Abstract: A stress cone for reducing electrical stresses is disclosed for use on terminated ends of tubing encapsulated power cable used in surface applications in a subsurface well power system employing electric submersible pumps (ESPs). The stress cone comprises an annular section about a longitudinal axis for receiving a terminated end of the TEPC in its first end and for abutting the terminated metal TEPC end against a metal shoulder at its second end therein, and an insulation chamber axially aligned with and connected to the annular section. The chamber comprises a metal interior surface symmetrical about the axis. The insulated TEPC core (without outer metal sheath) passes through the insulation chamber along the axis and then exits. The ID of the TEPC metal sheath and the inside metal surface of the chamber form a smooth ground plane transition surface. Insulation material surrounds the TEPC insulation layer within the insulation chamber.

Abstract: A permanent completion system is disclosed comprising: an upper ACP installed in the wellbore powered by a first power cable from the surface; a lower ACP installed in the wellbore below the upper ACP, and being powered by a second power cable from the surface and being connected to the upper APC by a spacer tube; and a heating assembly connected to the lower ACP in the wellbore and receiving power from the second power cable, the heating assembly, such as a mineral insulated heater cable, providing heat to the wellbore. The heating assembly preferably is retrievable and can be conveyed to the lower ACP by coil tubing. The coil tubing can be removed after conveying the heating assembly into place to permit further access to the upper ACP, e.g., to permit mechanical and electrical connection of a retrievable ESP assembly to the upper ACP.

Abstract: A method for implementing asynchronous operation of a permanent magnet motor (PMM) by detecting asynchronous operation of the PMM and creating cyclic variations in the PMM output using the asynchronous operation of the PMM. In another embodiment, an apparatus that comprises a microcontroller that obtains computer executable instructions stored on a non-transitory medium that when executed by the microcontroller causes the apparatus to determine that a rotor shaft within a PMM is rotationally restricted and to vary a plurality of frequencies and a plurality of amplitude currents supplied to the monitor to produce a reverse impact on a downhole tool coupled to the PMM.
