It is said that the cable materials for the wellbore application should be selected from the guidelines already provided and by the cable manufacturer, what are the guidelines?

These guidelines include:
•Insulation up to 205°F (96°C) uses polypropylene insulated cables. Over 205°F and up to 450°F (232°C), it utilizes synthetic rubber insulated cables.
•Gassy wellbores use a cable that provides protection from decompression damage. This is a construction that adds hoop strength to the insulation to contain the insulation from expanding and rupturing. Generally, tapes and braids, as well as extruded barriers, provide this protection.
•Hydrogen sulfide (H2S)—generally lead barrier cables are used to protect the copper conductor from damage.
