    摘要: Examples of techniques for extracting hydrocarbons from a subterranean hydrocarbon reservoir based on an artificial lift plan are disclosed. In one example implementation according to aspects of the present disclosure, a method includes performing, by a processing device, an evaluation of an artificial lift approach that can be operated at a well having a subterranean hydrocarbon reservoir, the evaluation being based at least in part on a static factor associated with operating the artificial lift approach in the well and a dynamic factor associated with operating the artificial lift approach at a operating condition. The method further includes generating, by the processing device, an artificial lift plan based at least in part on the evaluation. The method further includes extracting the hydrocarbons from the subterranean hydrocarbon reservoir based on the artificial lift plan by operating, at the well, the artificial lift approach.

    摘要: An assembly for positioning a retaining ring includes a mandrel having an outer diameter smaller than an outer diameter of a rotor. The assembly also includes a seal assembly for sealing a circumferential retaining ring around the mandrel or the rotor, the seal assembly comprising a pair of seal plates situated around opposing ends of the retaining ring. Further, the assembly includes a hydraulic expansion device for providing a fluid pressure for hydraulically expanding the retaining ring until an inner diameter of the retaining ring is greater than the outer diameter of the rotor. Furthermore, the assembly includes a displacement device for providing axial movement of the seal assembly and the retaining ring.

    摘要: A midlength balanced rotor comprises a rotor assembly for rotation about an axis of rotation defining at least one of an axially extended, radially concentric, centerline borehole; an array of radially or tangentially distributed, axially extended pockets; and a series of radially or tangentially distributed, axially extended slots. At least one balance weight is positioned within at least one of the axially extended, radially concentric, centerline borehole, the array of radially or tangentially distributed, axially extended pockets, or the radially or tangentially distributed, axially extended slots to balance the rotor assembly. Alternatively, at least one balance correcting mass is removed from at least one of the axially extended, radially concentric, centerline borehole, the array of radially or tangentially distributed, axially extended pockets, or the radially or tangentially distributed, axially extended slots to balance the rotor assembly. In addition, a method of midlength balancing a rotor comprises the steps of providing a rotor assembly with at least one of an axially extended, radially concentric, centerline borehole; an array of radially or tangentially distributed, axially extended pockets; and a series of radially or tangentially distributed, axially extended slots; rotating the rotor shaft about an axis of rotation; determining unbalance of the rotor shaft; and adding or removing weight to at least one of said an axially extended, radially concentric, centerline borehole; array of radially or tangentially distributed, axially extended pockets; or series of radially or tangentially distributed, axially extended slots, to balance the rotor shaft.
