1. A method, comprising:
obtaining, using a first temperature sensor coupled to a wellhead, first wellhead temperature data from Flail the wellhead in a well system coupled to a wellbore;
obtaining, using a second temperature sensor that is a predetermined distance away from the wellhead, ambient temperature data regarding a wellsite;
obtaining a plurality of well system parameters for the well system at the wellhead;
obtaining first production data regarding the wellhead;
obtaining water cut data from the wellhead;
calibrating, by a well control system coupled to the first temperature sensor and the second temperature sensor, a production model for the wellhead based on the first production data, the ambient temperature data, and the first wellhead temperature data to generate a calibrated production model;
determining, by the well control system, a predicted production rate of the wellhead using the calibrated production model, the water cut data, and flowing wellhead temperature data;
determining, by the well control system and in response to determining the predicted production rate, an adjusted parameter for the well system based on the predicted production rate,
wherein the adjusted parameter corresponds to a well system parameter among the plurality of well system parameters; and
transmitting, automatically by the well control system, one or more commands to a choke assembly in the well system to implement the adjusted parameter.
