Abstract: Disclosed are methods and devices for testing downhole connector electrical systems and cable integrity during installation of a permanent completion, including a customized retrievable plug arm assembly connectable to the completion during RIH, the tool mimicking a retrievable ESP, but without motor, and can be employed with or without pressure isolation. Another method employs a slidable starpoint located within the downhole wet mate connector of the completion to provide continuous electrical contact between the phases when no retrievable assembly is in place. When a retrievable assembly is later put in place, the slidable starpoint is moved into a second position that no longer provides electrical contact between the phases. Another method uses fusible links installed between two conductors within the downhole electrical connector system of the completion to provide similar electrical contact between phases, the fusible link configured to melt away once motor current is sent through the conductors.

Abstract: A method for making a wet mate electrical connection in an underground borehole with a static downhole conductor pin that is protected from the borehole environment by a non-sealed shuttle and a moveable mating receptacle/conductor which presses on the outer body of the shuttle thus causing it to move along the conductor pin tube. The conductor pin inserts into the receptacle connector and connects to the contacts. Both connectors are filled with a dielectric fluid for isolation and are pressure balanced to counteract volume variation due to temperature changes. The moveable receptacle connector uses a non-conductive pin which is replaced by the conductor pin and provides a surface for wiper seals. As mating occurs, the conductor pin replaces the non-conductive pin, so no volume change occurs, and pressure change is eliminated. A reverse labyrinth isolates the heavy dielectric of the static connector from borehole fluid.
