1. A method for determining a flow rate of at least a phase or a component of a fluid produced from an oil and gas well, wherein the fluid is at least one of a multiphase fluid or a multicomponent fluid, the method comprising:
during a training phase:
collecting first primary measurements of pressure, temperature, and at least one additional parameter of the fluid, wherein:
the collecting is at a wellhead of the oil and gas well by a set of sensors installed in a flow line for the fluid; and
the at least one additional parameter of the fluid includes at least one of: effective fluid flow rate, velocity, effective density of a mixture, volume fraction, component viscosity, effective viscosity, dielectric permittivity, or conductivity of one or more phases or components of the fluid;
collecting first measurements of flow rate of the at least the phase or the component of the fluid by a reference multiphase flow meter installed in the flow line, wherein the first primary measurements of the pressure, the temperature, and the at least one additional parameter of the fluid and the first measurements of the flow rate are measured simultaneously; and
establishing a relationship between the first primary measurements of the pressure, the temperature, and the at least one additional parameter of the fluid and the first measurements of the flow rate of the at least the phase or the component of the fluid;
during a production phase, subsequent the training phase:
collecting second primary measurements of the pressure, the temperature, and the at least one additional parameter of the fluid, wherein the collecting is at the wellhead of the oil and gas well by the set of sensors installed in the flow line for the fluid; and
determining the flow rate of the at least the phase or the component of the fluid based on the second primary measurements of the pressure, the temperature, and the at least one additional parameter of the fluid and on the established relationship; and
controlling the oil and gas well based on the flow rate of the at least the phase or the component of the fluid.
