New Edition of Directive 065: Resources Applications for Oil and Gas Reservoirs Released

Apr 09, 2014

This bulletin announces the release of a revised edition of Directive 065, effective April 9, 2014, which incorporates all of the proposed changes announced in Bulletin 2012-26: Invitation for Feedback on Draft Revision of Directive 065: Resources Applications for Oil and Gas Reservoirs.

During the feedback period on the draft directive from December 20, 2012, to February 15, 2013, the Alberta Energy Regulator (AER) received submissions from six companies, as well as one from the Canadian Association of Petroleum Producers. A summary of the stakeholders’ submissions and the AER’s responses is available from the directive’s webpage on the AER website,

The feedback was used to clarify certain aspects of the directive and to compile a list of frequently asked questions (FAQ). The FAQ document is also available from the directive’s webpage.

The key changes to Directive 065 are as follows:

  • Informational Letter (IL) 92-5: Reduced Fluid Sampling and Analysis for Hydrocarbon Miscible Flood Schemes and IL 96-2: Progress Report Requirements for Miscible Flood Schemes have been summarised in the directive and have now been rescinded.

Units 2 and 4

  • Requirements for assessing and assigning MWHIP have been added.
  • The applicant must notify the licensees of abandoned wells in the vicinity of planned injection operations.

Unit 4

  • The need to confirm nonobjection has been removed from the stakeholder notification requirements for Class I fluid disposal. This is consistent with the notification requirements for other fluid classes, as per table 1 of the Resources Applications Notification Guidelines in Directive 065.
  • A new requirement has been added for all disposal schemes into hydrocarbon-bearing pools or their associated aquifers with respect to maximum operating reservoir pressure and the method of pressure monitoring.

Unit 5

Appendix E
  • AER Staff Contacts has been removed and replaced in the main body of the directive with the contact details for the Resources Applications help line.
Appendix O
  • This is a new appendix that has been added that sets out the procedure for a step-rate injectivity test to determine MWHIP.

This bulletin also announces that effective immediately, all enhanced recovery approval documents will contain the approved MWHIP for each well listed on the document. 

The new edition of Directive 065 is available on the AER website, Printed copies of the directive may be purchased from the AER Information Management Branch, 10 Floor, 250 – 5 Street SW, Calgary, Alberta; telephone: 403-297-8311 or 1-855-297-8311 (toll free); fax: 403-297-7040; e-mail:

The AER will be hosting information sessions on the revisions to Directive 065 for industry personnel who regularly file subsurface applications. The session details will be announced shortly on the AER website.
