Natural Gas Transmission and Distribution Metering

 

COURSE OVERVIEW

 

The efficient, safe, and commercially viable delivery of natural gas from midstream facilities to end-users depends on the precision and reliability of transmission and distribution systems. Accurate metering, optimal flow measurement, and effective loss minimization are not just technical necessities—they are business imperatives that directly impact profitability and regulatory compliance.

However, metering in gas transmission presents complex challenges due to high flow rates, fluctuating gas compositions, and varying transport conditions, making accurate measurement both critical and demanding. On the distribution side, managing multiple delivery points while ensuring precise billing and minimizing gas losses adds another layer of complexity. 

This comprehensive course provides professionals with in-depth knowledge and practical expertise in gas transmission and distribution operations, modern metering technologies, and global best practices in measurement and auditing. Participants will gain actionable insights into optimizing system performance, improving financial accountability, and ensuring compliance with industry standards.

 

EXPECTED LEARNING OUTCOMES

 

By the end of this course, participants will:

  •  Develop a comprehensive understanding of how gas flow characteristics and physical properties affect accurate metering in commercial operations and how to minimise those effects.
  • Learn the principles, selection criteria, and operational challenges of various metering technologies.
  • Understand the impact of temperature, pressure, density, and gas compressibility on measurement accuracy and commercial billing, while learning how to calculate and analyze BTU content.
  •  Deepen your understanding of meter proving, gas flow meter instrument calibration, and industry best practices for ensuring accurate and reliable measurements across gas transmission and distribution networks.
  • Develop skills to calculate line pack, manage capacity allocation, address unaccounted-for losses, and apply international best practices in measurement reporting, auditing, and regulatory compliance.
