Abstract: An electric submersible pump (ESP) assembly. The ESP assembly comprises a seal section that comprises a housing and at least one sacrificial anode assembly. The at least one sacrificial anode assembly comprises a sacrificial material suitable to attenuate the corrosive effect of H2S fluid (hydrogen sulfide) and comprises a containment disposed inside the housing. The containment defines an annulus between an outside of the containment and an inside of the housing. The containment is disposed around the sacrificial material. The containment defines interiorly an initially void space downhole of the sacrificial material. The at least one sacrificial anode assembly defines a folded fluid flow path through the sacrificial material.

Abstract: A system can be used in a wellbore. The system can include a first thrust chamber, a second thrust chamber, and a seal guide. The first thrust chamber can include a first bearing for absorbing thrust in a first direction in the wellbore. The second thrust chamber can include a second bearing for absorbing thrust in a second direction in the wellbore that is different than the first direction. The seal guide can be positioned between the first thrust chamber and the second thrust chamber to separate the first thrust chamber from the second thrust chamber. The seal guide can protect the second thrust chamber and can provide radial support for a shaft that can be positioned in the first thrust chamber and the second thrust chamber.

Abstract: Techniques for using user configurable reflection operations to access layered information are disclosed. A user may identify a method and type to be monitored in an application in a configuration file that is uploaded to the APM agent. The APM agent parses the configuration file to determine the method and type to be monitored and to identify any trace method. The APM agent may configure an execution environment to invoke a trace method upon the invocation of a target method. The trace method may execute a reflective operation and/or chained reflective operations to collect and report application information.

Abstract: A connector for connecting electrical power to a well pump motor has cable and motor connector portions that mate with each other in a connected position. The connector portions have insulating members, each of which has a number of passages and an end face. Electrical contact members are mounted in each of the passages. Contact members in the cable connector portion protrude past the end face of the insulating member. A debris seal insulates the electrical contact members in the cable connector and includes expansion slots so that when the material of the debris seal thermally expands, the expansion slots contract in response to the expansion without the debris seal impinging against either connector.

Abstract: Ensuring that a given transactional unit of work arrives at an appropriate server instance. A server instance receives a request that is associated with a unit of work. The server instance that received the request determines whether it is responsible for the unit of work associated with that request. When the server instance is responsible for the unit of work, the server instance processes the request. When the server instance is not responsible for the unit of work, it attempts to register its interest in the unit of work. If this attempt is successful, then the server instance can process the request. If the attempt is unsuccessful, then the responsible server instance is located and the request is forwarded to the responsible server instance.

Abstract: An electrical power probe is provided. In one aspect, an electrical power probe includes a power probe control unit adapted to connect to a direct current (DC) power source and receive an input source voltage from the DC power source. The power probe control unit comprises a power switch controlling the switching of the input source voltage to a cable. A power probe wand includes a conductive wand tip and a user controlled switch, with the wand tip being connected to the power switch by the cable. The power probe control unit sends a query message to the power probe wand. The power probe wand unit sends a response to the power probe control unit in response to the query message, with response indicating the position of the user controlled switch. The power probe control unit selectably switches the power switch based on the position of the user controlled switch.
