Estimating the term…
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.
An electric cable comprising at least one insulated conductor and one or more armor wire layers surrounding the insulated conductor, wherein the armor wire layer comprises armor wires comprising a high strength core and a corrosion resistant alloy clad, and wherein the corrosion resistant alloy clad is the outer layer of the armor wires.
