This training is for any personnel who is new to natural gas measurement and metering activities in the oil and gas sector. There are two critical parameters when dealing with the value of natural gas: quality and quantity. The quantity and quality of natural gas must be measured for operational and fiscal purposes. The conditions under which natural gas measurement devices operate are usually unsteady because of the variation in fluid properties and flow conditions. This instability and variation in the behavior of natural gas affect how flow measurement equipment performs in service.
Critical to understanding natural gas flow measurement is the fundamental principles upon which measurement devices operate. The physical properties of natural gas are critical to the performance of flow measurement and metering devices. To adequately operate natural gas measurement, the field personnel must understand the fundamentals of natural gas measurement; and then build this understanding all the way to advanced levels. This course covers natural gas flow measurement basics and provides the foundation for understanding what constitutes the best petroleum measurement practices. The training would refer to international standards such as API MPMS, ISO, AGA, BS, ASME, and ASTM.
Understand the physical properties and behavior of natural gas, gas flow in pipes, and the application of gas laws in metering.
Learn about gas quality measurement, including technology for temperature, pressure, density, and the measurement of heating value using gas chromatography.
Grasp basic measurement concepts and their application in evaluating the performance of flow measurement and metering systems.
Explore different types of meters and their selection criteria, along with regulatory requirements and international best practices.
Gain knowledge of inspection, proving/calibration processes, and best practices for instrument calibration and flow meter proving.
Understand operational issues and the application of metering in sales gas and custody transfer, gas accounting, and the role of good measurement practices in gas pipeline operation operations.
