Such a portion may acquire heated heavy oil attentive to steam injection. For instance, a REDA™ HOTLINE™ high-temperature ESP motor could also be applied in a thermal recovery heavy oil manufacturing system, equivalent to, for example, SAGD system or different steam-flooding system. As an example, a commercially accessible ESP (similar to one of many REDA™ ESPs marketed by Schlumberger Limited, Houston, Tex.) could also be employed to pump fluid(s). The VSD unit 270 could also be rated with an ESP to supply for about 40,000 hours (5 years) of operation (e.g., relying on environment, load, and so on.). In the example of FIG. 2, the system 200 features a community 201, a properly 203 disposed in a geologic environment, a power provide 205, the ESP 210, a controller 230, a motor controller 250 and a variable pace drive (VSD) unit 270. The facility supply 205 might obtain power from a energy grid, an onsite generator (e.g., natural fuel driven turbine), or different supply.

While the instance of FIG. 2 exhibits an ESP that will embody centrifugal pump levels, another sort of ESP may be controlled. For instance, an ESP motor can embody a three-section squirrel cage with two-pole induction. For FSD controllers, the UNICONN™ motor controller can monitor ESP system three-section currents, three-part floor voltage, supply voltage and frequency, ESP spinning frequency and leg ground, energy issue and motor load. For VSD models, the UNICONN™ motor controller can monitor VSD output present, ESP operating present, VSD output voltage, provide voltage, VSD enter and VSD output power, VSD output frequency, drive loading, motor load, three-section ESP operating current, three-part VSD enter or output voltage, ESP spinning frequency, and leg-floor. In the example of FIG. 2, the motor controller 250 includes various features to handle, for instance, backspin of an ESP, sanding of an ESP, flux of an ESP and fuel lock of an ESP. FIG. 2 shows an instance of a system 200 that includes an ESP 210 for instance of tools that could be positioned in a geologic atmosphere. Well sensors could extend right into a well and beyond a place of an ESP.

For instance, in embodiments that embrace an HNBR insulation shield layer extruded over an EPDM insulation layer, the insulation shield layer might impart enhanced harm resistance along with improved resistance to nicely fluids and gases to the cable. In some embodiments, a jacket could also be constructed from one or more layers of one or more supplies (e.g., consider a number of of EPDM, nitrile rubber, HNBR, fluoropolymers, chloroprene, or another materials providing suitable resistance to downhole circumstances). As an example, a check could also be performed in a stress vessel that includes brine the place at least a portion of a cable and/or a number of cable materials could also be submersed in the brine. As an example, where a period of time could also be of the order of a long time, tools that is meant to last for such a period of time will be constructed with materials that may endure environmental conditions imposed thereon, whether or not imposed by an setting or environments and/or a number of features of the tools itself.

As shown within the plot 1800, the mix of XLPE/PP 75/25 wt % has a plateau storage modulus at a hundred and fifty degrees C. that is comparable in magnitude to that of fully cured XLPE; noting that the plateau storage modulus at a hundred and fifty levels C. of XLPE/PP 50/50 wt % is about one order of magnitude higher than that of fully cured XLPE. FIG. 22 exhibits a plot 2200 of the effect of PP and talc on the plateau modulus of totally cured XLPE. As shown in the plot 2100, the fluid uptake percentage decreased slightly for XLPE/PP/Talc 90/6/4 wt % composite due to the low concentration of PP. FIG. 21 reveals a plot 2100 as to fluid uptake share with respect to PP-talc wt %. In the example of FIG. 2, the VSD unit 270 is proven together with a plot of a sine wave (e.g., achieved through a sine wave filter that includes a capacitor and a reactor), responsiveness to vibration, responsiveness to temperature and as being managed to reduce mean time between failures (MTBFs). In the example of FIG. 2, the motor controller 250 could also be a commercially obtainable motor controller such because the UNICONN™ motor controller.
