Abstract
An electric submersible pump ESP is run in to a desired subterranean location with a packer attached. Once at the desired location the packer is set either using the ESP or some other source of force or pressure. After the ESP has completed the task and needs to be removed, the packer stays set and the ESP releases from it. Removal of the ESP assembly allows a valve in the packer mandrel to close to isolate the zone from which the ESP had been pumping. The ESP can be run in on coiled tubing or rigid tubing or wireline.
