Off-grid telemetry system for hydrate inhibition on gas wells

Abstract

Field installed systems work remotely from the supervisory station. These systems work autonomously, but usually it is necessary to inform the supervisory station about their working conditions. Furthermore, the term off-grid refers to being unconnected to the electrical grid. It is essential to keep the energy balance in positive. A prototype system has been developed to prevent formation of hydrate plugs on gas wells in Hungary. The article describes the telemetry system and includes some programming technics and practices.
