    Abstract: A method involves mixing metallic particles and a liquefied polymer to form a mixture, placing the mixture within a mold, placing a magnet in the vicinity of the mixture within the mold, thereby causing the metallic particles to position themselves in a self-assembly formation within the mixture in response to a magnetic field generated by the magnet, and solidifying the liquefied polymer, such that a polymer matrix is formed. The metallic particles are distributed and secured in the self-assembly formation throughout the polymer matrix, thereby forming a ballast for an untethered downhole tool configured to be lowered into a well formed in a subterranean formation. The polymer matrix is configured to dissolve in response to being exposed to downhole fluid within the well at specified downhole conditions.

    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.

    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.
