Abstract: Progressing cavity devices and systems are provided. In one embodiment, a stator of a progressing cavity device includes metal plates with apertures that are rotationally offset to form a winding rotor conduit for receiving a rotor of the progressing cavity device. A layer of elastomer can be provided on edges of the apertures of the metal plates in the winding rotor conduit, and the stator can also include a gas breakout port through the metal plates to enable gas between the metal plates to escape the stator. Additional systems, devices, and methods are also disclosed.

Abstract: An apparatus for agitating production fluid in a reservoir comprises a pump having a lower pump intake and an upper pump output. A port adapter is connected to the pump output and defines a bypass port in a wall thereof. An output conduit is connected to the port adapter and to a surface facility. A circulating conduit is secured to the pump and connected to the bypass port. A circulating nozzle is connected to the lower end of the circulating conduit and defines an orifice operative to restrict flow through the circulating conduit. The pump intake and circulating nozzle are in the reservoir when production fluid is being pumped, and production fluid flows up the output conduit to the surface facility and also through the circulating conduit and circulating nozzle into the reservoir. A method comprises re-circulating a portion of pumped fluid back into the reservoir to agitate the reservoir.
