Claim 18:
19. The method of claim 18, wherein determining at least one of the gas phase inflow, the aqueous phase inflow, or the hydrocarbon liquid phase using the fluid flow model comprises:
using the first subset of the plurality of frequency domain features at the identified one or more fluid inflow locations in the first multivariate model;
using the second subset of the plurality of frequency domain features at the identified one or more fluid inflow locations in the second multivariate model;
using the third subset of the plurality of frequency domain features at the identified one or more fluid inflow locations in the third multivariate model;
comparing the plurality of frequency domain features to an output of the first multivariate model, an output of the second multivariate model, and an output of the third multivariate model; and
identifying at least one of the gas phase inflow, the aqueous phase inflow, or the hydrocarbon liquid phase inflow based on the comparison of the plurality of frequency domain features to the output of the first multivariate model, the output of the second multivariate model, and the output of the third multivariate model.
