Abstract: Systems and methods for finding and solving problems with wet gas venturi meters in one or more gas well sites include one or more gas well sites configured to supply gas to a gas plant, each gas well site comprising a gas well connected to a piping, one or more valves installed on the piping, one or more pressure sensors, one or more temperature sensors, one or more venturi meters configured to measure a differential pressure of the gas in the piping. The system is configured to directly use the field instrument data (P, T, dP) and use dimensions of venturi meter and the fluid properties values of gas wells, and calculate the gas flow and gas condensate of the wells.
