Abstract: In a coiled tubing assembly for use in a wellbore, the tubing assembly uses longitudinally spaced apart clamping members to clamp two or more coiled tubing members alongside one another. Each clamping member includes a clamping portion extending circumferentially about each coiled tubing member so as to be rotatable in relation thereto, and a connecting portion joined between the clamping portions. A longitudinal positioning element is fixed relative to one of the tubing members in association with each clamping member such that the clamping member remains pivotal relative to the positioning element and the tubing members upon which it is fixed. The longitudinal positioning element thus only restricts the respective clamping assembly in the longitudinal direction along the tubing members without restricting relative twisting between the tubing members.

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.

Abstract: In a rotary pump having a rotor and a stator in communication with hydrocarbon production tubing, a submersible pump driver assembly includes a drive motor having an output connected by a drive link to the rotor of the pump. A production housing of the drive assembly includes a production passage receiving the drive link in which the output axis of the drive motor is radially offset from the passage. A control line for providing a drive input to the motor is thus suited to extend alongside the production tubing. The driver assembly thus allows for flushing with only a coiled tubing unit as the coiled tubing can be readily inserted past the offset motor and the motor can be optionally run in reverse to improve flushing.
