Abstract: An electric submersible pump (ESP) including: a switched reluctance motor (SRM) including stator coils. The number of the stator coils is a multiple of three, surface electronics that drive the SRM, a cable that connects the SRM to the surface electronics. The cable includes conductors in a number equal to the number of the stator coils, each cable includes a push-pull driver that connects the cable to a ground, a DC voltage different from the ground, or disconnects the cable.

Abstract: An apparatus for fluid measurement is disclosed. The apparatus includes a leaf cell sensor having one or more piezoelectric radial components connected to a circumferential component, a first electrode positioned on a distal face of at least one radial component, a second electrode positioned on a proximal face of the at least one radial component, a voltage source having a negative terminal and a positive terminal, the negative terminal being connected to the first electrode and the positive terminal being connected to the second electrode, an electric current measurement device connected to the first and second electrode to measure current flowing between the first and second electrode, and a processor of a computing device that determines, from the measured current, one or more properties of the fluid, where the voltage source couples electrical energy into the one or more piezoelectric radial components at multiple frequencies concurrently.

Abstract: An electric submersible pump (ESP), comprising: an intake that suctions fluids into the ESP, wherein the fluids include a mixture of gas, water, and oil; a discharge that discharges the fluids from the ESP; an acoustic intake transducer that determines the speed of sound in the fluids suctioned into the ESP at the intake; and a first acoustic discharge transducer that determines the speed of sound in the fluids discharged from the ESP, wherein the speed of sound of the fluid at both intake and discharge is used to calculate a gas volume fraction difference of the multiphase fluid mixture across the intake and discharge of the pump, and wherein the gas volume fraction difference is used as feedback to control the ESP.
