Where EPDM is included as a predominant polymeric material for insulation (e.g., a base polymer), a compound may be referred to as an EPDM compound and a ensuing insulation layer could also be referred to 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 instance, in some flat energy cable embodiments, two or more individual coated conductors can be organized in a facet-by-side configuration (e.g., consider configurations akin to 2×1, 3×1, 4×1, and so on.) and, for example, a number of armor layers might be utilized over a jacket. In some embodiments, a jacket could also be constructed from a number of layers of a number of materials (e.g., consider a number of of EPDM, nitrile rubber, HNBR, fluoropolymers, chloroprene, or another materials offering suitable resistance to downhole situations). As an example, an insulation compound can embrace a base polymer, one or more fillers, a number of metal oxides, a number of antioxidants, a number of plasticizers, one or more course of aids, one or more curatives and one or more other sorts of supplies. As to a downhole steam generator, as an example, it could also be fed by three separate streams of natural fuel, air and water (e.g., by way of conduits) the place a gasoline-air mixture is mixed first to create a flame after which the water is injected downstream to create steam.

As an example, a layer 762 could also be an additional cushion layer 762 that surrounds the three cushion layers 760 of the grouped assemblies, which might additional help to protect the metallic shields 750 from an armoring course of. FIG. 1 exhibits examples of geologic environments one hundred twenty and 140. In FIG. 1, the geologic surroundings 120 could also be a sedimentary basin that includes 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, a number of layers of material may be provided. For instance, an setting could also be categorised primarily based in one of many aforementioned classes based on pressure or temperature alone. For example, the geologic atmosphere 140 could also 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 environment 140, as shown in FIG. 1, it contains two wells 141 and 143 (e.g., bores), which may be, for example, disposed at least partially in a layer comparable to a sand layer disposed between caprock and shale.

In the example of FIG. 23, the one or more conductors 2310 could also be formed from a uncooked conductor materials (e.g., copper) that has been drawn to a normal wire dimension, annealed, and plated in both a stranded or strong configuration. As such, the place properly fluid contacts an EPDM insulation layer, injury may occur to the insulation as a consequence of swelling of the EPDM (e.g., which may apply pressure that can mechanically damage a number of options of a cable). The a number of processors may execute such directions to implement (wholly or partially) a number of attributes (e.g., as part of a way). Armor may be supplied as a strip that's wrapped about one or more insulated conductors that may every embody an individual lead (Pb) layer. Lead (Pb), at ambient temperature, can have a density that is approximately 11.34 g/cm3. Table 1 reveals the values of crosslink density for totally cured samples calculated from Eqn. FIG. 1 additionally shows the geologic setting 120 as optionally together with gear 127 and 128 related to a well that features a substantially horizontal portion which will intersect with a number of fractures 129. For example, consider a properly in a shale formation that may embody natural fractures, synthetic fractures (e.g., hydraulic fractures) or a mix of pure and artificial fractures.

Such equipment may include storage and communication circuitry to retailer and to communicate knowledge, directions, etc. As an example, one or more satellites could also be supplied for functions of communications, information acquisition, and so forth. For example, FIG. 1 exhibits a satellite in communication with the network 125 that could be configured for communications, noting that the satellite tv for pc may moreover or alternatively embody circuitry for imagery (e.g., spatial, spectral, temporal, radiometric, and so on.). For example, a motor may embrace dielectric oil (e.g., or dielectric oils), for instance, which will assist lubricate a number of bearings that help a shaft rotatable by the motor. For instance, a SAGD operation may end in condensed steam accompanying a useful resource (e.g., heavy oil) to a properly. As shown, 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 through the VSD/step-up transformer block 370. In the example of FIG. 3, the conductors of the MLEs 500 electrically connect at a WYE point 325. The circuitry block 350 might derive energy by way of the WYE point 325 and will optionally transmit, obtain or transmit and obtain information through the WYE level 325. As proven, the circuitry block 350 may be grounded.
