Revised Edition of Directive 017: Measurement Requirements for Oil and Gas Operations Issued
This bulletin announces the release of the revised edition of Energy Resources Conservation Board (ERCB) Directive 017: Measurement Requirements for Oil and Gas Operations, which replaces the edition issued on April 18, 2011, and is effective immediately. In the September 2012 edition, Sections 1.9, 1.10, and 18.104.22.168 (described below) as well as Appendices 9 and 10, are new; Section 7.4 has been extensively revised; and clarifications to the pre-existing 15 sections of Directive 017 have been made.
Due to the complexity of consolidating and clarifying existing requirements and updating them to take into account the current technological and operating environments, this directive is being developed in stages, with new sections added as they become available. Feedback on draft additions and revisions to Directive 017 released for review on January 31, 2012, were considered in finalizing the September 2012 edition of the directive.
The revised edition of Directive 017, as well as a summary of the feedback received on the drafts and the ERCB’s responses, is available on the ERCB website at www.ercb.ca. Printed copies of the directive may be purchased from ERCB Information Services, Suite 1000, 250 – 5 Street SW; telephone: 403-297-8311 or 1-855-297-8311 (toll free); fax: 403-297-7040; e-mail: email@example.com.
In the version available on the ERCB website, all changes made in editions published from 2007 to October 2011 appear in red type and all changes made since the previous edition (April 2011) appear in blue type.

Section 1.9: Measurement Schematics – This section presents the requirements and exceptions for measurement schematics used for measurement, accounting, and reporting of oil and gas facilities.
Section 1.10: Facility Delineation Requirements – This section presents the guidelines for delineating lease sites and geographic areas into reporting facilities. It is based on the measurement, accounting, and reporting requirements described in this directive and Directive 007.
Section 184.108.40.206: Gas Lift Systems for Both Oil and Gas Wells – This section presents the requirements for four gas source scenarios for lift gas, and each one may be subjected to different measurement, reporting, and sampling and analysis requirements when gas is injected into the wellbore to assist in lifting the liquids to the surface.
