Directive 17 Flashcards
With respect to the AER what are directives?
First statement under Directives
Directives are documents that set out new or amended AER requirements or processes for implementation. Licensees, permittees, and other approval holders under the jurisdiction of the AER are required to obey all directives - See more at: http://www.aer.ca/rules-andregulations/directives#sthash.1eIjYqeY.dpuf
What measurement points are covered in Directive 017?
From FAQs about Directive 017
The requirements in this directive cover all measurement points required by the Oil and Gas Conservation Regulations (OGCR) and other existing regulations for upstream petroleum facilities and some downstream pipeline operations, as well as those used for ERCB accounting and reporting purposes
What is the definition of “delivery point “according to Directive 17?
From the Directive 017 Glossary
Delivery Point - The point at which the delivery of oil or gas production from a battery or facility is measured. The volumes determined at this point are typically used in royalty calculations (royalty trigger points), such as sales, cross border, gas plant to facility, or gas plant to gas plant meters.
Where do producers have to install delivery point measurement systems?
From FAQs
Delivery point measurement is required at royalty trigger points within the upstream oil and gas systems and at cross-border facilities. See Sections 1.7.1 and 1.7.2 for oil and gas delivery points.
What is the definition of “Meter Factor “according to Directive 17?
From the Directive 017 Glossary
Meter Factor - A dimensionless number used to correct indicated meter volumes to adjusted volumes if the two volumes differ due to operational conditions (e.g., gas entrained in liquids, meter slippage, meter wear). It is not to be confused with the “K Factor,” which is used to convert the number of pulses generated by a meter (where electronic pulse technology is the basis of the meter operation) into units of volume. The K Factor is typically determined by the meter manufacturer and does not take into consideration all of the specific operational conditions the meter may be subjected to.
Under Section 1.6 Determination of Uncertainties, 1.6.1 Example Calculation what method of calculation is used for determination of single point measurement for well oil(proration battery)?
1.6.1 Example Calculation
Determination of single point measurement uncertainty for well oil (proration battery) using “root sum square” methodology:
Under section 2.5.3 for an orifice meter chart recorder, if a temperature element is in place, the temperature element must be calibrated at how many points?
If a temperature element is in place, the temperature element must be calibrated at three points (operating temperature, one colder temperature, and one warmer temperature are recommended).
Under section 4.3 Base Requirements for Gas Measurement, 1) what # of AGA report is referenced for Orifice Metering of Natural Gas and Other Related Hydrocarbon Fluids?
1) If an orifice meter system is used to measure gas, it must be designed and installed
according to the applicable AGA Report #3: Orifice Metering of Natural Gas and Other
Related Hydrocarbon Fluids (AGA3) listed in Table 4.1 below.
Under section 4.3 Base Requirements for Gas Measurement, 2) what # of AGA report is referenced for “Linear metering systems, such as a turbine or vortex meter, used to measure gas “?
2) Linear metering systems, such as a turbine or vortex meter, used to measure gas must be designed and installed according to the provisions of the 1985 or later editions of the AGA Report #7: Measurement of Gas by Turbine Meters (AGA7) or the manufacturer’s recommendation.
Under section 4.3.2 Volumetric Calculations, if an orifice meter is used to measure the gas , what year or later must be used of the AGA3 to calculate the gas volumes?
If an orifice meter is used to measure gas, the licensee must use the 1985 or later editions of the AGA3 to calculate the gas volumes.
The ERCB (AER) Enforcement process is specified in which directive?
Enforcement The ERCB enforcement process is specified in Directive 019: Compliance Assurance. Noncompliance events are listed in the Risk Assessed Noncompliance section of Directive 019 under the Technical Operations Group, Production Operations Section, for Directive 017 and Directive 007 requirements.
