Electric submersible pump with packer arrangement and method of use

Abstract

An Electric Submersible Pump (ESP)-packer arrangement including a mandrel, an ESP assembly disposed on the mandrel, the ESP assembly including a seal, a motor, and a pump, a packer assembly disposed on the mandrel, the packer assembly including an element, and an electric actuator subassembly configured to set the element, and an electrical cable connected to both the motor and the electric actuator. A borehole system including a borehole in a subsurface formation, and an ESP-packer arrangement disposed in the borehole.

What is claimed is: 
     
         1 . An Electric Submersible Pump (ESP)-packer arrangement comprising:
 a mandrel;   an ESP assembly disposed on the mandrel, the ESP assembly comprising:   a seal;   a motor; and   a pump;   a packer assembly disposed on the mandrel, the packer assembly comprising:   an element; and   an electric actuator subassembly configured to set the element; and   an electrical cable connected to both the motor and the electric actuator.   
     
     
         2 . The ESP-packer arrangement as claimed in  claim 1  wherein the electric actuator is also configured to unset the element. 
     
     
         3 . The ESP-packer arrangement as claimed in  claim 1  wherein the electric actuator is a screw arrangement. 
     
     
         4 . The ESP-packer arrangement as claimed in  claim 3  wherein the screw arrangement includes a lead screw. 
     
     
         5 . The ESP-packer arrangement as claimed in  claim 3  wherein the screw arrangement includes a ball screw. 
     
     
         6 . The ESP-packer arrangement as claimed in  claim 1  wherein the electric actuator is operable in a first direction to set the element and a second direction to unset the element. 
     
     
         7 . The ESP-packer arrangement as claimed in  claim 1  wherein the element is a compression set element. 
     
     
         8 . A method for setting an ESP-packer arrangement comprising:
 running the arrangement as claimed in  claim 1  into a borehole;   sending a signal along the electrical cable to the electric actuator;   operating the electric actuator; and   sending a signal along the same electrical cable to the ESP and pumping fluid with the ESP.   
     
     
         9 . The method as claimed in  claim 8  further comprising operating the ESP. 
     
     
         10 . The method as claimed in  claim 8  wherein the operating is in a direction associated with setting the element. 
     
     
         11 . The method as claimed in  claim 8  wherein the operating is in a direction associated with unsetting the element. 
     
     
         12 . A borehole system comprising:
 a borehole in a subsurface formation; and   an ESP-packer arrangement disposed in the borehole.
