Abstract: Disclosed are configurations of tools, e.g., as used in the tool strings of electrical submersible pump systems, that prevent the separation of the tool string into two disconnected units upon breaking of a tool within the tool string. In an example configuration according to one embodiment, such a non-parting tool includes a head and base connected to each other via a housing and a shaft extending through the tool, as well as mechanical stops affixed to the shaft that limit, upon breaking of the housing, the relative motion between the head and base. Additional apparatus, systems, and methods are disclosed.

Abstract: An electric submersible pump including a housing having a longitudinal axis extending therethrough; and a plurality of stages disposed within the housing each stage having an impeller and a diffuser, the plurality of stages stackable one upon the other along the longitudinal axis of the housing, wherein one or more of the plurality of stages is a standard flow stage, wherein one or more of the plurality of stages is an anti-gas lock flow stage, and wherein the anti-gas lock flow stages are modified relative the standard flow stages to have decreased incidence of trapped gas.

Abstract: An electric submersible pump having a housing with side walls and at least one stackable diffuser residing within the housing. The stackable diffuser can have a diffuser side wall forming an annular gap between the outer surface of the diffuser side wall and the inner surface of the housing side wall. A filler can be provided within the annular gap to prevent recirculation and/or rotation of the diffuser within the housing. Additionally or alternatively, an O-ring can be disposed within the annular gap to prevent recirculation and/or rotation of the diffuser within the housing.
