Today, we released a new edition of Directive 020: Well Abandonment. The revised directive permits using AER-approved alternative materials as capping materials for routine non-level-A zonal abandonments using a permanent bridge plug or permanent packer with a permanent plug.
We revised sections 5.4.2, 5.4.4, and 5.4.5.2 and added appendix 2 to amend the materials requirements allowed for permanent bridge plugs or packers. Appendix 2 lists the AER-approved alternative materials and the corresponding specific criteria for their use.
We also included section 91 and 106 references to the Brine-Hosted Mineral Resource Development Rules in sections 1.1 and 6.1 of the directive.
The revised edition of the directive is available on the Directive 020 landing page. If you have any questions, contact our Customer Contact Centre by phone at 1-855-297-8311 or by email at inquiries@aer.ca.
