Where EPDM is included as a predominant polymeric materials for insulation (e.g., a base polymer), a compound may be referred to as an EPDM compound and a ensuing insulation layer may be referred to as an EPDM insulation layer. In some embodiments, an insulation shield may be strippable (e.g., to allow for termination and electrical testing of the cable). For instance, in some flat power cable embodiments, two or more particular person coated conductors may be organized in a aspect-by-side configuration (e.g., consider configurations resembling 2×1, 3×1, 4×1, and many others.) and, for instance, a number of armor layers could be utilized over a jacket. In some embodiments, a jacket could also be constructed from one or more layers of a number of materials (e.g., consider a number of of EPDM, nitrile rubber, HNBR, fluoropolymers, chloroprene, or one other materials providing appropriate resistance to downhole circumstances). For instance, an insulation compound can include a base polymer, one or more fillers, one or more metal oxides, one or more antioxidants, one or more plasticizers, one or more course of aids, one or more curatives and a number of other varieties of materials. As to a downhole steam generator, as an example, it may be fed by three separate streams of natural gas, air and water (e.g., via conduits) the place a fuel-air mixture is mixed first to create a flame and then the water is injected downstream to create steam.

For instance, a layer 762 may be an extra cushion layer 762 that surrounds the three cushion layers 760 of the grouped assemblies, which can further assist to protect the metallic shields 750 from an armoring process. FIG. 1 exhibits examples of geologic environments a hundred and twenty and 140. In FIG. 1, the geologic surroundings one hundred twenty may be a sedimentary basin that includes layers (e.g., stratification) that embrace a reservoir 121 and that may be, for example, intersected by a fault 123 (e.g., or faults). As to the metallic shield 450 and the barrier layer(s) 460, a number of layers of material could also be offered. As an example, an surroundings could also be categorized based in one of many aforementioned lessons primarily based on strain or temperature alone. For instance, the geologic surroundings 140 could also be outfitted with tools 145, which may be, for example, steam assisted gravity drainage (SAGD) equipment for injecting steam for enhancing extraction of a resource from a reservoir. As to the geologic surroundings 140, as shown in FIG. 1, it contains two wells 141 and 143 (e.g., bores), which could also be, for example, disposed at the least partially in a layer such as a sand layer disposed between caprock and shale.

In the example of FIG. 23, the one or more 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 stable configuration. As such, the place well fluid contacts an EPDM insulation layer, damage might happen to the insulation as a consequence of swelling of the EPDM (e.g., which can apply stress that may mechanically injury one or more features of a cable). The one or more processors may execute such directions to implement (wholly or partially) one or more attributes (e.g., as a part of a way). Armor will be provided as a strip that's wrapped about a number of insulated conductors that may every include an individual lead (Pb) layer. Lead (Pb), at ambient temperature, can have a density that's approximately 11.34 g/cm3. Table 1 reveals the values of crosslink density for fully cured samples calculated from Eqn. FIG. 1 additionally shows the geologic atmosphere a hundred and twenty as optionally including equipment 127 and 128 associated with a effectively that includes a considerably horizontal portion that will intersect with one or more fractures 129. For instance, consider a properly in a shale formation which will include natural fractures, synthetic fractures (e.g., hydraulic fractures) or a combination of pure and synthetic fractures.

Such equipment could embody storage and communication circuitry to store and to communicate information, instructions, etc. For instance, one or more satellites could also be supplied for purposes of communications, knowledge acquisition, and many others. For example, FIG. 1 reveals a satellite in communication with the network 125 that could be configured for communications, noting that the satellite may additionally or alternatively embody circuitry for imagery (e.g., spatial, spectral, temporal, radiometric, and many others.). For example, a motor may embrace dielectric oil (e.g., or dielectric oils), for example, that will help lubricate one or more bearings that help a shaft rotatable by the motor. For instance, a SAGD operation might result in condensed steam accompanying a resource (e.g., heavy oil) to a well. As proven, the MLEs 500 hook up 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 by way of the VSD/step-up transformer block 370. In the example of FIG. 3, the conductors of the MLEs 500 electrically join at a WYE level 325. The circuitry block 350 may derive power through the WYE point 325 and will optionally transmit, obtain or transmit and obtain information via the WYE level 325. As shown, the circuitry block 350 may be grounded.
