Producing Fluids from Subsurface Reservoirs Using Electric Submersible Pumps

A method for producing fluid from a well using an electric submersible pump, the method comprising:

• receiving, by a processor, results of a portable separator rate test in the well to obtain an operating point for the electric submersible pump in the well;
• receiving, by the processor, a performance curve for the electric submersible pump;
• adjusting, by the processor, the performance curve for the electric submersible pump based on specific gravity and viscosity of fluid being produced from the well;
• calculating, by the processor, a head correction necessary to shift the adjusted performance curve to pass through the operating point obtained from the portable separator rate test;
• updating, by the processor, a model of the electric submersible pump by incorporating the calculated head correction;
• and
• executing, by the processor, the model of the electric submersible pump to predict flow rates from the well at surface conditions.
