More Information
Summary:A method for installing an electrical submersible pump (ESP) in a well containing a production conduit includes securing an ESP to a lower end of a coiled tubing segment containing an electrical power cable. An operator secures a load transfer device with a gripping member to the coiled tubing segment above the ESP. The operator lowers the coiled tubing segment into the well along with the ESP and the load transfer device. The load transfer device contacts an interior side wall of the production conduit with the gripping member and transfers a load on the coiled tubing segment to the production conduit. When powered, the ESP causes well fluid to flow upward from the ESP through the load transfer device up the production conduit.
