In the resource recovery industry Electric Submersible Pumps (ESPs) are ubiquitously used in boreholes to improve production of hydrocarbon resources. Often ESPs are used in conjunction with a packer that is run to isolate a volume of the borehole from which the ESP draws and a volume of the borehole into which the ESP discharges. Such packers are available from many sources and require differing setup configurations to use with various ESPs from varying manufacturers.
The art would benefit from simplified ESP-Packer arrangements that avoid the need for engineering time to address differing design parameters.
