1. A water detection and measurement system for a resource extraction system, the water detection and measurement system comprising:
a controller comprising a memory and a processor, wherein the controller is configured to:
receive one or more first sensor signals indicative of a pressure of a multiphase fluid;
receive one or more second sensor signals indicative of a temperature of the multiphase fluid;
determine a fraction of condensed water within the multiphase fluid based on the pressure of the multiphase fluid and the temperature of the multiphase fluid;
determine a flow rate of the condensed water within the multiphase fluid based on the fraction of the condensed water within the multiphase fluid and a gas flow rate of the multiphase fluid;
receive one or more third sensor signals indicative of a fluid parameter of the multiphase fluid, wherein the fluid parameter comprises a concentration of a hydrate inhibitor within the multiphase fluid;
determine an expected total water flow rate based on the flow rate of the condensed water within the multiphase fluid; and
determine a flow rate of formation water within the multiphase fluid based on the concentration of the hydrate inhibitor within the multiphase fluid, the expected total water flow rate, and the flow rate of the condensed water within the multiphase fluid; and
output one or more output signals indicative of the flow rate of the formation water within the multiphase fluid.
