Abstract: An airgap cooling system (140) for an electric machine (100), the electric machine (100) including a rotor assembly (102) rotatably mounted within a stator assembly (120) and defining an airgap (130) therebetween, wherein the stator assembly (120) comprises a lamination stack (124). The airgap cooling system (140) includes a plurality of distribution passages (142) that extend through the lamination stack (124); a plurality of discharge passages (150) that extend between the plurality of distribution passages (142) and the airgap (130); a cooling manifold (160) defining an annular distribution plenum (164) in fluid communication with the plurality of distribution passages (142), wherein the cooling manifold (160) is configured for receiving a cooling fluid (144) and directing the cooling fluid (144) into the distribution plenum (164), through the distribution passage (142) and the discharge passage (150), and into the airgap (130).

Abstract: An engine includes: a first rotating component; a second rotating component separate from the first rotating component; and an electric machine, the electric machine including a first rotor rotatable with the first rotating component; a second rotor rotatable with the second rotating component; and a stator assembly arranged between the first rotor and the second rotor, the stator assembly including a first set of windings arranged adjacent to the first rotor, a second set of windings arranged adjacent to the second rotor, and a non-ferromagnetic inner housing arranged between the first set of windings and the second set of windings.

Abstract: A flow control system is provided for a horizontal well production system having a casing, a tube having an intake opening and disposed within the casing, and a gap formed between the casing and the tube. The flow control system includes a valve having an orifice, coupled to the tube and disposed proximate to the intake opening. The flow control system further includes an actuator coupled to the valve and configured to open the valve in response to a presence of a liquid in the gap, proximate to the intake opening, to permit flow of the liquid into the tube via the intake opening, and to close the valve in response to a presence of a gas in the gap, proximate to the intake opening, to prevent flow of the gas into the tube via the intake opening.

Abstract: A system includes a stator core, which includes a plurality of teeth and a plurality of bridges. The plurality of teeth are disposed about an axis of the stator core, wherein each tooth of the plurality of teeth extends in a radial direction from a proximal end to a distal end. Each bridge of the plurality of bridges is disposed between two adjacent teeth and connects the proximal ends of the two teeth. The plurality of teeth and the plurality of bridges define a plurality slots, each having a proximal end and a distal end, wherein the proximal end of each slot is closed and the distal end of each slot is open.

Abstract: A method of isolating a production fluid from a fluid-containing reservoir is provided. The method includes disposing a first pump within a horizontal section of a production well. The method also includes disposing a second pump within a vertical section of the production well. Further, the method includes pumping a reservoir fluid via the first pump towards the second pump. The method also includes capturing at least a portion of the reservoir fluid from the first pump in a fluid-retaining section located around the second pump. Furthermore, the method includes pumping the reservoir fluid captured in the fluid-retaining section to a fluid containment vessel via the second pump to provide an isolated production fluid.
