Abstract: A downhole tool comprises a housing defining a flow path therethrough in an axial direction from an upper opening to a lower opening. A poppet valve is mounted within the housing. The poppet valve includes an upper member defining an upper chamber mounted in the flow path so that flow through the flow path flows around the upper member, and a valve seat mounted in the flow path with an opening therethrough. A valve poppet is mounted for longitudinal movement within the flow path between a closed position in which the valve poppet seats against the valve seat to block flow through the flow path and an open position in which the valve poppet is spaced apart from the valve seat to permit flow through the flow path. This can restrict/mitigate sand fall-back, e.g., with flow paths designed to prevent/mitigate sand fall-back and for protection of the poppet from sand/debris.

Abstract: The disclosed embodiments include a power and data delivery system for downhole gauges of a well. The power and data delivery system includes a three-phase power supply coupled to a power cable to supply power to a downhole motor positioned along a wellbore. Additionally, the power cable transmits power and data signals. The power and data delivery system also includes a downhole gauge coupled to the downhole motor, and the downhole gauge transmits downhole data signals along the power cable to a gauge surface panel. Further, the power and data delivery system includes at least one gauge positioned remotely from the downhole gauge and coupled to the power cable. The at least one gauge also transmits gauge data signals along the power cable to the gauge surface panel.

Abstract: A sand bridge inducer for a downhole tool can include a wall defining a main opening therethrough and one or more angled passageways defined through the wall such that the one or more angled passageways open from a radially inward opening and traverse axially downward through the wall toward a radially outward opening.

Abstract: A downhole tool for sand fall-back prevention can include a sand bridge inducer configured to be mounted in a flow path through a housing in a downhole tool. The sand bridge inducer can define a longitudinal axis and having a main opening therethrough, wherein the sand bridge inducer includes one or more angled passageways defined through a wall of the sand bridge inducer that are oblique relative to the longitudinal axis. The sand bridge inducer can be segmented with a respective upper segment and lower segment at each respective one of the one or more angled passageways, wherein the respective upper and lower segments are connected to one another across the respective angled passageway for movement along the longitudinal axis relative to one another to enlarge the respective angled passageway for accommodating passage of larger particles and/or relieving pressure differentials caused by high flow rates and/or solids restricting flow.

Abstract: 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, 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.

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.

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: A submersible pump test bench capable of testing multiple lengths of submersible pumps. The test bench includes a series of trolleys that may be moved along, added to, or removed from a rail depending on the length of submersible pump to be tested. The test bench further includes a hose handler for redirecting a length of hose connecting the submersible pump to a broader hydraulic circuit. In certain embodiments, the hose handler includes a rotating sheave or similar structure that redirects the hose back on itself, providing a length-multiplying effect.
