Abstract: Rotor bearings are provided. The motor bearing can be used in an electric submersible pump motor. The bearing can include a body and one or more anti-rotation pins disposed partially in a groove in an outer surface of the body and configured to be received in a corresponding keyway in an inner diameter of a stator. The anti-rotation pin prevents or inhibits rotation of the bearing relative to the stator.

Abstract: Geothermal production monitoring systems and related methods are disclosed herein. An example system includes a production well, an injection well, a downhole pump or a downhole compressor to control a production of a multiphase fluid including steam from the production well, a first fluid conduit to transport the multiphase fluid away from the production well, a surface pump disposed downstream of the first fluid conduit, and a second fluid conduit. The surface pump is to inject water into the injection well via the second fluid conduit. A flowmeter is fluidly coupled to the first fluid conduit. The example system includes a processor to control at least one of (a) the downhole pump or the downhole compressor or (b) the surface pump in response to fluid property data generated by the first flowmeter.
