ABSTRACT:
Electric cables used with wellbore devices to analyze geologic formations adjacent a wellbore including at least one insulated conductor, and one or more armor wires surrounding the insulated conductor, the armor wires formed of a high strength core surrounded by a corrosion resistant alloy clad. The alloy clad includes such alloys as beryllium-copper based alloys, nickel-chromium based alloys, superaustenitic stainless steel alloys, nickel-cobalt based alloys, nickel-molybdenum-chromium based alloys, and the like. The cables of the invention may be any useful electric cable, including monocables, quadcables, heptacables, quadcables, slickline cables, multiline cables, coaxial cables, or seismic cables.
