porous zones. All open-hole and cased-hole abandonments must be conducted in accordance with the requirements in this directive.
Note: Well status (set through Petrinex) and licence status (set through the Digital Data Submission system) should align. For a list of valid combinations, refer to the well/licence status matrix linked below.
