Where EPDM is included as a predominant polymeric material for insulation (e.g., a base polymer), a compound could also be referred to as an EPDM compound and a ensuing insulation layer could also be known as an EPDM insulation layer. In some embodiments, an insulation shield could also be strippable (e.g., to permit for termination and electrical testing of the cable). For example, in some flat power cable embodiments, two or more particular person coated conductors will be organized in a side-by-side configuration (e.g., consider configurations akin to 2×1, 3×1, 4×1, and so forth.) and, for instance, one or more armor layers could be applied over a jacket. In some embodiments, a jacket could also be constructed from one or more layers of a number of supplies (e.g., consider one or more of EPDM, nitrile rubber, HNBR, fluoropolymers, chloroprene, or one other materials offering suitable resistance to downhole conditions). For example, an insulation compound can include a base polymer, a number of fillers, a number of steel oxides, a number of antioxidants, a number of plasticizers, one or more process aids, one or more curatives and one or more different types of materials. As to a downhole steam generator, for example, it may be fed by three separate streams of pure gas, air and water (e.g., via conduits) where a fuel-air mixture is combined first to create a flame and then the water is injected downstream to create steam.

For instance, a layer 762 could also be a further cushion layer 762 that surrounds the three cushion layers 760 of the grouped assemblies, which may further assist to protect the metallic shields 750 from an armoring process. FIG. 1 shows examples of geologic environments 120 and 140. In FIG. 1, the geologic environment one hundred twenty may be a sedimentary basin that features layers (e.g., stratification) that embrace a reservoir 121 and which may be, for instance, intersected by a fault 123 (e.g., or faults). As to the metallic shield 450 and the barrier layer(s) 460, one or more layers of fabric could also be supplied. For example, an setting may be classified based in one of the aforementioned lessons based on stress or temperature alone. For example, the geologic surroundings 140 may be outfitted with gear 145, which may be, for example, steam assisted gravity drainage (SAGD) tools for injecting steam for enhancing extraction of a useful resource from a reservoir. As to the geologic atmosphere 140, as shown in FIG. 1, it includes two wells 141 and 143 (e.g., bores), which may be, for example, disposed no less than partially in a layer similar to a sand layer disposed between caprock and shale.

In the instance of FIG. 23, the a number of conductors 2310 may be formed from a raw conductor materials (e.g., copper) that has been drawn to a regular wire measurement, annealed, and plated in both a stranded or strong configuration. As such, where well fluid contacts an EPDM insulation layer, damage might occur to the insulation as a consequence of swelling of the EPDM (e.g., which may apply stress that may mechanically damage a number of options of a cable). The one or more processors might execute such instructions to implement (wholly or partially) one or more attributes (e.g., as part of a way). Armor might be supplied as a strip that's wrapped about a number of insulated conductors that can every include an individual lead (Pb) layer. Lead (Pb), at ambient temperature, can have a density that is approximately 11.34 g/cm3. Table 1 exhibits the values of crosslink density for absolutely cured samples calculated from Eqn. FIG. 1 additionally shows the geologic environment one hundred twenty as optionally including equipment 127 and 128 associated with a nicely that features a substantially horizontal portion that may intersect with a number of fractures 129. For instance, consider a nicely in a shale formation that may include pure fractures, artificial fractures (e.g., hydraulic fractures) or a mix of pure and synthetic fractures.

Such tools could embody storage and communication circuitry to store and to speak knowledge, directions, and so forth. As an example, a number of satellites could also be supplied for purposes of communications, information acquisition, and so on. For example, FIG. 1 reveals a satellite in communication with the community 125 which may be configured for communications, noting that the satellite may additionally or alternatively include circuitry for imagery (e.g., spatial, spectral, temporal, radiometric, and many others.). For instance, a motor could embody dielectric oil (e.g., or dielectric oils), for instance, which will help lubricate one or more bearings that assist a shaft rotatable by the motor. For instance, a SAGD operation could lead to condensed steam accompanying a useful resource (e.g., heavy oil) to a well. As proven, the MLEs 500 connect with a motor block 315, which could also be a motor (or motors) of a pump (e.g., an ESP, and many others.) and be controllable through the VSD/step-up transformer block 370. In the example of FIG. 3, the conductors of the MLEs 500 electrically join at a WYE point 325. The circuitry block 350 could derive power through the WYE level 325 and will optionally transmit, receive or transmit and obtain knowledge through the WYE level 325. As proven, the circuitry block 350 could also be grounded.
