Abstract:
Systems and methods for generating pressure data from at least two pressure sensors, storing one or more parameters indicative of water cut in a neural network model, receiving pressure data from at least the two pressure sensors respectively indicative of the pressure at two points of a well bore, determining a pressure drop between the two points, generating an input water cut estimate, estimating a dynamic pressure loss to initiate an iterative process, estimating a potential energy loss, inverse modeling a water cut estimate, comparing the water cut estimate to the input water cut estimate to generate a water cut Δ, utilizing the water cut estimate as the input water cut estimate for the iterative process when the water cut Δ exceeds a threshold, and continuing the iterative process until the water cut Δ is below the threshold.
