Canada Oil and Gas Drilling and Production Regulations (SOR/2009-315)

Regulations are current to 2015-11-16 and last amended on 2009-12-31. Previous Versions

Well Completion

  •  (1) An operator that completes a well shall ensure that

    • (a) it is completed in a safe manner and allows for maximum recovery;

    • (b) except in the case of commingled production, each completion interval is isolated from any other porous or permeable interval penetrated by the well;

    • (c) the testing and production of any completion interval are conducted safely and do not cause waste or pollution;

    • (d) if applicable, sand production is controlled and does not create a safety hazard or cause waste;

    • (e) each packer is set as close as practical to the top of the completion interval and that the pressure testing of the packer to a differential pressure is greater than the maximum differential pressure anticipated under the production or injection conditions;

    • (f) if practical, any mechanical well condition that may have an adverse effect on production of oil and gas from, or the injection of fluids into, the well is corrected;

    • (g) the injection or production profile of the well is improved, or the completion interval of the well is changed, if it is necessary to do so to prevent waste;

    • (h) if different pressure and inflow characteristics of two or more pools might adversely affect the recovery from any of those pools, the well is operated as a single pool well or as a segregated multi-pool well;

    • (i) after initial completion, all barriers are tested to the maximum pressure to which they are likely to be subjected; and

    • (j) following any workover, any affected barriers are pressure-tested.

  • (2) The operator of a segregated multi-pool well shall ensure that

    • (a) after the well is completed, segregation has been established within and outside the well casing and is confirmed; and

    • (b) if there is reason to doubt that segregation is being maintained, a segregation test is conducted within a reasonable time frame.

Subsurface Safety Valve

  •  (1) The operator of an offshore development well capable of flow shall ensure that the well is equipped with a fail-safe subsurface safety valve that is designed, installed, operated and tested to prevent uncontrolled well flow when it is activated.

  • (2) If a development well is located in a zone where permafrost is present in unconsolidated sediments, the operator shall ensure that a subsurface safety valve is installed in the tubing below the base of the permafrost.

Wellhead and Christmas Tree Equipment

 The operator shall ensure that the wellhead and Christmas tree equipment, including valves, are designed to operate safely and efficiently under the maximum load conditions anticipated during the life of the well.



 The operator shall ensure that the well data acquisition program and the field data acquisition program are implemented in accordance with good oilfield practices.

  •  (1) If part of the well or field data acquisition program cannot be implemented, the operator shall ensure that

    • (a) a conservation officer is notified as soon as the circumstances permit; and

    • (b) the procedures to otherwise achieve the goals of the program are submitted to the Board for approval.

  • (2) If the operator can demonstrate that those procedures can achieve the goals of the well or field data acquisition program or are all that can be reasonably expected in the circumstances, the Board shall approve them.
