Lower Connector
For the REDA Coil coiled-tubing-deployed ESP system
APPLICATIONS The lower connector of the REDA Coil system provides the mechanical
■■ REDA Coil* coiled-tubing-deployed connection between the coiled tubing and the ESP string. It also provides the
ESP system electrical connection between the ESP motor and the cable inside the coiled
tubing.
BENEFITS
