Geothermal production monitoring systems and related methods

A method comprising:

• determining, by executing an instruction with a processor, a property of steam in a multiphase production fluid flowing through a fluid conduit based on sensor data generated by a flowmeter coupled to the fluid conduit and at least one thermodynamic model stored in a database, the at least one thermodynamic model including reference data for correlating the sensor data to the property of the steam, the reference data including thermodynamic properties of the steam and water as a function of pressure and temperature and/or fluids calibration data for the flowmeter, the reference data being defined by one or more user inputs, the production fluid to be generated via a production well including at least one of a downhole pump or a downhole compressor, wherein the sensor data is generated at in-line conditions in the fluid conduit and includes pressure data generated via a first pressure sensor of the flowmeter positioned at a first location along the fluid conduit, pressure data generated via a second pressure sensor of the flowmeter positioned at a second location along the fluid conduit, temperature data generated via a temperature sensor of the flowmeter, and signal data generated via a phase fraction sensor of the flowmeter indicative of phase fractions of the steam and a liquid phase of the production fluid;
• determining, by executing an instruction with the processor, that the property of the steam in the multiphase production fluid is indicative of non-optimal production of the steam;
• determining, by executing an instruction with the processor, a command for at least one of (a) the downhole pump or the downhole compressor or (b) a surface pump in response to the determination that the property of the steam is indicative of the non-optimal production of the steam;
• and
• transmitting, by executing an instruction with the processor, the command to the at least one of (a) the downhole pump or the downhole compressor or (b) the surface pump to increase production of the steam.
