Revised Draft Directive 010: Minimum Casing Design Requirements Available on EUB Web Site for Stakeholder Comment

The Alberta Energy and Utilities Board (EUB) is soliciting feedback on its revised draft Directive 010: Minimum Casing Design Requirements (formerly Guide 10). The EUB had previously invited its stakeholders to review the original draft directive, as discussed in Bulletin 2004-27. As a result of the review of comments and questions provided, changes were made to the original draft. The EUB is now posting this revised draft on the Web for a three-month period for further stakeholder review.

The draft is available on the EUB Web site www.ercb.ca under Rules, Regulations, and Requirements : Directives.

The intent of the proposed revisions is to

• clarify existing requirements set out in the previous version of Guide 10,
• include requirements not in the previous version of Guide 10 but that have become the industry standard, and
• provide the optional use of an alternative design method for casing strings.

Please provide your comments by October 26, 2007, to
Alberta Energy and Utilities Board
Compliance and Operations Branch
640 - 5 Avenue SW
Calgary, Alberta T2P 3G4
E-mail: EUB.WellOperations@gov.ab.ca
Phone: (403) 297-7138

The EUB will review feedback and make appropriate revisions to Directive 010 before publishing the final version. Upon publication, the directive will replace all previous versions of Guide 10. Once the new Directive 010 is published, all licensees and applicants must comply with the new requirements.
