FIG. Eleven exhibits instance graphics as to some quantity of compression and extension of an assembly 1001 with out a cushion layer in comparison with less compression and extension of an meeting 705 with a cushion layer 760. As indicated in FIG. 11, one or more dimensions and/or shapes may be utilized to characterize an amount of deformation of an meeting, notably an quantity of deformation of a lead (Pb) barrier layer of an assembly. As an extruded material, the cushion layer 760 differs from braid materials, which might be formed of nylon or polyethylene terephthalate string, which are mechanically sturdy throughout manufacturing but are likely to hydrolyze quickly at temperatures above roughly eighty degrees C. within the presence of moisture (H2O). Such a cable can embrace a conductor, an insulation layer over the conductor, a barrier layer atop the insulation layer, and a protective layer including XLPE over the barrier layer. A pump system can include a pump; a submersible electric motor operatively coupled to the pump; and a energy cable for delivery of electrical power to the submersible electric motor, where the power cable includes a conductor, a lead (Pb) barrier layer disposed concerning the conductor, a cushion layer disposed about the lead (Pb) barrier layer the place the cushion layer contains crosslinked polyethylene (XLPE), and metallic armor wrapped in regards to the cushion layer.

As an example, a power cable to be used with an electric submersible pumping system can embrace a conductor, an insulation layer over the conductor, a barrier layer atop the insulation layer, and a protective layer that includes XLPE over the barrier layer. A cable that features an extruded cushion layer may be suitable to be used for a number of installation and retrieval runs. Such one or more cushion layers might help to preserve integrity of a number of metallic shields from a producing course of such as, for example, an armoring process. A way can include controlling a manufacturing process as to one or more of such parameters to achieve a desired amount of crosslinking (e.g., crosslink density of XLPE), for instance, at a sure time during production of a power cable, which can have a optimistic influence on a number of subsequent processes of the manufacturing course of for the ability cable (e.g., consider lessening risk of deformation throughout armoring of the ability cable).

2522-N. For instance, the parts 2522-1 could embody the processor(s) 2502 whereas the part(s) 2522-three might embody reminiscence accessible by the processor(s) 2502. Further, the part(s) 2522-2 may embrace an I/O gadget for show and optionally interaction with a technique. A technique can include extruding polyethylene a couple of lead (Pb) barrier layer disposed a few conductor to kind an assembly; and armoring not less than one of many assemblies with metallic armor to type a cable. To guard a number of electrically insulated copper conductors, metallic lead (Pb) sheaths can be employed as a barrier layer to block permeation of downhole media. Armor may be provided as a strip that's wrapped about a number of insulated conductors that may every embrace an individual lead (Pb) layer. Diameters D1, D2 and d referred in these tables are as per the legend, which shows the standard constructional particulars of a PVC insulated 3-core armored cable. The sorts of cables for which the bodily and electrical properties are shown in these tables as follows. Typical 1 s floor fault rankings for XLPE-insulated 6.35/eleven kV are shown. As to the geologic environment 140, as shown in FIG. 1, it includes two wells 141 and 143 (e.g., bores), which could also be, for instance, disposed at least partially in a layer reminiscent of a sand layer disposed between caprock and shale.

FIG. 1 additionally exhibits the geologic atmosphere a hundred and twenty as optionally including equipment 127 and 128 associated with a properly that includes a considerably horizontal portion that will intersect with a number of fractures 129. For instance, consider a effectively in a shale formation that will include pure fractures, synthetic fractures (e.g., hydraulic fractures) or a mixture of natural and artificial fractures. A thermoplastic extrusion could be carried out at an virtually limitless speed depending on the scale of the gear used and the specifications of the method. Additionally, as mentioned, a metal armoring process may trigger deformation and/or fracturing of a lead (Pb) barrier layer. In such an instance, the metallic shield layer might serve as a ground plane. For example, a cable can include a conductor with a conductor shield that has a radial thickness of roughly 0.010 inch (e.g., roughly 0.254 mm). In such an instance, lateral variations in properties, stresses, and many others. may exist where an evaluation of such variations could assist with planning, operations, and many others. to develop the reservoir (e.g., via fracturing, injecting, extracting, and so forth.). For example, where an environment contains hydrogen sulfide (H2S), carbon dioxide (CO2), and many others., the environment may be corrosive to sure supplies. Various other apparatuses, methods, strategies, etc., are also disclosed.
