For instance, a REDA™ HOTLINE™ excessive-temperature ESP motor may be carried out in a thermal restoration heavy oil manufacturing system, such as, for example, SAGD system or other steam-flooding system. For instance, an ESP may embody a REDA™ HOTLINE™ high-temperature ESP motor. For example, a polymeric insulation layer may embody a single layer or a number of layers of dielectric tape that could be helically wrapped round an electrical conductor and that could be bonded to the electrical conductor (e.g., and to itself) through use of an adhesive. The insulation shield 440 could also be adhered to the insulation 430, but, for instance, removable for splicing (e.g., along with the insulation 430), without leaving a substantial amount of residue. Further, the controller 230 might embody options of a motor controller and optionally supplant the motor controller 250. For instance, the controller 230 may include the UNICONN™ motor controller 282 marketed by Schlumberger Limited (Houston, Tex.). As shown in FIG. 2, the controller 230 can embrace or present entry to a number of frameworks. In the example of FIG. 2, the controller 230 might entry a number of of the PIPESIM™ framework 284, the ECLIPSE™ framework 286 marketed by Schlumberger Limited (Houston, Tex.) and the PETREL™ framework 288 marketed by Schlumberger Limited (Houston, Tex.) (e.g., and optionally the OCEAN™ framework marketed by Schlumberger Limited (Houston, Tex.)).

For instance, the UNICONN™ motor controller can interface with the PHOENIX™ monitoring system, for instance, to access stress, temperature and vibration knowledge and numerous safety parameters in addition to to supply direct current energy to downhole sensors. The SPEEDSTAR™ MVD management circuitry can embrace a plug-and-play sine wave output filter, a multilevel PWM inverter output, a 0.95 power factor, programmable load reduction (e.g., gentle-stall perform), speed management circuitry to maintain fixed load or strain, rocking begin (e.g., for caught pumps resulting from scale, sand, and so on.), a utility energy receptacle, an acquisition system for the PHOENIX™ monitoring system, a site communication field to help surveillance and control service, a speed control potentiometer. HDESPs could handle a large number of fluids and, for instance, as much as about 2% sand, coal, fines and H2S/CO2. For instance, a motor could include windings, and so on., for 3 or more phases. As an example, a flat type factor cable could also be used in low clearance functions within a bore or, for example, in shorter run lengths where a rise in temperature of a center conductor is not an appreciable concern during operation. For example, a method can include extruding polyethylene a few lead (Pb) barrier layer disposed about a conductor to form an meeting; and armoring not less than one of many assemblies with metallic armor to form a cable.

One or more layers may be supplied, for instance, to create an impermeable gasoline barrier. In such an example, the enlargement may trigger the cable 1000 to bulge such that the armor 1080 separates. For example, the properly 203 can embrace a choke valve to regulate various operations resembling to scale back pressure of a fluid from excessive strain in a closed wellbore to atmospheric stress. The VSD unit 270 could embody commercially available management circuitry such because the SPEEDSTAR™ MVD control circuitry marketed by Schlumberger Limited (Houston, Tex.). For instance, the VSD unit 270 might obtain energy with a voltage of about 4.Sixteen kV and control a motor as a load with a voltage from about 0 V to about 4.16 kV. As an example, a curative will be or include a crosslinking agent (CL agent). Such an method can obtain comparatively full crosslinking in a single move.

As an extruded material, the cushion layer 760 differs from braid supplies, which may be formed of nylon or polyethylene terephthalate string, that are mechanically robust during manufacturing but are inclined to hydrolyze rapidly at temperatures above roughly eighty degrees C. in the presence of moisture (H2O). For instance, a multiphase cable can embrace colorants such that a number of of the phases (e.g., phase assemblies) differs in coloration. For example, a pothead unit may be provided as a separate unit configured for connection, instantly or indirectly, to a motor housing. The VSD unit 270 could embody surge and lightening safety (e.g., one safety circuit per section). Well sensors might lengthen right into a well and beyond a place of an ESP. As to the ESP 210, it's shown as including one or more cables 211, a pump 212, gas dealing with features 213, a pump intake 214, a motor 215, a number of sensors 216 (e.g., temperature, stress, present leakage, vibration, and many others.) and optionally a protector 217. The motor 215 is usually a submersible electric motor that's operatively coupled to the pump 212 to drive the pump 212 for movement of fluid (e.g., to pump fluid). In the example of FIG. 2, the VSD unit 270 may be a low voltage drive (LVD) unit, a medium voltage drive (MVD) unit or different kind of unit (e.g., a excessive voltage drive, which may provide a voltage in excess of about 4.16 kV).
