Claim 0:
1. A system for dynamic real-time water-cut monitoring comprising:
a plurality of sensors for sensing pressure across a pipe, wherein each of the plurality of sensors is separated by a common distance from a next sensor of the plurality of sensors along the pipe, wherein the pipe facilitates the transfer of fluid, wherein the fluid includes water; and
a computing device that includes a memory component that stores logic that, when executed by the computing device, causes the system to perform at least the following:
determine whether to use a direct approach for determining water-cut; and
in response to determining not to use the direct approach:
determine an initial guess for water-cut;
estimate, from an output of two sensors of the plurality of sensors, at least one dynamic pressure loss between the two sensors;
estimate, from the output of the two sensors, at least one potential energy pressure loss between the two sensors;
estimate a value for water-cut from the at least one dynamic pressure loss and the at least one potential energy pressure loss;
determine whether the initial guess is within a predetermined threshold of the value for water-cut; and
in response to determining that the initial guess is within the predetermined threshold of the value for water-cut, output the value for water-cut.
