Abstract
A hydrocarbon production rotary pump having a stator and a rotor drive to rotate therein by a submersible pump driver is supported so as to be suspended from a wellhead by a support member including production tubing and at least one control line alongside the production tubing. The control line(s) has greater tensile strength in the longitudinal direction of the well casing than the production tubing such that the control line(s) provides greater support to the rotary pump and the submersible pump driver than the production tubing. A unitary casing in the form of a seamless material may fully surround the production tubing and the control line(s) along the full length thereof.
