Abstract
The present invention provides a electric submersible pump assembly for producing a fluid from a production zone to the surface and operated independently by one or more electric submersible motors using a dual or multiple gearbox, the electric submersible pump assembly including an inlet pump having a section head into which fluid enters from the production zone to the inlet pump, an outlet pump having an intake section communicating with the inlet pump so that fluid received therefrom is discharged through the outlet pump, an electric submersible motor, a first motor interface that connects the electric submersible motor to the inlet pump, and a second motor interface that connects the electric submersible motor to the outlet pump; each motor interface having a gearbox that connects to the electric submersible motor, a pump shaft connector that connects to the pump, and a seal section that joins the pump shaft connector to the gearbox.
