Prevention of the Factors Affecting Electrical Conductivity of Conducting Material with Use in Chemically Hostile Environment

A steel armored cable connects the downhole electronic equipment present in the well with a surface panel which provides power and different electrical commands during wireline logging operations. This steel armored cable gets corroded by the chemicals and hydrogen sulfide gas present in the well. After corrosion, the chemical reaches the insulation of the cable and starts degrading it. After corrosion and degradation, there is a failure in the conduction electrical signals and electrical power. Failure in the conduction of electrical signals and electrical power supply affects the wireline logging operations. To prevent corrosion and degradation the cable must be washed. Sometimes washing of cable is prohibited at the well site because of water falling into the well and changes the chemical properties of the chemical present in the well. A technique is adopted in which water is used for washing the cable and same water is also prevented from falling into the well
