As the global demand for oil and natural gas increases, the drive to maximize output continues to push operations further into remote areas. Wellhead monitoring of water injection, gas injection and gas lift wells for EOR, and field management optimization, both onshore and offshore, improves efficiencies, helps field management, and ensures operational safety. High pressures, abrasive media, complex networks, and demand for real time optimization, are just some of the injection well monitoring challenges inline/ wetted instrumentation face in the Upstream sector. FLUXUS clamp-on meters for oil and gas field service management are mounted on the outside pipe wall, therefore avoiding contact with the flowing media’s wear and tear, while providing accurate and reliable flow rates without the risk of losing production and no need for regular maintenance.
