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 water fraction of the multiphase fluid;
determine an expected total water flow rate based on the flow rate of the condensed water within the multiphase fluid;
determine a total water flow rate based on the water fraction;
determine a flow rate of formation water within the multiphase fluid based on a difference between the total water flow rate and the expected total water flow rate;
output one or more output signals indicative of the flow rate of the formation water within the multiphase fluid;
determine a maximum enabled water flow rate based on a flow rate of a hydrate inhibitor into the multiphase fluid;
determine a maximum enabled flow rate of formation water based on the maximum enabled water flow rate and the expected total water flow rate;
determine a maximum enabled change in total water flow rate based on the maximum enabled flow rate of formation water; and
perform an action in response to determining the flow rate of formation water is greater than or equal to a threshold factor multiplied by the maximum enabled change in total water flow rate.
