1. A method for determining a flow rate of at least a phase or a component of a fluid produced from a well containing at least one of oil or gas, the fluid being at least one of a multiphase fluid or a multicomponent fluid, the method comprising:
during a training phase:
collecting initial primary measurements of pressure, temperature, and at least one additional parameter of the fluid, the collecting being carried out at a wellhead of the well by a set of sensors installed in a flow line for the fluid;
collecting an initial flow rate measurement of the at least the phase or the component of the fluid by a reference multiphase flow meter installed in the flow line, the initial primary measurements and the initial flow rate measurement being collected simultaneously; and
establishing a relationship between:
the initial primary measurements of the pressure, the temperature, and the at least one additional parameter; and
the initial flow rate measurement of the at least the phase or the component of the fluid;
during a production phase, subsequent to the training phase:
determining the flow rate of the at least the phase or the component of the fluid based on:
collecting subsequent primary measurements of the pressure, the temperature, and the at least one additional parameter of the fluid; and
the established relationship; and
controlling the well based on the determined flow rate of the at least the phase or the component of the fluid.
