Fiscal Metering Systems

Details :

Oil and gas transactions are conducted globally, each and every day. The aim is to do this as accurately as possible. Although there are different methodologies available to the user, it is a known fact that an inaccurate device (or a device that presents a measurement that is less then precise), can cost either the buyer or the seller millions of dollars, due to reading discrepancies.

As not all measuring devices meet the stringent requirements required for fiscal flow measurement, this workshop steps up to the next level, and explores each one of those devices that can meet the current high international standards. These devices are Internationally recognized, and operate within the stringent norms of accuracy, repeatability and auditability.

This training course will highlight:

  • Everything that is specific and relevant to flow conditions at the point of measurement
  • Fiscal measuring technologies currently utilized (from differential pressure right through to Coriolis)
  • The operating principle of each technology with respect to performance, properties, uses, application, installation, calibration, advantages and disadvantages, et cetera
  • How to select the best device for the task at hand?
  • Understand proving, calibration, maintenance, meter runs and other aspects that go together with fiscal flow measurement

The training course focuses on transferring knowledge that is relevant and applicable to fiscal metering systems, in a manner that is deemed to be insightful and meaningful. At all times, the abilities of the delegates are considered, and the instructor interaction and participation revolves around this.

At the end of this course, you will learn to:

  • Develop a full understanding of accepted equipment and technology currently being used
  • Analyze each unique situation, and suggest a working solution that complies with legislation and standards
  • Implement a complete fiscal flow metering system, from conceptual stage to commissioning
  • Apply methods applicable to calibration and auditing, which comply with international best practice
  • Design a fully functional fiscal flow metering system, that complies with the company requirements of each delegate

There are a wide variety of people that will find this training course beneficial. Everyone involved in fiscal flow measuring systems (from management to workers) stand to gain tremendous knowledge from the material being presented.

This course is suitable to a wide range of professionals but will greatly benefit:

  • Managers
  • Engineers
  • Process personnel
  • Commissioning staff
  • Supervisors
  • Financial staff
  • Auditing staff
  • Maintenance staff (of all disciplines)

Day Five: Measurement Systems, Sampling, Proving and Equipment that is Specific to Flow Computing

  • How meter factors influence fiscal measurement
  • The relationship between fiscal measurement and meter runs
  • Proving systems, concentrating on direct, indirect, master meter, volume and displacement proving systems
  • Chromatographs
  • Sampling systems
  • Skids
  • The influence of time delays on certain systems
  • Flow computers, serial data communication and other miscellaneous measurements associated with the school flow measurement

Several training techniques are utilized. Theoretical components are presented in small chunks, which allows for the maximum transfer and retention of information. The use of video material is included, to reinforce theoretical understanding. Practical exercises form the basis of the workshop, and these are either done in an individual or a group environment, depending on how the greatest effect may be achieved. The workshop starts and ends off with a pre-and post-course evaluation, and includes an Internet based assessment at the end of each chapter, to evaluate individual understanding.
