Systems and methods for wireless deployment of electrical lower completions are provided. A wet disconnect tool-running tool includes a battery and telemetry section, and electronics and sensors section, and a pressure compensator and control lines section.

Wireless electrical lower completion deployment

A technique facilitates smart alarming, event detection, and/or event mitigation. The smart alarming may be achieved by, for example, automating detection processes and using advanced signal processing techniques. In some applications, event detection is enhanced by combining different alarms to facilitate diagnosis of a condition, e.g. a pump condition. The occurrence of certain unwanted events can be mitigated by automatically adjusting operation of a well system according to suitable protocols for a given event.

Well alarms and event detection

Event-based telemetry for artificial lift in wells is described. An example downhole system can sense triggering events and anomalies in a well or electrical submersible pump (ESP) string, and send information about the triggering event with priority to a monitoring and control system. A telemetry manager can select specific sensors to address the triggering event, and then determine how frequently the selected sensors acquire or sample sensor data. The telemetry manager may then assemble a data stream that prioritizes the sensor data for transmission on limited bandwidth, thereby sending the most important data about the triggering event with the highest priority, even when there is limited transmission bandwidth available.

Event-based telemetry for artificial lift in wells

A modular donwhole tool system with a single electric hydraulic drive assembly. The assembly includes an electric hydraulic interface for coupling to any of a variety of different modular donwhole tools. Such tools may include a plug setting actuator, sleeve shifting actuator, valve effecting actuator and a variety of other radially or axially driven hydraulically powered actuators. Indeed, a variety of different actuators may be combined within the same system, tailored based on given downhole application needs. Thus, a viable off-the-shelf modular based on-site assemblage may be available to an operator for running off of a single electric hydraulic drive assembly.

A system can include a transformer and a rectifier to derive DC power from AC power at a wye point of an electric motor; a sensor that includes a sensor signal output to output a sensor signal; a telemetry driver that includes a DC power input to receive the derived DC power and that includes an input to receive the sensor signal and an output to output a data signal representing the sensor signal; and circuitry to deliver the data signal representing the sensor signal to the wye point of the electric motor. Various other apparatuses, systems, methods, etc., are also disclosed.
