Accurate and reliable gas measurement depends on a combination of efforts from two groups of people. First, we have the field personnel. They have the responsibility of seeing that a readable chart is produced and that all information pertinent to volume calculation is supplied to our next group, which is the office personnel. This group […]

Whether lightning damage or lightning voltages induced between equipment cabinets as a result of multi-grounding causing mis-operation of computerized electronics, improper grounding can account for up to 40 percent of power-related problems including costly damage and downtime. In addition, transient overvoltages—a high voltage spike or impulse of very short duration—can account for another 40 percent […]

Convergence in the Oil and Gas Sector Today’s oil and gas industry faces increasing pressure to maximize the capability of its wireless infrastructure while minimizing operational and developmental costs. Unprecedented uncertainty and business volatility are transforming the landscape, as the oil and gas industry becomes more competitive, profit-oriented, and responsive to a fickle and savvy […]

The natural gas industry’s adoption of EGM as a means of increasing the speed and accuracy with which measurement information is obtained, has created the need for an electronic data management system. Properly designed and implemented, a measurement data management system adds functionality that complements the power of the hardware. With proper implementation, such a […]

This paper presents methods for determining the uncertainty of both differential and linear metering stations. It takes into account the type of meter, number of meters in parallel, type of secondary instruments, and the determination of physical properties. The paper then relates this information to potential influence on system balance

The gas industry today is constantly changing, with increasing demands on office and field personnel. Initially there was FERC (Federal Energy Regulatory Commission) Order 636 that forced the gas measurement departments into the electronic age. Next, corporate downsizing has required the gas measurement groups to perform at the same level of integrity in the measurement […]

This paper provides an overview of many aspects of SCADA systems. It begins with defining the systems while also covering communications technologies, system design and radio equipment

Technology in the field of gas measurement and control is constantly evolving. While many are well training in the specific equipment used in their own company’s operation, it is important to have a solid understanding of the fundamentals and theory of operation of the mechanical and physical process involved as well. Therefore, the training of […]

Pipeline and production companies are continually faced with challenge of obtaining operational data and making it available to their employees. In recent years the convergence in the advances in the technologies of the Internet, PC’s, client/server technology, and IP ready communications have brought forth a new lower cost alternative to traditional SCADA systems. With the […]

Electronic Gas Measurement or EFM auditing is a very important process of the natural gas industry. Only a few short years ago, the dry flow chart recorder was the “state of the art” recording device for custody gas measurement. All that has changed with the advent of the flow computer; volumes are recorded and generated […]
