As an example, a **ercially obtainable ESP (reminis**t of one of the REDA_ ESPs marketed by Schlumberger Limited, Houston, Tex.) may be employed to pump fluid(s). For instance, a high-voltage energy cable could itself pose challenges regardless of the atmosphere into which it is positioned. As an example, a cable could also be utilized as a power cable and deployment cable for a software. As to the insulation shield 440, it might optionally be a semi**ductive material having a resistivity less than about 5000 ohm-m. In some embodiments, an insulation shield layer may be **siderably bonded to an insulation layer (e.g., through cross-linking, and many others.). For example, an surroundings could also be classified primarily based in one of many aforementioned classes primarily based on stress or temperature alone. For instance, a harsh atmosphere may be classified as being a excessive-strain and excessive-temperature atmosphere. For instance, an atmosphere may be categorized based mostly no less than in part on its chemical **position. As an example, a**ra cushion layer could also be utilized that surrounds assemblies where the additional cushion layer is substantially circular in its cross-sectional shape (e.g., an annular wall about a bunch of assemblies).

For instance, a layer 762 may be a further cushion layer 762 that surrounds the three cushion layers 760 of the grouped assemblies, which ** further assist to guard the metallic shields 750 from an armoring process. As illustrated in a cross-sectional view of FIG. 1, steam i**ed by way of the well 141 might rise in a subterranean portion of the geologic setting and transfer heat to a fas**ating resource resembling heavy oil. Such a portion might acquire heated heavy oil responsive to steam i**ion. FIG. 1 also exhibits the geologic enviro** one hundred twenty as optionally including equipment 127 and 128 related to a well that includes a **siderably horizontal portion that will intersect with one or more fractures 129. For instance, **sider a effectively in a shale formation that may embrace pure fractures, artificial fractures (e.g., hydraulic fractures) or a mixture of natural and synthetic fractures. In such an instance, the polymeric layer 634 may encapsulate the three 1 gauge **ductors and their respective layers where, at ends, the polymeric layer 634 could also be about 1 mm thick. For instance, **sider a 3 section cable that includes phase assemblies where each cushion layer of a respective section meeting is colored otherwise to identify the corresponding part (e.g., pink, white, black, green, and so forth.).

As to a downhole steam generator, as an example, it may be fed by three separate streams of pure gas, air and water (e.g., through **duits) the place a fuel-air mixture is mixed first to create a flame and then the water is i**ed downstream to create steam. For example, the geologic enviro** a hundred and twenty may be outfitted with one or more of a variety of sensors, detectors, actuators, and many others. For instance, tools 122 may embrace **unication circuitry to obtain and to transmit **rmation with respect to one or more **works 125. Such data may embrace **rmation associated with downhole gear 124, which could also be equipment to amass data, to assist with useful resource restoration, and many others. Other equipment 126 may be located remote from a effectively site and embody sensing, detecting, emitting or other circuitry. In such an instance, the equipment 145 may be a downhole steam generator and the equipment 147 could also 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 instance of a energy cable 702 where the power cable 700, 701 and/or 702 may be appropriate to be used within the system 300 of FIG. Three or optionally in a number of different te**iques (e.g., SAGD, and many others.).

In the instance of FIG. 2, the system 200 includes a **unity 201, a properly 203 disposed in a geologic surroundings, a energy supply 205, the ESP 210, a **troller 230, a motor **troller 250 and a variable velocity drive (VSD) unit 270. The power provide 205 might obtain power from a energy grid, an onsite generator (e.g., pure fuel pushed turbine), or different source. FIG. 2 shows an example of a system 200 that includes an ESP 210 for instance of tools which may be positioned in a geologic enviro**. For example, the place a time frame could also be of the order of a long time, equipment that is intended to last for such a time frame may be **structed with supplies that may endure enviro**al situations imposed thereon, whether imposed by an surroundings or enviro**s and/or one or more features of the equipment itself. Such a layer will be made with a desired thi**ess to supply for a cable rated to be used specifically circumstances (e.g., per cable specifications). E-beam crosslinking might be carried out without further heat and as such tends to be relatively fast; noting that prices are related to E-beam equipment. While these wraps provide some protection, for max effectiveness, thi**ess tends to matter.
