As an example, a commercially obtainable ESP (reminiscent of one of the REDA™ ESPs marketed by Schlumberger Limited, Houston, Tex.) could also be employed to pump fluid(s). For instance, a high-voltage energy cable might itself pose challenges regardless of the environment into which it is positioned. For instance, a cable could also be utilized as a energy cable and deployment cable for a tool. As to the insulation shield 440, it could optionally be a semiconductive materials having a resistivity less than about 5000 ohm-m. In some embodiments, an insulation shield layer may be considerably bonded to an insulation layer (e.g., by way of cross-linking, and many others.). For instance, an atmosphere could also be categorized based in one of many aforementioned classes primarily based on stress or temperature alone. For example, a harsh atmosphere may be classified as being a excessive-stress and excessive-temperature setting. As an example, an surroundings may be classified based a minimum of partly on its chemical composition. For instance, an additional cushion layer may be applied that surrounds assemblies where the additional cushion layer is considerably circular in its cross-sectional shape (e.g., an annular wall about a group of assemblies).

As an example, a layer 762 may be an extra cushion layer 762 that surrounds the three cushion layers 760 of the grouped assemblies, which may further assist to guard the metallic shields 750 from an armoring course of. As illustrated in a cross-sectional view of FIG. 1, steam injected through the nicely 141 may rise in a subterranean portion of the geologic setting and transfer heat to a fascinating useful resource comparable to heavy oil. Such a portion may acquire heated heavy oil attentive to steam injection. FIG. 1 also reveals the geologic atmosphere one hundred twenty as optionally including gear 127 and 128 related to a well that features a considerably horizontal portion which will intersect with a number of fractures 129. For example, consider a well in a shale formation which will embrace natural fractures, artificial fractures (e.g., hydraulic fractures) or a mixture of pure and artificial fractures. In such an instance, the polymeric layer 634 may encapsulate the three 1 gauge conductors and their respective layers the place, at ends, the polymeric layer 634 could also be about 1 mm thick. For instance, consider a 3 phase cable that includes phase assemblies the place each cushion layer of a respective part meeting is colored in another way to determine the corresponding part (e.g., purple, white, black, green, and so on.).

As to a downhole steam generator, as an example, it may be fed by three separate streams of pure fuel, air and water (e.g., through conduits) the place a gasoline-air mixture is mixed first to create a flame and then the water is injected downstream to create steam. As an example, the geologic environment one hundred twenty could also be outfitted with a number of of a wide range of sensors, detectors, actuators, and many others. For instance, tools 122 might include communication circuitry to obtain and to transmit information with respect to one or more networks 125. Such information might include info associated with downhole gear 124, which could also be equipment to acquire information, to assist with useful resource recovery, and many others. Other equipment 126 could also be positioned remote from a effectively site and embrace sensing, detecting, emitting or different circuitry. In such an example, the gear 145 may be a downhole steam generator and the equipment 147 may be an electric submersible pump (e.g., an ESP). FIG. 7 shows an example of a power cable 700, an example of a energy cable 701, and an example of a power cable 702 where the power cable 700, 701 and/or 702 could also be appropriate to be used within the system 300 of FIG. Three or optionally in one or more other techniques (e.g., SAGD, and so forth.).

In the instance of FIG. 2, the system 200 includes a community 201, a effectively 203 disposed in a geologic environment, a energy provide 205, the ESP 210, a controller 230, a motor controller 250 and a variable velocity drive (VSD) unit 270. The ability provide 205 might receive power from a power grid, an onsite generator (e.g., natural fuel pushed turbine), or different source. FIG. 2 reveals an example of a system 200 that features an ESP 210 as an example of gear which may be placed in a geologic surroundings. As an example, the place a period of time may be of the order of many years, tools that is meant to last for such a period of time might be constructed with supplies that may endure environmental circumstances imposed thereon, whether imposed by an environment or environments and/or one or more capabilities of the tools itself. Such a layer will be made with a desired thickness to supply for a cable rated for use specifically circumstances (e.g., per cable specifications). E-beam crosslinking may be implemented without extra heat and as such tends to be comparatively rapid; noting that prices are related to E-beam tools. While these wraps provide some protection, for maximum effectiveness, thickness tends to matter.
