AI Technical Summary

Technical Problem

Electrical connectors in electrical submersible pump assemblies often fail due to elevated temperatures or contamination, leading to production halts and the need for complete replacement of the completion system, which is time-consuming and costly.

Method used

A completion assembly with multiple electrical conductors and a downhole electrical connector selector that can switch between redundant connectors to maintain power flow to the electrical submersible pump assembly, allowing for selective replacement and reconfiguration without removing the entire production tubing.

Benefits of technology

Reduces downtime and improves reliability by enabling efficient reconfiguration and maintenance of power supply to the electrical submersible pump assembly, simplifying workover operations, and enhancing the cleanliness of downhole connectors.

Abstract

A completion assembly to be disposed in a wellbore to produce a hydrocarbon. The completion assembly has electrical conductors, a docking station for an electrical submersible pump assembly, and a downhole electrical connector selector. The docking station is coupled to the electrical conductors in the wellbore and has multiple electrical connectors to flow electricity from the electrical conductors to the electrical submersible pump assembly. The downhole electrical connector selector couples to the docking station between the docking station and the electrical submersible pump assembly. The downhole electrical connector selector is configurable to switch between a first subset of the electrical connectors and a second subset of electrical connectors to control a flow of electricity from the electrical connectors of the docking station to the electrical submersible pump assembly to maintain the flow of electricity to the electrical submersible pump assembly.
