Invitation for Feedback - Revisions to Directive 051: Wellbore Injection Requirements
The Energy Resources Conservation Board (ERCB) is requesting stakeholder feedback on revisions to Directive 051: Wellbore Injection Requirements.
In 1994, the ERCB released Directive 051: Injection and Disposal Wells—Well Classifications, Completions, Logging, and Testing Requirements, which set out requirements for wellbore design, wellbore integrity logging, operational monitoring, and reporting requirements of injection wells for the purposes of enhanced recovery, hydrocarbon storage, and disposal.
Since 1994, the number of wells used for enhanced recovery and disposal has increased significantly. Also, wells for other injection purposes, such as in situ bitumen recovery, are now common. To clarify requirements, improve standards, streamline processes, and collect information to support monitoring, the 1994 edition of Directive 051 requires updating.
In the revised edition of Directive 051, the ERCB has
- updated injection well classifications and created a new Class V for injection of steam;
- clarified the application process for the approval of new or converted injection wells;
- enhanced the requirements for wellbore design, wellbore integrity logging, operational monitoring, and reporting
- moving requirements related to the maximum injection pressure and area of review to Directive 065: Resources Applications for Oil and Gas Reservoirs and Directive 023: Guidelines Respecting an Application for a Commercial Crude Bitumen Recovery and Upgrading Project; and
- introduced requirements for ongoing monitoring for some classes of wells.
The Oil & Gas Conservation Regulations and Oil Sands Conservation Regulations will also be revised to support these changes.
The application process for Directive 051 is being reviewed in conjunction with the application process for Directive 065 and will be determined at a later date.
To provide the ERCB with feedback on the draft directive, complete the comment form available on the Directive 051 web page. Feedback or questions on Directive 051 should be sent by e-mail to Directive051@ercb.ca. Feedback will be accepted until November 16, 2012. All feedback received will be reviewed for the purposes noted in the bulletin and may be used for the purpose of revising the directive. All of the comments provided through this consultation will form part of the public record and, at the discretion of the ERCB, any comment received may also be attributed to the specific individuals providing it. Personal information provided with comments will be collected, used, and disclosed in accordance with the Freedom of Information and Protection of Privacy Act. The ERCB may use the personal contact information you provide for follow-up communication related to your feedback.
The ERCB would appreciate that the responses be formatted to identify
- the section of the directive that is of issue, including the page on which it appears,
- what the issue is,
- possible solutions or recommendations, and
- the rationale to support the solution or recommendation.
The draft directive is available for review on the ERCB website at www.ercb.ca. Paper copies of the draft directive are available from ERCB Information Services, Suite 1000, 250 – 5 Street SW; telephone: 403-297-8311; fax: 403-297-7040; e-mail: firstname.lastname@example.org.
